OPINION
_________________
AVERN COHN, District Judge. This is a products liability case arising out of a helicopter
accident. Defendant-Appellant B.F. Goodrich Avionics Systems, Inc. (Goodrich) appeals the district
court’s denial of Goodrich’s motion for summary judgment of Plaintiff-Appellee Judy Greene’s
(Greene) manufacturing defect claim and the district court’s subsequent denials of Goodrich’s
motions for judgment as a matter of law and1 motion for judgment notwithstanding the verdict after
a jury returned a verdict in favor of Greene. Greene cross-appeals a pre-trial order granting partial
summary judgment to B.F. Goodrich and an evidentiary ruling by the district court. Because we find
that Greene failed to produce sufficient evidence to create an issue of fact for the jury that there was
a manufacturing defect, we REVERSE the judgment of the district court and REMAND for
proceedings consistent with this opinion.
I. BACKGROUND
A. Factual Background
On the night of June 14, 1999, a Sikorsky 76-A helicopter, aircraft registration number
N2743E, owned by Petroleum Helicopters, Inc. (PHI) and piloted by decedent Donald Greene
(Greene), crashed into a wooded hillside near Jackson, Kentucky. In addition to Greene, pilot-in-
command Ernest Jones (Jones) and two medical technician passengers, Sheila Zellers and Brian
Harden, died in the accident.
The helicopter took off from Julian Carroll Airport just after 8:00 p.m. in heavy fog.
Because visibility was approximately one-quarter to one-eighth of a mile, Greene was forced to rely
almost exclusively on the helicopter’s navigational instruments. Less than two minutes after the
aircraft’s liftoff, an exchange between Greene and Jones recorded on the cockpit voice recorder
(CVR) indicated that Jones told Greene that the helicopter was in a right-hand turn and descending.
The exchange between Greene and Jones continued as follows:

1
The parties refer to the motions made under FED. R. CIV. P. 50 as motions for “judgment as a matter of law”
and “judgment notwithstanding the verdict.” In 1991, however, Rule 50 was amended and the terminology changed to
refer to these motions as a motion for judgment as a matter of law and a renewed motion for judgment as a matter of law.
We hereafter refer to these motions using the current language of Rule 50.
Nos. 03-5017/5018 Greene v. B.F. Goodrich Avionics Systems, et al. Page 3

8:08:05 p.m. Greene: “Okay I think my gyro just quit.”
8:08:10 p.m. Greene: “You have the controls?”
8:08:11 p.m. Jones: “You’re in a left hand turn and descending...turn, turn back
and level, level us off.”
8:08:18 p.m. Jones: “Right hand turn...right hand turn.”
8:08:24 p.m. [Initial sound of impact; CVR ceased operation]
B. Procedural Background
Donald Greene’s wife, Judy Greene, brought this suit, claiming that Goodrich defectively
designed or manufactured the vertical gyroscope portion of the helicopter’s navigation system and
that Goodrich was negligent in failing to warn of its defective product.
Goodrich filed a motion for summary judgment. The district court granted the motion in part
and denied it in part. The district court summarily dismissed Greene’s design defect claim because
she produced no evidence of a flaw in the design. With respect to Greene’s manufacturing defect
claim, the district court held that Greene did not produce evidence of fault under a negligence
theory, but it held that Greene’s manufacturing defect claim sounding in strict liability could go to
a jury because genuine issues of material fact remained with respect to causation. The district court
also held that Greene could not maintain a state-law failure to warn claim because federal law
regarding aviation standards preempted any duty imposed by state law.
At trial on the manufacturing defect claim, the jury found for Greene and awarded her
substantial damages. The jury also awarded damages to Wausau Insurance Co., which had been
paying Greene workers’ compensation on her husband’s death. Goodrich now appeals (1) the
district court’s denial of Goodrich’s summary judgment motion on the manufacturing defect claim;
(2) the district court’s denial of its motion for judgment as a matter of law at the end of Greene’s
case and at the end of the entire case; and (3) the district court’s denial of its renewed motion for
judgment as a matter of law. Greene cross-appeals, challenging the district court’s grant of summary
judgment on her failure to warn claim and the court’s exclusion of evidence of gyroscope failures
that occurred more than six months prior to the helicopter crash.
C. Background on the Product at Issue
Before proceeding to our analysis, it is first prudent to have an overview of the product
Greene claims Goodrich defectively manufactured: the vertical gyroscopes on board the helicopter.
The helicopter was equipped with two Attitude Display Indicators (ADIs), one Standby Attitude
Indicator, and two Horizontal Situation Indicators (HSIs). ADIs indicate an aircraft’s position in
relation to the earth’s horizon and help a pilot control the position of the aircraft relative to the earth.
Each ADI in the helicopter displayed pitch, roll, and turn-rate data. The vertical gyroscopes, model
number VG-204 A/B, manufactured by Goodrich, provided data to the helicopter’s ADIs (which
were not manufactured by Goodrich). The vertical gyroscopes were housed inside the nose of the
helicopter and were not visible to the pilots during flight. Each ADI received pitch and roll data
independently from its own vertical gyroscope. Each ADI also received turn-rate data from two
other gyroscopes not manufactured by Goodrich. The vertical gyroscopes in the helicopter did not
provide data to any other instrument on the helicopter. Pilots use HSIs to determine course
deviation and magnetic heading information. The HSIs in the helicopter received information from
other gyroscopes. The Standby Attitude Indicator is a self-contained unit with its own gyroscope.

