Probable cause

The pilot's decision to land on a short, icy runway with poor braking action, resulting in a runway overrun/excursion and collision with a snowbank.

NTSB narrative

Prior to touchdown on the snow and ice covered gravel runway with 850 feet of usable length, the pilot reported that the airplane floated a little, but the touchdown point and touchdown were normal. When he applied the brakes, he indicated that there was very little to no braking action. The airplane slid towards the right while in a left yaw, which he was able to correct when the braking action improved. The airplane continued to the end of the runway and impacted a snowbank. The pilot reported there were no preimpact mechanical problems with the airplane. He noted that he walked the runway after the accident, and determined that the braking action would have been slightly better had he landed in the opposite direction. The US Department of Transportation’s Alaska Airport Supplement indicates that the runway should be visually checked for condition before use.
