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. ## Factual narrative The pilot reported that the takeoff roll was normal and that he used the standard Short Takeoff and Landing (STOL) takeoff procedure.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