II. ANALYSIS
Because this case went to trial and resulted in a jury verdict in favor of Greene, we find it
unnecessary to address whether the district court erred in failing to grant summary judgment in its
entirety to Goodrich. Rather, our analysis will begin by addressing Goodrich’s motion for judgment
as a matter of law at the end of Greene’s case.
A. Whether the District Court Erred in Denying Goodrich’s Motions for Judgment as a
Matter of Law and Renewed Motion forJudgment as a Matter of Law
We review a district court’s denial of judgment as a matter of law de novo. Moore v. KUKA
Welding Sys. & Robot Corp., 171 F.3d 1073, 1078 (6th Cir. 1999). In cases like this one invoking
diversity of citizenship jurisdiction, the Court applies the state law’s substantive standard for
determining when judgment as a matter of law is appropriate. Morales v. Am. Honda Motor Co.,
151 F.3d 500, 506 (6th Cir. 1998); Darwish v. Tempglass Group, Inc., 26 Fed. Appx. 477, 482 (6th
Cir. 2002). Under Kentucky law, judgment as a matter of law should be granted only when “there
is a complete absence of proof on a material issue in the action, or if no disputed issue of fact exists
upon which reasonable minds could differ.” Washington v. Goodman, 830 S.W.2d 398, 400 (Ky.
App. 1992). “[E]very favorable inference which may reasonably be drawn from the evidence should
be accorded the party against whom the motion is made.” Baylis v. Lourdes Hosp., Inc., 805 S.W.2d
122, 125 (Ky. 1991).
1. Judgment as a Matter of Law
Goodrich says that the district court erred by not granting its motion for judgment as a matter
of law against Greene both at the close of Greene’s case and again at the close of trial. As discussed
below, we find that the district court erred by not granting Goodrich’s motion for judgment as a
matter of law at the close of Greene’s case.
a. Manufacturing Defect Legal Standard
Under Kentucky law, a manufacturing defect exists in a product when it leaves the hands of
the manufacturer in a defective condition because it was not manufactured or assembled in
accordance with its specifications. See Ford Motor Co. v. McCamish, 559 S.W.2d 507, 509-11 (Ky.
App. 1977). A manufacturing defect claim requires the jury to determine whether the product failed
because of an error in the process of manufacture or assembly. Id. With respect to Greene’s strict
liability theory, Kentucky has adopted RESTATEMENT (SECOND) OF TORTS § 402A. See Dealers
Transp. Co. v. Battery Distrib. Co., 402 S.W.2d 441, 446-47 (Ky. 1965). Under § 402A, the
defendant is held strictly liable if the plaintiff proves the product was “in a defective condition
unreasonably dangerous to the user or consumer.” Montgomery Elevator Co. v. McCullough by
McCullough, 676 S.W.2d 776, 780 (Ky. 1984). Proceeding under a strict liability theory does not
require the plaintiff to prove fault on the part of defendant. The plaintiff must, however, establish
causation under the “substantial factor” test. King v. Ford Motor Co., 209 F.3d 886, 893 (6th Cir.
2000). “[P]laintiff must prove that the defendant’s conduct was a substantial factor in bringing
about plaintiff’s harm.” Id. Nothing precludes a plaintiff from using circumstantial evidence to
prove a products liability case so long as the evidence is “sufficient to tilt the balance from
possibility to probability.” Id. The Restatement (Second) of Torts provides that “unreasonably
dangerous” means a product that is “dangerous to an extent beyond that which would be
contemplated by the ordinary consumer who purchases it, with the ordinary knowledge common to
the community as to its characteristics.” RESTATEMENT (SECOND) OF TORTS § 402A cmt. i (1965).
“Defective” means “that the product does not meet the reasonable expectations of the ordinary
consumer as to its safety.” Worldwide Equip., Inc. v. Mullins, 11 S.W.3d 50, 55 (Ky. App. 1999).

