Cessna 208 N454SF accident near Hooper Bay, Alaska

Probable cause

The pilot’s decision to depart from a contaminated runway, and his failure to make a timely decision to abort the takeoff when the airplane was not accelerating as expected. Contributing to the accident was the pilot’s decision to depart in limited visibility conditions, which likely affected his ability to determine the available runway distance remaining during the takeoff.

NTSB analysis

While taking off from a snow-covered runway in instrument meteorological conditions, the pilot stated that the airplane was not gaining speed as expected, but that there was inadequate runway remaining on which to abort the takeoff. The airplane became airborne, and the stall warning horn activated; the airplane subsequently settled back onto the ground, the nose landing gear impacted terrain, and the airplane came to rest upright off the departure end of the runway, resulting in substantial damage.
