Probable cause
The NTSB’s determination of the probable cause, and any contributing factors.
The pilot's selection of unsuitable terrain for takeoff. Soft, snow covered terrain was a factor in the accident.
Analysis
The pilot, and two passengers, were taxiing for takeoff in a wheel/ski equipped, tailwheel airplane. The flight was a VFR air taxi flight from a remote lake. The landing/departure area was about 3,500 feet long, and covered by soft snow. As the pilot began to taxi, he noticed the snow was softer than anticipated, so he began several taxi runs to pack down the snow for takeoff. During a turn, the right ski encountered soft snow and sank. The right wing struck the snow, and the airplane nosed over. The airplane received damage to the right wing, and propeller.
Factual narrative
On April 3, 1998, about 1900 Alaska standard time, a wheel/ski equipped Cessna 185F airplane, N1205F, sustained substantial damage while taxiing for a takeoff from a remote lake, about 50 miles northeast of Coldfoot, Alaska. The airplane was being operated as a visual flight rules (VFR) on-demand passenger flight under Title 14 CFR Part 135 when the accident occurred. The airplane was registered to the pilot, and operated by North Quest Aviation, North Pole, Alaska. The certificated commercial pilot, and the two passengers were not injured. Visual meteorological conditions prevailed. A VFR flight plan was filed.
During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on April 6, 1998, at 1050, the pilot reported he landed at Squaw Lake about 1830. The landing/departure area was about 3,500 feet long. He loaded his passengers and began to taxi for takeoff from a mining camp. The snow was softer than anticipated, so the pilot began several taxi runs to pack down the snow for takeoff. During a turn, the right ski encountered soft snow and sank. The right wing struck the snow, and the airplane nosed over. The airplane received damage to the right wing, and propeller.
Company personnel reported the flight was overdue, and a search was initiated. Search personnel located the accident site on 4/4/98.
