Probable cause
The pilot's failure to maintain adequate airspeed to avoid an aerodynamic stall during takeoff/initial climb.
Findings · 2
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot reported that the takeoff roll was normal and that he used the standard Short Takeoff and Landing (STOL) takeoff procedure. After climbing to about 50 to 75 feet, the right wing suddenly lifted and the wing slats lost their STOL lift. The pilot stated that the airplane then slipped to the left, and being unable to recover, the left wing impacted the ground, which resulted in the airplane cartwheeling and coming to rest inverted. The airplane sustained substantial damage to both wings and the empennage. The pilot reported no mechanical anomalies with the airplane that would have precluded normal operation.