b. The Evidence at Trial
The vertical gyroscopes were destroyed in the crash; accordingly, there was no direct
evidence of vertical gyroscope failure. Greene instead relied on four major pieces of evidence in
an attempt to circumstantially prove a manufacturing defect in the pilot’s vertical gyroscope:2
First, Greene relied on her husband’s statement seconds before the crash that he thought his
“gyro just quit.”
Second, Greene proffered evidence that in the six-month period preceding the crash, there
had been forty vertical gyroscope replacements on fifteen of the twenty-four Sikorsky 76-A
helicopters owned and operated by PHI. There also had been eleven ADI replacements on seven
PHI helicopters during that same time period. The helicopter that crashed had three vertical
gyroscopes and two ADIs replaced during the six months preceding the crash.
Third, the National Transportation Safety Board (NTSB) retrieved from the crash site a
faceplate of one of the helicopter’s ADIs. The NTSB determined from the faceplate that, at the time
of impact, the ADI indicated that the helicopter was “pointing to a position between level flight and
a 2-degree right roll. . . .”3 The NTSB’s on-site investigation of the ground damage, including the
pattern of treetop leveling and pilot-in-command Jones’s last words, both indicated that, at impact,
the helicopter was actually “in a left hand turn and descending.” As the district court stated, “[t]o
oversimplify, the Cockpit Voice Recorder tape and the crash kinematics did not match the reading
of the recovered ADI.”
Fourth, Greene’s helicopter expert, Douglas Herlihy (Herlihy), testified that it was more
likely that a vertical gyroscope failure, rather than a failure of other instruments, was the cause of
the crash. Herlihy testified that a wiring failure between a vertical gyroscope and its ADI was not
as typical as a gyroscope failure itself.4 He also testified that it was his opinion that “the accident
was a result of instrument confusion in the cockpit created by the loss of vertical gyro input to the
flying pilot’s A.D.I. or gyro horizon.”
c. Goodrich’s Challenge to Greene’s Statement
As an initial matter, Goodrich maintained on brief and during oral argument that Greene’s
statement as recorded on the CVR, “Okay I think my gyro just quit,” was inadmissible hearsay.
Goodrich says that the vertical gyroscopes feeding the helicopter’s ADIs were located in the nose
of the helicopter. Thus, Goodrich argues, it would be impossible for Greene to see a vertical
gyroscope or to know that it quit; rather, he only would be able to see the ADIs inside the cockpit
that reflected data supplied by the gyroscopes. Additionally, Goodrich argues that there were at
least six gyroscopes on the helicopter and that it did not manufacture all of them, so admitting
Greene’s statement requires speculation as to which gyroscope Greene may have been referring.

2
Although there is no distinction in the record between the vertical gyroscopes in the helicopter, it is clear that
Greene’s manufacturing defect claim relates to pilot Greene’s vertical gyroscope.
3
It is unclear from examining the record exactly how the faceplate shows the ADI’s reading on impact.
4
Goodrich says that the district court erred when it admitted Herlihy’s expert testimony because the district
court concluded that Herlihy was not qualified as a gyroscope expert. The record indicates, however, that during a
Daubert hearing, the district court concluded that Herlihy was competent to testify as an accident investigator and to give
his opinion regarding why the vertical gyroscope caused the crash. We find that the district court did not err in admitting
Herlihy’s testimony.
Nos. 03-5017/5018 Greene v. B.F. Goodrich Avionics Systems, et al. Page 6

At the time the district court admitted Greene’s statement, it did not clearly articulate the
hearsay exception on which it was relying. The district court did, however, address this issue with
specificity when it denied Goodrich’s motions for judgment as a matter of law. The district court
at that time found that the statement was admissible under two exceptions to the hearsay rule: (1)
present sense impression and (2) excited utterance.
We review whether the district court’s determination was an abuse of discretion. Mitroff v.
Xomox Corp., 797 F.2d 271, 275 (6th Cir. 1986). Under the Federal Rules of Evidence, hearsay is
defined as a “statement, other than one made by the declarant while testifying at the trial or hearing,
offered in evidence to prove the truth of the matter asserted.” FED. R. EVID. 801(c). Under FED. R.
EVID. 803(1), the hearsay rule does not exclude “[a] statement describing or explaining an event or
condition made while the declarant was perceiving the event or condition, or immediately
thereafter.” The excited utterance exception to the hearsay rule under FED. R. EVID. 803(2) requires
“[f]irst, there must be an event startling enough to cause nervous excitement. Second, the statement
must be made before there is time to contrive or misrepresent. And, third, the statement must be
made while the person is under the stress of the excitement caused by the event.” Haggins v.
Warden, Fort Pillow State Farm, 715 F.2d 1050, 1057 (6th. Cir. 1983).
As an initial note, it is unclear from the record if Greene’s out-of-court statement was even
offered at trial to prove the truth of the matter asserted – the definition of hearsay. Even if it was,
however, the district court did not err in admitting Greene’s statement as either a present sense
impression or as an exited utterance. With respect to a present sense impression, certainly Greene
could not personally observe the vertical gyroscopes in the nose of the helicopter as Goodrich
argues. However, it is undisputed that Greene could see the ADIs in the cockpit that reflected data
supplied by the vertical gyroscopes in the nose of the helicopter. Although Goodrich argues that it
is unclear if Greene was referring to his ADI in his statement or another ADI in the cockpit, the fact
that he said “I think my gyro just quit” (emphasis added) appears to indicate that he was referring
to his ADI. Indeed, Herlihy, Greene’s expert, testified that it would make no difference to an
experienced pilot like Greene that the gyroscope is in the nose of the helicopter. Herlihy testified
that if a pilot like Greene said “my gyro just quit,” he knows that the information displayed on the
ADI is coming from the nose of the helicopter. To suggest that a pilot who is experiencing problems
with an ADI display must physically view the gyroscope to reliably detect a malfunction is
untenable.
The district court also did not err in concluding that Greene’s statement was an excited
utterance. Certainly Greene made the statement while under stress of the event that nineteen
seconds later resulted in his death. To the extent that Goodrich argues again that Greene could not
physically see the gyroscope that allegedly quit, the Advisory Committee Notes to FED. R. EVID. 803
provide that, with respect to a declarant’s perception of an event, “the statement need only ‘relate’
to the startling event or condition, thus affording a broader scope of subject matter coverage.”
Overall, the district court did not abuse its discretion in admitting Greene’s statement.
d. Whether Greene’s Evidence Was Sufficient to Prove a Manufacturing Defect
At the heart of Goodrich’s argument is its position that Greene failed to meet her burden of
proof because she failed to establish an issue of fact for the jury that there was a manufacturing
defect in the pilot’s vertical gyroscope, i.e., Goodrich says that Greene’s evidence failed to “tilt the
balance from possibility to probability” and thus show that there was a manufacturing defect in the
pilot’s vertical gyroscope. See King, 209 F.3d at 893. After a review of the record and an
examination of Greene’s proofs at trial, we agree with Goodrich that the evidence Greene proffered
failed to show that there was a manufacturing defect in a vertical gyroscope.
Nos. 03-5017/5018 Greene v. B.F. Goodrich Avionics Systems, et al. Page 7

