Accident Scenario
A flight instructor offered to provide instruction in a tailwheel airplane to a rated commercial pilot who had not previously flown in that make and model. During the flight, the pilot receiving instruction occupied the left seat, while the flight instructor was seated on the right side. The airplane was not equipped with brake controls on the right side, where the instructor was seated.
Sequence of Events
After power was applied, the airplane began to accelerate. The rated commercial pilot, who was controlling the aircraft, did not maintain directional control. The airplane veered to the left. The flight instructor attempted to correct the left veer using rudder input but was unable to do so. The airplane subsequently departed the runway, became caught in a snow bank, and nosed over.
Aircraft and Instructional Context
The accident occurred during an instructional flight intended to familiarize the commercial pilot with the tailwheel airplane. The absence of brakes on the right side may have limited the instructor's ability to intervene. The specific make, model, and registration of the airplane were not reported in the source.
