Accident Details
The accident occurred during a Title 14, CFR Part 135 cargo flight. The pilot, who held an airline transport pilot certificate, was landing a wheel-equipped airplane on runway 23. The pilot reported that the wind at the airport was from 180 degrees, with a strength of 10 knots or greater, as indicated by streaks of white foam on many nearby lakes that appeared perpendicular to the runway.
Sequence of Events
During the landing roll, the airplane suddenly veered to the left. The pilot applied right brake and right rudder in an attempt to correct the deviation. Despite these inputs, the airplane departed off the left side of the runway, rolled down an embankment, and collided with a ditch.
Damage
The airplane sustained structural damage to the left main landing gear assembly, the left aileron, and the fuselage.
Pilot Comments
In the recommendation section of the NTSB accident report, the pilot indicated that he should not have landed with the existing crosswind. No other causal factors were identified in the source material.
