Aircraft Accident/Incident Report

Gakona, Alaska 99586
Wednesday, May 9, 2012 18:15 AKD

NTSB Narrative Summary Released at Completion of Accident

The pilot departed from a remote, 800-foot-long, gravel-covered airstrip in variable wind conditions. He said that during the takeoff roll, just before liftoff, a gust of wind pushed the airplane to the right. As the airplane became airborne, the pilot felt a "bump," but he noted no control or vibration problems. After an uneventful landing at his destination airport, an examination revealed substantial damage to the lower portion of the airplane's rudder. Further examination revealed that the tailwheel likely hit something during takeoff. The pilot reported that there were no preaccident mechanical anomalies with the airplane.

NTSB Probable Cause Narrative

The pilot’s decision to take off in variable wind conditions, which resulted in a loss of control and the airplane striking an object after takeoff.
