Accident

Departure from Miles City was delayed for over an hour due to weather conditions at Billings, but the aircraft eventually departed at 9:14 PM, with only two passengers on board. Shortly after takeoff to the northwest (current runway 31), and at an altitude of

(AGL), the aircraft began a short turn to the left, lost altitude rapidly, and descended almost to the ground. It then pulled up into a sharp climb, reached about 500 feet AGL again, turned left again and descended rapidly into a ravine approximately half-mile southwest of the field.

shortly after the aircraft had departed the airport. Although the state of the wreckage prevented investigators from definitively pinpointing the exact origin of the fire, an area of severe burning was found close to the cross-feed fuel valve located in the cockpit between the pilot and co-pilot. The Super Electra's cross-feed fuel system maintained a constant pressure of approximately , and there had been numerous reports of leakage in the vicinity of the valve. Lockheed designers had not provided any method by which any fuel that did leak from the valve could safely be drained. It was also difficult to maintain or inspect the valve due to its location.

Recommendation

The CAA recommended that the cross-feed fuel system be relocated to allow for easier maintenance and inspection and to reduce the possibility of a cockpit fire caused by fuel leakage. They also recommended that areas of leakage in the fuel line be modified so as to allow for adequate drainage.
