Appeal from an order of the Supreme Court at Special Term (Cholakis, J.), entered February 16,1984 in Albany County, which denied a motion by defendant Green Truck Supply, Inc., for summary judgment dismissing the complaint and all cross claims against it.
Plaintiff’s decedent was killed on September 25, 1974 when the tractor trailer he was operating went out of control at a Thruway entrance ramp, crashed through guardrails and rolled down an embankment. This wrongful death action was later commenced against defendant Kenworth Truck Company, the *449manufacturer of the tractor trailer, based, inter alia, on strict products liability and negligence, and against defendant Green Truck Supply, Inc. (hereinafter Green), the alleged repairer of the vehicle, based on negligence. The complaint essentially avers that the cause of the vehicle’s going out of control was a defective “fifth wheel dolly assembly”, a device installed on the tractor for purposes of attaching the trailer to it in the operation of the rig. The device is alleged to have been defective when a trailer is attached by rendering the vehicle difficult to steer and control, causing its cargo to shift and preventing proper weight and traction on the drive wheels of the tractor. During pretrial discovery, plaintiff furnished both defendants with a report of an accident reconstruction expert who concluded that there was no definite manufacturing or maintenance defect which caused or contributed to the accident. Both defendants moved for summary judgment dismissing the complaint and took appeals from the denial thereof, although the matter now before the court only concerns the appeal of Green, the repairer of the vehicle.
In Green’s motion papers, proof in evidentiary form was submitted establishing that (1) it had no contract to provide regular maintenance on the accident vehicle, (2) there was no evidence of its having installed the fifth wheel dolly assembly on the particular vehicle involved in the accident, and (3) its records disclosed that it had not performed any repairs on the fifth wheel dolly assembly for at least three months prior to the accident. Green argues that these facts, coupled with plaintiff’s own expert’s finding of the absence of any mechanical or maintenance defect which could have brought about the accident, negate its liability on the basis of negligence as a matter of law. We disagree.
As asserted in the answering affidavit of plaintiff’s attorney, the gravamen of plaintiff’s claim is that the fifth wheel dolly assembly was defectively designed as to its use to attach a single trailer to a tractor, and the complaint is at least in part subject to that interpretation. Therefore, the fact that the vehicle was found not to contain any significant manufacturing or repair defect does not defeat plaintiff’s action. Regarding Green’s liability, the complaint further alleges in part that Green undertook to repair the subject tractor trailer in response to repeated drivers’ complaints of serious difficulties in steering and controlling the vehicle and nevertheless failed either to properly inspect the device to discover that the steering and control problems related to the foregoing defect in design or, having discerned that the defect existed, failed to warn or give drivers adequate instructions on its proper use. Documentary evidence *450in the record supports the allegations regarding drivers’ complaints on steering and lack of control and their requests for repair some four and five months before the fatal accident.
Even without a general maintenance contract, a repairer may be liable for injuries caused by the unsafe operation of a device if, in response to a complaint concerning the very same operation which later caused the injury, the repairer undertook to make repairs and negligently failed to inspect to find the actual defect (Wroblewski v Otis Elevator Co., 9 AD2d 294, 296-297). There is no good reason why such liability should not apply with respect to a design defect, assuming an expert repairer, such as Green, should have discovered it by reasonable inspection.
It follows from the foregoing that Green’s factual showing on its motion for summary judgment, albeit in proper evidentiary form, was nevertheless insufficient to negate as a matter of law a possible basis of liability in negligence which could be established under plaintiff’s pleadings. Accordingly, the burden did not shift to plaintiff to counter Green’s factual showing by opposing proof in evidentiary form (cf. Zuckerman v City of New York, 49 NY2d 557, 562). Special Term was thus correct in denying Green’s motion for summary judgment.
Order affirmed, with costs to plaintiff. Mikoll, Levine and Harvey, JJ., concur; Kane, J. P., and Casey, J., dissent and vote to reverse in the following memorandum by Casey, J.