Perhaps what is most problematic to us is Greene’s heavy reliance on data indicating the
number of vertical gyroscopes and ADIs that had been removed and/or repaired in PHI-owned
helicopters in the six months preceding the helicopter accident. The parties presented us with
differing interpretations of this data. The NTSB report states that
[a]ccording to company records, in the 6 months that preceded the accident,
fleetwide, there had been a total of 40 vertical gyro replacements on 15 helicopters,
and a total of 11 attitude indicator replacements on 7 helicopters. On N2743E[, the
helicopter piloted by Greene and Jones], in the preceding 6 months, there were two
attitude indicators, and three vertical gyros replaced. According to company records,
fleetwide, in the preceding 6 months, the maximum number of attitude indicators
replaced on a helicopter was three, and maximum number of vertical gyros replaced
was six.
Greene introduced Exhibit No. 21 at trial, titled “S-76 Vertical Gyro Removals” and “S-76 Attitude
Director Indicator Removals,” which purports to summarize the vertical gyroscopes and ADIs from
PHI’s helicopter fleet that were removed, replaced, and/or sent to a repair facility between December
15, 1998 through June 14, 1999. Our review of the data contained in this exhibit does not seem to
correlate with the figures recited above from the NTSB report. Our review of Exhibit No. 21
suggests that PHI removed 32 vertical gyroscopes and 12 ADIs from some of its helicopters in the
relevant six-month period. Regardless of the sum total of vertical gyroscopes and ADIs that were
removed, replaced, or repaired during the six months preceding the accident, however, it troubles
us that Greene argues that the data from this exhibit suggest a “large number” of vertical gyroscope
failures. The vertical gyroscopes and ADIs for which there were repair orders were not sent solely
to Goodrich; rather, PHI sent them to various facilities, including Goodrich; Masco; Helicopter
Support, Inc.; Bell Helicopter Textron; and Honeywell, Inc.5
The evidence in Exhibit No. 21 does not suggest that there was a manufacturing defect in a
vertical gyroscope. Indeed, including ADIs within the list of removals, replacements, and repairs
does nothing to support Greene’s claim that there was a manufacturing defect in a vertical
gyroscope. The evidence in the exhibit could equally suggest that there was a problem with an ADI.
Indeed, counsel for Goodrich at oral argument told us that nothing in Greene’s proofs ruled out the
possibility that an ADI malfunctioned. More significant, however, is the fact that Greene proffered
no evidence that the reason for the removal or repairs of the vertical gyroscopes was unusual.
Likewise, she proffered no evidence that the rate of replacement of vertical gyroscopes in the PHI
fleet differed from the replacement rate of vertical gyroscopes made by other manufacturers.
Because of our uncertainty after studying the record, we expressed concern to counsel at oral
argument about the use of Greene’s data regarding vertical gyroscope and ADI removals,
replacements, and repairs. We directly asked counsel for both Goodrich and Greene to direct us to
the place in the record that would inform us as to the expected useful life of a vertical gyroscope.
Both counsel, however, informed us that the record is devoid of such information.6 This strikes us
as a conspicuous omission, given the fact that without such a benchmark it is impossible to
determine whether the vertical gyroscopes removed, replaced, or repaired in the PHI fleet occurred
at a statistically significant rate compared with the average life expectancy of a vertical gyroscope.
As counsel for Goodrich correctly noted during oral argument, the failure to adduce such evidence
is correctly attributable to Greene – the party with the burden to prove a manufacturing defect.

