Aircraft Accident/Incident Report
King Salmon, Alaska 99613
Saturday, April 21, 2001 14:00 AKD
NTSB Narrative Summary Released at Completion of Accident
The commercial certificated pilot was landing on runway 29 at an airport which was an intermediate stop on a cross-country government flight. The wind conditions were reported to the pilot as 070 degrees at 6 knots. After touchdown, the airplane veered to the left. The pilot applied right rudder and right brake pressure, but the airplane continued to the left. The right wingtip and the right aileron struck the gravel-covered ground along the left side of the runway. The wingtip was bent upward slightly, and the trailing edge of the right aileron was buckled upward. The pilot decided the airplane was airworthy, and continued the flight to his final destination.
NTSB Probable Cause Narrative
The pilot's inadequate compensation for wind conditions, and inadequate weather evaluation resulting in a loss of directional control during the landing roll. Factors in the accident were the presence of a quartering tailwind, and an inadvertent ground loop.
