Location:Big Lake, AK -   United States of America
Phase: Take off
Nature:Training
Departure airport:Big Lake, AK (BGQ)
Destination airport:Anchorage, AK (MRI)
Investigating agency: NTSB
Narrative:
The pilot reported that he was attempting to take off from a snow-covered runway and that, during the first attempt, the airplane failed to generate enough airspeed, so he aborted the takeoff and exited the runway. On his second attempt, he chose to begin the takeoff roll with a high-speed taxi on a taxiway before turning 90 to enter the runway. Just before entering the runway, the airplane hit a dip in the taxiway, and the airplane veered left and impacted a snow berm, which resulted in substantial damage to the right wing. The pilot reported several ways that the accident could have been prevented, including parking the airplane and waiting for a snowplow to clear the runway. In addition, he indicated that he was fatigued and that his judgment and decision-making abilities were compromised.



Probable Cause: The pilot's improper decision to initiate the takeoff roll from a snow-covered taxiway, which resulted in a loss of directional control, runway excursion, and impact with a snow berm.