5
It is unclear if Exhibit No. 21 shows that all vertical gyroscopes that PHI removed were manufactured by
Goodrich because the gyroscopes were sent to various repair facilities.
6
The parties had an opportunity post-argument to respond to our concerns about the lack of this information,
but we received no response.
Nos. 03-5017/5018 Greene v. B.F. Goodrich Avionics Systems, et al. Page 8

Simply put, Greene’s statistics regarding the removal, replacement, and repairs of vertical
gyroscopes and ADIs 7in the PHI fleet are meaningless and are not, without more, probative of a
manufacturing defect.
Greene’s evidence also consisted of Exhibit No. 6, comprising 211 pages of work orders and
inspection reports from Goodrich’s repair station in Austin, Texas. This exhibit documented work
orders Goodrich received from PHI for model VG-204 A/B vertical gyroscopes along with details
of the work Goodrich actually performed on each vertical gyroscope submitted to the repair station
for evaluation. The documents in Exhibit No. 6 detail work orders from PHI to Goodrich for the
period November 1994 through April 1999. Two of the work orders and inspection reports within
six months of the accident show that PHI sent two model VG-204 A/B vertical gyroscopes from the
helicopter Greene was piloting, registration number N2743E, to Goodrich’s Texas facility. The first
work order, number FK956, was received by Goodrich on January 25, 1999. The reason listed on
the work order for the vertical gyroscope being removed was “#2 pitch kicks in flight.” The final
inspection report by Goodrich on January 29, 1999, lists as the reason for failure “carbon build-up
on slip rings and brushes due to electrical contact.” The inspection report states that Goodrich
repaired the vertical gyroscope and that it met manufacturer specifications when it was returned to
PHI on January 29, 1999. The second work order, number FT858, was received by Goodrich on
April 13, 1999. The reason listed on the work order for the vertical gyroscope being removed was,
again, “#2 pitch kicks in flight.” The final inspection report by Goodrich on April 16, 1999, states
“couldn’t verify customer complaint, unit performs normally.” Before the vertical gyroscope was
returned to PHI on April 16, 1999, the work performed on the unit was listed on the final inspection
report as “open checked unit, cleaned all slip ring and brushes as a precaution, calibrated, tested and
inspected to current mfg spec. . . .” This exhibit likewise is not probative of a manufacturing defect
because it does nothing to suggest that any model VG-204 A/B vertical gyroscope listed in the series
of work orders was defective at the time it left Goodrich’s manufacturing plant.
Another piece of evidence further supports our conclusion that Greene failed to prove that
there was a manufacturing defect in a vertical gyroscope. Herlihy testified at trial that it was his
opinion that “the accident was a result of instrument confusion in the cockpit created by the loss of
vertical gyro input to the flying pilot’s A.D.I. or gyro horizon.” PHI lead pilot Thomas Methvin,
however, testified that even if one ADI failed or was receiving incorrect information, Greene and/or
pilot-in-command Jones should have relied upon the other ADIs in the cockpit to safely fly or land
the aircraft. Additional testimony by Herlihy provided that the accident “had a number of factors
that caused it.” Herlihy testified that “the factors include two primary causes,” including the
weather and Herlihy’s opinion that “the helicopter experienced an instrument failure.”
Given the evidence that it would be possible for a pilot to navigate the helicopter if an ADI
failed; that multiple events could have caused the helicopter accident; and that replacements of
vertical gyroscopes on PHI’s helicopters, including the one piloted by Greene and Jones, six months
prior to the crash do not, standing alone, indicate a gyroscope defect, Greene’s proofs were simply
insufficient to show that there was a manufacturing defect in a vertical gyroscope. Indeed, at no
time did any witness identify a defect in manufacture of model VG-204 A/B vertical gyroscopes.

7
This case presents an important example of how the value of oral argument cannot be understated. Oral
argument allowed us to further delve into issues of concern that were not adequately addressed by the parties in their
briefs. “The intangible value of oral argument is, to my mind, considerable. . . . [O]ral argument offers an opportunity
for a direct interchange of ideas between court and counsel. . . . Counsel can play a significant role in responding to the
concerns of the judges, concerns that counsel won’t always be able to anticipate in preparing the briefs.” William H.
Rehnquist, Oral Advocacy: A Disappearing Art, 35 MERCER L. REV. 1015, 1021 (1984).

