Probable cause & findings

THE CERTIFIED FLIGHT INSTRUCTOR'S FAILURE TO MAINTAIN FLYING SPEED.

Factual narrative

On July 24, 1994, approximately 1000 central daylight time, a Let L-23 glider, N923SB, was substantially damaged during take- off. The instructor pilot and his student were not injured. Visual meteorological conditions prevailed for the 14 CFR 91 flight. During an interview conducted by a Federal Aviation Administration inspector, the instructor pilot reported that the glider was being towed by car for takeoff as part of a student qualification. After separation from the towing vehicle the instructor pilot felt that they were not gaining airspeed and stalled. The glider struck the ground resulting in structural damage. DURING AN INSTRUCTIONAL FLIGHT, A GLIDER WAS BEING TOWED BY A CAR AS PART OF THE STUDENT PILOT'S QUALIFICATION. AFTER SEPARATION FROM THE TOWING VEHICLE, THE INSTRUCTOR PILOT NOTICED THAT THE GLIDER WAS NOT GAINING AIRSPEED. THE AIRCRAFT THEN STALLED AND STRUCK THE GROUND.
