Dissenting opinion by Associate Judge TERRY at p. 555.
PER CURIAM:This matter is before the court on appeal from a summary contempt order and a $150.00 fine imposed against appellant, Claude W. Roxborough, an attorney, for being late for two matters in the Landlord and Tenant Branch of the Superior Court on April 5, 1989. Appellant challenges the contempt order on grounds that: (1) the evidence did not establish that his tardiness was deliberate and willful; and (2) the judge abused his discretion in relying on other incidences of tardiness before other judges in justifying the contempt finding. Because Roxborough has not provided us with a record sufficient to show trial court error, we affirm.
On April 6, 1989, Roxborough had a hearing and a trial scheduled before the Landlord and Tenant Branch of the Superior Court. On that same date, however, Roxborough scheduled a matter for 8:15 a.m. in the Prince Georges County Courthouse in Upper Marlboro, Maryland, which is approximately twenty miles from the District of Columbia courthouse. Roxborough later told the court that he completed his business in Upper Marlboro at approximately 9:10 a.m., and was on his way to the District of Columbia when his car broke down. Through the courtesy of another driver, Roxborough was taken to a gas station where he telephoned his office and reported the problem. At about 11:30 a.m., Roxborough’s law partner, George Tillerson, appeared and informed the court that someone from his office had attempted to call the courthouse and report Roxbor-ough’s predicament, but for some unexplained reason, the call could not be put through to the Landlord and Tenant Branch courtroom. The judge directed Tillerson to inform Roxborough to appear in court at 2:00 p.m. and show cause why he should not be held in contempt.
At 2:00 p.m. that afternoon, Roxborough appeared before the Landlord and Tenant Court judge and apologized for his absence that morning. He recounted the reasons for his tardiness, and admitted that he was “cutting it close” by scheduling a matter in Maryland on the same day he was due in court in the District of Columbia. He maintained that, but for the car breakdown, he would have arrived at the Landlord and Tenant Branch courtroom before his cases would have been called. After hearing Roxbor-ough’s explanation, the judge held him in contempt. The record reflects that the trial court issued a formal order of contempt, presumably pursuant to Super.Ct.Crim.R. 42(a), D.C.Code § 11-944 (1989), on April 7, 1989, but that order is not part of the record on this appeal.
I.
An attorney has an obligation to avoid scheduling conflicts. In re Siracusa, 445 A.2d 663, 666 (D.C.1982). When an attorney’s willful failure to appear in court on time for a scheduled proceeding results from a scheduling conflict, this is a breach of professional duty, which often causes disruption of the judicial process. “While breach of this professional duty is punishable by criminal contempt, such an adjudication must be based on a finding, adequately supported by evidence of record, that the failure to appear was the result of willful, deliberate or reck*555less disregard of professional obligations.” Id. (citation omitted).
Roxborough maintains he did not willfully schedule a conflict because: (1) the Maryland matter was set for 8:15 a.m.; (2) based on experience, he estimated the Maryland matter would take about thirty minutes to conclude; (3) also based on his experience, the Landlord and Tenant Court did not begin calling cases before 10:00 a.m., and trials ordinarily did not start until about 11:00 a.m.; (4) but for the unforeseen breakdown of his car, he would have had adequate time to make the approximately twenty-mile ride from Upper Marlboro to the District of Columbia for a timely court appearance. Thus, he argues, his tardiness was not willful. Although the transcript of the April 5, 1989, proceeding is part of the record, the April 7, 1989, contempt order was not designated by Roxborough to be part of the record, and thus it is not before us.
An appellant has the duty to provide this court with a record sufficient to show that error occurred at trial. Cobb v. Standard Drug Co., 453 A.2d 110, 111 (D.C.1982). This rule applies when an attorney appeals an adjudication of contempt against him. In re Gregory, 387 A.2d 720, 723 (D.C.1978); see also Cole v. United States, 478 A.2d 277, 283 (D.C.1984). Without a complete and accurate record, we are unable to determine the basis for the trial court’s ruling or whether any error occurred. For example, we do not know whether the trial court accepted Roxborough’s explanations or whether Roxborough’s estimates of when he could expect his matters to be called in the Landlord and Tenant Branch were accurate. In short, we are unable to determine what the trial court found, because the appellant has not provided us with the contempt order. Accordingly, because appellant failed to provide this court with a record showing trial court error, the judgment of contempt is
Affirmed.
