Aircraft Accident/Incident Report

Wauchula, Florida 33873
Sunday, March 2, 1997 16:46 EST

NTSB Narrative Summary Released at Completion of Accident

The home built, powered glider was being flown on a flight to conduct a stall test at 3,000 feet. A witness observed the powered sailplane flying westbound at low altitude. According to the witness, the powered sailplane entered an abrupt turn to the east, then it started rotating to the left in a descent until it disappeared from view below a tree line. Examination of the crash site revealed evidence that the powered sailplane collided with the ground in a near vertical descent, 10-degree nose-up attitude, with no evidence of forward motion, rotating around its vertical axis to the left. Examination of the airframe, flight control assembly, engine assembly, and accessories revealed no evidence of a precrash mechanical failure or malfunction. The powered sailplane had accumulated about 4 hours of flight time, since it was built.

NTSB Probable Cause Narrative

failure of the pilot to maintain adequate airspeed, while maneuvering, which resulted in an inadvertent stall/spin and subsequent collision with terrain.
