Accident Summary
Upon touchdown at Chevak, the right main gear of the aircraft failed. The subsequent loss of directional control caused the airplane to veer off the runway surface before coming to a halt. All nine persons on board exited the aircraft without injury. The aircraft, however, was assessed as damaged beyond economical repair due to the impact and structural stress.
Probable Cause and Contributing Factors
The official investigation determined the probable cause of the accident to be a failure of the right main gear during landing. Several factors were identified as contributing to the event: the runway surface was noted to be poorly maintained, the aircraft was operating under an overload condition, wind conditions at the time were unfavorable, and the right main gear became caught in a rut on the runway surface.
