Private Grass Airstrip Airport
Aircraft Accident/Incident Report

Jackson, Wyoming 83001
Friday, June 28, 2013 15:00 MDT

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate airspeed to avoid an aerodynamic stall during takeoff/initial climb.
