Accident Description
A C206 skiplane was attempting takeoff when it decelerated upon encountering deep wet snow prior to lift off. Witnesses on board reported that the pilot elected to abort the takeoff. During the abort, the aircraft veered to the right to avoid trees and subsequently struck a ditch, brush, and irregular terrain, causing the airplane to nose over.
Investigation Findings
On-scene investigation confirmed the runway conditions that supported findings of deep wet snow impeding takeoff. No anomaly was found with the skis themselves, either at the scene or on the accident airplane. Investigators noted that the ski operation may have been the first of the season, and there was no evidence that the pilot had recent experience in snow ski takeoff procedures.
Pilot Report
The pilot reported that he believed the right ski dragged on takeoff due to low tire pressure, which allowed the insert on which the tire rests to drag in the snow. This report was consistent with the observed deceleration and the subsequent loss of directional control.
