Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot's inadvertent activation of the right brake pedal during the landing roll.

Analysis

The pilot, flying from the right seat, was landing on a remote airstrip with two passengers on a personal cross-country flight. After touchdown in calm wind conditions, the pilot reported that she inadvertently depressed the right brake pedal as a result of wearing large boots. The airplane veered to the right and struck a snow berm along the right side of the airstrip. The airplane received damage to the left gear, left wing, and left stabilizer.

Factual narrative

On March 4, 1995, about 1300 Alaska standard time, a wheel equipped Cessna 185F, N6166N, sustained substantial damage when it crashed during landing at a private airstrip at Port Alsworth, Alaska. The airplane was being operated as a visual flight rules (VFR) cross- country personal flight when the accident occurred. The certificated private pilot (the first pilot), seated in the right front seat, the owner (the second pilot), seated in the left front seat, and one additional passenger were not injured. Visual meteorological conditions prevailed and a VFR flight plan was filed. The flight originated from a frozen lake about 20 miles west of Iliamna, Alaska, at 1230 as a continuing portion of the flight.

The owner reported that after touchdown, the first pilot who was performing the landing, inadvertently depressed the right brake pedal as the result of wearing large boots. The airplane swerved to the right and struck a berm on the right edge of the runway. The airplane received damage to the left landing gear, left wing, left horizontal stabilizer and elevator. The owner indicated that the wind conditions were calm.
