Aircraft Accident/Incident Report
Anchorage, Alaska 99513
Wednesday, February 1, 2012 16:10 AST
NTSB Narrative Summary Released at Completion of Accident
The pilot was landing the airplane on a runway surrounded by snow berms. He reported that, as the airplane approached the runway threshold, he reduced engine power to flight idle to descend, and the airplane's main landing gear collided with the snow berm at the approach end of the runway. A postflight inspection revealed substantial damage to the left wheel well bulkhead assembly. The pilot said that there were no preaccident mechanical anomalies with the airplane.
NTSB Probable Cause Narrative
The pilot's premature power reduction, which resulted in a runway undershoot.