e. Conclusion
Viewing the totality of the evidence at the conclusion of Greene’s proofs leads us to conclude
that the evidence amounted to “featureless generality.” See OLIVER WENDELL HOLMES, JR., THE
COMMON LAW 89 (Mark DeWolfe Howe ed., Little, Brown 1963) (1881). In the absence of
evidence that one possible explanation was more probable than another, the jury was required to
speculate as to whether there was a defect. It is well established that a jury verdict based on
speculation, supposition, or surmise is impermissible:
Although the jury may draw reasonable inferences from the evidence of a defect in
manufacturing, it is incumbent on the plaintiff to introduce evidence that will support
a reasonable inference that the defect was the “probable” cause of the accident as
distinguished from a “possible” cause among other possibilities; otherwise, the jury
verdict is based upon speculation or surmise.
Midwestern V.W. Corp. v. Ringley, 503 S.W.2d 745, 747 (Ky. 1973). Our view of the evidence
indicates that, at best, Greene only showed at trial that it was possible there was a manufacturing
defect in a vertical gyroscope. She simply failed to satisfy her burden that there was such a defect.
Because we conclude that the district court erred in failing to grant Goodrich’s motion for
judgment as a matter of law at the conclusion of Greene’s case, Goodrich’s challenge to the district
court’s denial of Goodrich’s motion for judgment as a matter of law at the close of trial and the
district court’s denial of Goodrich’s renewed motion for judgment as a matter of law is moot.
B. Whether the District Court Erred in Granting Summary Judgment to Goodrich on
Greene’s Failure to Warn Claim
Greene argues in her cross-appeal that the district court erred when it granted summary
judgment to Goodrich on Greene’s failure to warn claims.
Greene argued that Goodrich breached its duty to warn users of aircraft that contained a
vertical gyroscope about the gyroscope’s manufacturing defects. Greene relied on Herlihy’s opinion
that Goodrich “had no central database structure . . . to track malfunctions, to register employee
concerns of gyro system weaknesses, or to communicate horizontally between Grand Rapids
manufacturing, quality assurance and its field repair facilities.” Greene did not allege any violations
of federal law with respect to the failure to warn claim. She also did not cite any authority regarding
standards that encourage or require a company like Goodrich to maintain such a database.
In granting Goodrich’s motion for summary judgment with respect to the failure to warn
claim, the district court held that federal law preempts any state-law imposed duties in the realm of
aviation. The district court found it significant that Federal Aviation Administration (FAA)
guidelines do not propose or mandate a database like Herlihy suggested Goodrich should maintain.
In reaching its conclusion, the district court relied on Abdullah v. Am. Airlines, Inc., 181 F.3d 363
(3d Cir. 1999). In Abdullah, the Court of Appeals for the Third Circuit joined other circuits in
recognizing that Congress intended aviation safety to be exclusively federal in nature. Id. at 371.
The Supreme Court has stated that preemption may be inferred where “the pervasiveness of the
federal regulation precludes supplementation by the States, where the federal interest in the field is
sufficiently dominant, or where the object sought to be obtained by the federal law and the character
of obligations imposed by it reveal the same purpose.” Schneidewind v. ANR Pipeline Co., 485 U.S.
293, 300 (1988) (internal quotations omitted). The Abdullah court noted that “[t]he federal courts
that adjudicated the first major cases involving the [Federal Aviation Act] interpreted its legislative
history as evincing Congress’s intent to exercise supremacy over the field of aviation safety.”
Abdullah, 181 F.3d at 369. The legislative history of the Federal Aviation Act notes that:
Nos. 03-5017/5018 Greene v. B.F. Goodrich Avionics Systems, et al. Page 10

[The purpose of the Federal Aviation Act was to give] [t]he Administrator of the new
Federal Aviation Agency full responsibility and authority for the advancement and
promulgation of civil aeronautics generally, including promulgation and enforcement
of safety regulations.
H.R. Rep. No. 2360, reprinted in 1958 U.S.C.C.A.N. 3741. The House Report also noted that “[i]t
is essential that one agency of government, and one agency alone, be responsible for issuing safety
regulations if we are to have timely and effective guidelines for safety in aviation.” Id. at 3761.
After analyzing this legislative history, the Abdullah court concluded:
It follows from the evident intent of Congress that there be federal supervision of air
safety and from the decisions in which courts have found federal preemption of
discrete, safety-related matters, that federal law preempts the general field of aviation
safety.
Abdullah, 181 F.3d at 371. We agree with the Third Circuit’s reasoning in Abdullah that federal law
establishes the standards of care in the field of aviation safety and thus preempts the field from state
regulation. The district court did not err in concluding that federal law preempted Greene’s state-
law failure to warn claim.
C. Whether the District Court Erred in Excluding Evidence of Gyroscope Repairs and
Replacements Beyond a Six-Month Timeframe
Greene also argues in her cross-appeal that the district court erred by excluding evidence of
gyroscope repairs and replacements that occurred on PHI’s helicopters more than six months prior
to the crash. When examining a challenge to the exclusion of evidence, we will not reverse the
district court’s decision “unless necessary to do ‘substantial justice.’” Martin v. Heideman, 106 F.3d
1308, 1311 (6th Cir. 1997).
Greene does not adequately explain how evidence of gyroscope repairs and replacements
beyond a six-month time period before the crash would help her case. Indeed, it appears as though
such evidence is cumulative of the evidence she proffered that indicated that there had been several
replacements of vertical gyroscopes on PHI’s helicopters. The district court correctly limited this
type of evidence to a time period of six months prior to the crash so as to prevent the introduction
of unnecessary and cumulative data for the jury’s consideration. Greene has failed to demonstrate
how reversing the district court’s evidentiary decision is necessary to do substantial justice.
III. CONCLUSION
An appellate court does not set aside a jury verdict with ease. Indeed, we previously have
recognized that a reviewing court should not lightly overturn a jury verdict. See, e.g., Pratt v. Nat’l
Distillers & Chem. Corp., 853 F.2d 1329, 1337 (6th Cir. 1988). Not all questions, however, can be
put to a jury, and after a review of the record in this case we conclude that we have an obligation to
REVERSE the decision of the district court and REMAND this case with instructions to enter
judgment in favor of Goodrich and to dismiss this case.

