Probable cause

The flight instructor’s delayed remedial action to prevent the airplane from hitting the hangar door. Contributing to the accident was the student pilot's misuse of the airplane's throttle, and his incorrect use of the wheel brakes.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The student pilot reported that, while taxiing to the runway and adjusting the throttle, the engine spooled up and the taxi speed increased. He retarded the throttle and attempted to apply toe brakes, but the airplane was equipped with a hand brake instead of toe brakes. The flight instructor reported that the airplane moved toward a hangar at a "rapid speed" as he tried to slow the airplane. The airplane collided with a hangar door, resulting in substantial damage to the airframe. The instructor stated that the time from loss of control to the collision with the hangar was about 2 to 3 seconds. The instructor had 1.9 hours of experience in the accident airplane. The pilots reported that there were no anomalies or malfunctions with the airplane during the accident sequence.
