NTSB Factual Report

On May 21, 2001, at 0840 central daylight time, a Beech BE-76 airplane, N6003Y, registered to and operated by Christiansen Aviation, Inc. of Wilmington, Delaware, was substantially damaged when it struck a hangar while taxing at the Richard Lloyd Jones Jr. Airport, Tulsa, Oklahoma. The certified flight instructor (CFI) and his pilot rated student were not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 instructional flight. The local flight was originating at the time of the accident.

The CFI, who was seated in the right seat, reported that the right elevator of the airplane struck a hangar building when the pilot rated student made a left turn while commencing to taxi. The CFI also reported that the flight was intended for his student to practice instrument approaches in a multi-engine airplane. The student held a private pilot certificate with ratings in single engine land and multi-engine land airplanes. The student's total accumulated flight time was 3,000 hours, of which 1,000 hours were in multi-engine airplanes.

Examination of the airplane by an FAA airworthiness inspector revealed that the elevator was buckled. No other mechanical anomalies were noted or reported.

NTSB Probable Cause

the dual student pilot's failure to maintain clearance from the hangar while taxing.