CONCURRING IN PART, DISSENTING IN PART
____________________________________________________
R. GUY COLE, JR., Circuit Judge, concurring in part and dissenting in part. Regarding all
but one of the claims presented in this appeal, I concur in the judgment of the Court. However, I
write separately to clarify my concerns with Greene’s manufacturing defect claim and to respectfully
dissent from the majority’s opinion regarding Greene’s failure to warn claim.
I.
A product failure cannot always be equated to a product defect, and this, as I see it, is the fatal
flaw in Greene’s argument. First, to prevail on a manufacturing defect claim under a strict liability
theory, the plaintiff must show that a manufacturing error, resulting in an unreasonably dangerous
condition, was the substantial cause of the plaintiff’s injury. Worldwide Equip., Inc. v. Mullins, 11
S.W.3d 50, 55-58 (Ky. Ct. App. 1999). As the majority notes, Greene presented four items of
evidence in support of her claim that a vertical gyroscope failure was the probable cause of the crash:
(1) Mr. Greene’s statement immediately prior to the crash that his “gyro just quit”; (2) evidence that
in the six-month period before the crash, several gyroscopes in PHI’s helicopters, including in the
one piloted by Mr. Greene, were replaced; (3) evidence that the crash kinematics did not match what
the helicopter’s instruments were reading at the time of the crash; and (4) Herlihy’s testimony that,
in his opinion, the vertical gyroscope failed on the night of the accident because, based on the remains
of the ADI face plate and light panels from the crash, a vertical gyroscope failure was more likely
than a wiring failure between the gyroscope and its ADI, or a failure of the ADI. With the exception
of the second item of evidence, I find that the sum of Greene’s circumstantial evidence was sufficient
to support the jury’s conclusion that the vertical gyroscope failed.
However, Greene presented no evidence showing that this failure was the result of a
manufacturing defect. Because the gyroscope was destroyed in the crash, Greene could not examine
it for a manufacturing defect. Her argument has essentially been: the gyroscope failed and therefore
there must have been a manufacturing defect. This type of res ipsa loquitur reasoning has been
embraced by Kentucky courts in manufacturing defect cases. See Embs v. Pepsi-Cola Bottling Co.
of Lexington, Kentucky, Inc., 528 S.W.2d 703, 706 (Ky. 1975) (reversing a dismissal where the
plaintiff was injured by an exploding beverage bottle, the debris of which was unrecoverable, because
bottles do not ordinarily explode in the course of normal handling); c.f. Perkins v. Trailco Mfg. and
Sales Co., 613 S.W.2d 855, 858 (Ky. 1981) (reversing a dismissal and noting that circumstantial
evidence was enough to prove a defect where a new tractor trailer collapsed while it was being
properly used). Nevertheless, to be entitled to this res ipsa loquitur-type inference, the plaintiff has
the burden of showing that the product malfunctioned in a way unlikely to occur if the product had
been properly made, and that no outside forces caused the malfunction. See Prosser, Wade &
Schwartz, Torts, 767 (9th ed. 1994); Dan B. Dobbs, The Law of Torts, 1003 (2001). Unfortunately
for Greene, she did not show that it was out of the ordinary for a gyroscope to fail. Goodrich
presented evidence that vertical gyroscopes are not replaced on any set time table. Rather,
gyroscopes are replaced “on condition,” meaning that they are replaced once they show a discrepancy
or failure. These discrepancies or failures occur during flight, and usually, pilots compensate by
relying on the other gyroscopes in the helicopter. The uncontroverted evidence showed that failures
occur and that pilots are trained never to rely solely on one gyroscope for this reason. Greene has
not proven that a gyroscope failure is an unexpected event such that a res ipsa loquitur inference
would be warranted. Accordingly, there was no evidence that the gyroscope failure was a
“manufacturing defect,” and the jury’s outcome to the contrary must be set aside.
Nos. 03-5017/5018 Greene v. B.F. Goodrich Avionics Systems, et al. Page 12

