NTSB Narrative Summary Released at Completion of Accident
At an altitude of 1000 feet above ground level (agl) the pilot started the transition between soaring mode and powered flight mode. When completed the pilot observed that throttle movements did not produce power changes. The pilot said he picked a field for an off-airport landing and initiated a normal gliding approach to the field. Between 100 and 150 feet of the off-field landing site the pilot decided to turn into the wind, which was at a 45-degree crosswind, and the left wing tip contacted the ground in a 20-degree bank. The aircraft has a 75.5' wing span. Post accident investigation showed that there was usable fuel in both of the wing tanks. The engine and the drive train were undamaged from the accident. A test run of the engine showed that the engine started, without hesitation, and throttle response was determined to be normal. Engine controls and indications appeared to be in the normal operation limits. No other discrepancies were found.
NTSB Probable Cause Narrative
the improper in-flight decision of the pilot in command to initiate a turn at a close proximity to the ground. Factors to the accident were the starting procedures not being followed and the inadequate altitude to initiate the engine restart.
