Aircraft Accident/Incident Report

Wasilla, Alaska 99687
Thursday, October 10, 2002 18:40 AKD

NTSB Narrative Summary Released at Completion of Accident

The flight instructor, seated in the right seat, was providing flight instruction/recurrent training to the private pilot, seated in the left seat, in a wheel-equipped airplane converted to a tailwheel configuration. The private pilot had accomplished two successful stop-and-go landings prior to the accident landing. On the third landing, during landing roll on a dry paved runway, the private pilot allowed the airplane to veer slightly to the left of the runway's centerline. The flight instructor attempted to realign the airplane by applying a slight amount of right rudder, the private pilot simultaneously applied heavy braking, and both wheels locked. The airplane subsequently nosed over, and sustained substantial damage to the wings, fuselage, and empennage. The flight instructor noted that there were no preaccident mechanical anomalies with the airplane.

NTSB Probable Cause Narrative

The instructor's inadequate supervision of the pilot-rated dual student, and the dual student's excessive use of brakes during the landing roll, which resulted in the nose over of the airplane.