Although the majority goes further to say that the gyroscope failure may not have caused the
crash, I am not convinced that a gyroscope failure, while usually a manageable event, did not prove
fatal in the unique circumstances of this crash. It may be that gyroscopes in certain circumstances
are unavoidably unsafe products, see RESTATEMENT (SECOND) OF TORTS § 402A, Comment K,
however, all the evidence presented indicates that users are aware of their unsafe attributes. Without
showing a probability that Mr. Greene’s gyroscope1 was defective as compared to other gyroscopes
produced by Goodrich, Greene’s claim must fail. Therefore, I respectfully concur in the result
reached by the majority as to Goodrich’s motion for judgment as a matter of law.
II.
I now turn to Greene’s cross-appeal regarding her failure to warn claim. The majority opinion
affirms the district court’s grant of summary judgment to Goodrich, stating that Greene’s state law
failure to warn claim is preempted by federal law. A federal law may preempt a state law either
expressly or implicitly. Garcia v. Wyeth-Ayerst Labs., 385 F.3d 961, 965 (6th Cir. 2004). When
Congress enacted the Federal Aviation Act (“FAA”), it chose several specific areas in which to
explicitly prohibit the States from enacting regulations relating to aviation safety. See 49 U.S.C.
§ 41713(b)(1) (preempting the States from enacting regulations regarding the “price, route, or service
of an air carrier that may provide air transportation”); 49 U.S.C. § 44703(i)(2) (preempting the States
from enacting regulations imposing liability on any person for “furnishing or using records” of
employment); 49 U.S.C. § 44921(f)(2) (preempting the States from regulating when a flight deck
officer may carry a firearm). I can find no congressional language in the FAA which would expressly
preempt Greene’s state law-based failure to warn claim in this case.
When Congress fails to use express preemption language, a federal law may still preempt state
law if the federal law thoroughly occupies the legislative field in question. This Court has previously
held that:
Implied preemption occurs if a scheme of federal regulation is so pervasive as to
make reasonable the inference that Congress left no room for the States to supplement
it, if the Act of Congress touches a field in which the federal interest is so dominant
that the federal system will be assumed to preclude enforcement of state laws on the
same subject, or if the goals sought to be obtained and the obligation imposed reveal
a purpose to preclude state authority . . . a court must begin with the assumption that
a state law is valid and should be reluctant to resort to the Supremacy Clause.
Garcia, 385 F.3d at 965.
Under this implied preemption reasoning, the district court determined that federal law
preempted state law on the issue of aviation safety duties. The district court cited Abdullah v.
American Airlines, Inc., 181 F.3d 363 (3d Cir. 1999) in support of this proposition. As the majority
notes, the Third Circuit in Abdullah did a close study of the legislative history of the FAA. In
Abdullah, passengers who were injured during a flight sued the airline for operating the aircraft in
a manner that resulted in severe turbulence. 181 F.3d at 365. The court stated that:

1
I recognize the difficulty of proving a manufacturing defect in a situation where the product is destroyed. This
is why the res ipsa loquitur inference could prove important in many cases. Here, however, there is an additional
complication, because the product, by all accounts, is sometimes expected to fail. If Greene had presented evidence on
the expected rate of failure in gyroscopes, she perhaps might have been able to show that a user would not have had any
expectation that a relatively new gyroscope would fail, and therefore that a manufacturing defect was the likeliest
possibility. Greene may have an argument that Goodrich has the burden to collect and provide consumers with
information regarding the gyroscope’s failure rate. See infra.
Nos. 03-5017/5018 Greene v. B.F. Goodrich Avionics Systems, et al. Page 13

To effectuate this broad authority to regulate air safety, the Administrator of the FAA
has implemented a comprehensive system of rules and regulations, which promotes
flight safety by regulating pilot certification, pilot pre-flight duties, pilot flight
responsibilities, and flight rules.
Id. at 369. The court, noting that federal regulations lay out the appropriate standard of care that is
owed to passengers by pilots and flight crews, concluded that the FAA preempted any standards of
care that the State may impose on flight operators. Id. at 371. To the extent that we choose to rely
on Abdullah as persuasive authority, I believe that the facts of the instant case are readily
distinguishable. Abdullah can truly only be relied on for the limited proposition that a State’s
standard of care for aviation personnel is preempted by the FAA. The situation before us is not like
that in Abdullah, because in this case, there are no federal regulations which lay out the exact
standard of care. Therefore, I would not expand the proposition in Abdullah to apply to commercial
enterprises that manufacture aviation equipment.
Furthermore, this Court has previously chosen to apply preemption narrowly with regards to
the FAA. In Gustafson v. City of Lake Angelus, 76 F.3d 778, 786 (6th Cir. 1996), we stated that
Congress had preempted local law regarding navigable airspace, noise control, and aircraft safety,
but went on to hold that the FAA did not preempt local regulations/ordinances regarding ground
space to be used for aircraft landing sites. Id. at 789. Thus, our circuit has traditionally shown a
proper amount of restraint and caution before finding State and local laws preempted by federal law.
Under this regime, I cannot assume that the FAA implicitly preempts any State or common law-
imposed duties here. Admittedly, the FAA is involved in overseeing the quality control of certain
aviation equipment; however, neither the appellant nor the majority have proffered any reason why
a State’s more stringent duty of care in the failure to warn context could not supplement rather than
frustrate the FAA. Consequently, I respectfully dissent from the majority’s conclusion that Greene’s
failure to warn claim was properly dismissed.
