Accident Summary
While cruising at an altitude of 5,500 feet at night under good weather conditions, the aircraft's number three engine caught fire. The crew responded by feathering the propeller and obtaining permission to divert to Gage Municipal Airport for an emergency landing.
Emergency Landing and Ground Incident
Upon arrival at Gage Municipal Airport, the crew executed a normal landing. However, immediately after touchdown, the right main landing gear collapsed. The aircraft subsequently veered off the runway and came to rest engulfed in flames.
Evacuation
All 82 occupants onboard the aircraft were able to evacuate safely before the fire consumed the entire airframe. The aircraft was totally destroyed by the fire.
Probable Cause
According to the official investigation, the probable cause of this accident was a bearing failure of the No. 3 engine generator. This failure resulted in extreme frictional heat and the release of inflammable fluid, which ignited in flight.
