Aircraft Accident/Incident Report
Thompson Falls, Montana 59873
Thursday, June 25, 1998 12:30 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot of the Aeronca 7AC was applying braking during a practice short-field landing. The instructor pilot in the back seat told her to apply more braking, but she did not apply as much as the instructor thought was appropriate. The instructor therefore elected to apply additional braking, whereupon the aircraft started to nose over. As soon as the nose-over started, the instructor pilot released the brake pressure he had applied, but it was too late to keep the aircraft's nose from hitting the runway and the main gear from lifting off the runway surface. After hitting the runway, the aircraft fell back onto its main landing gear with sufficient force to tear one main gear attach fitting from the fuselage.
NTSB Probable Cause Narrative
The instructor's inadequate remedial action with the application of excessive brake pressure.
