Incident
A maintenance test flight experienced a total loss of power in both engines during the approach to the destination airport. The pilot in the right seat took control after the left engine failed and attempted to reach the airport, but the right engine also lost power shortly thereafter. A forced landing was executed on a nearby golf course, during which the airplane struck trees. The right fuel tank separated from the wing, and witnesses reported a fuel odor along the wreckage distribution path.
Pilot Actions
Before departure, the pilot reported that the main fuel tanks were at least half full and the auxiliary tanks were completely full. Another pilot occupied the left seat and was flying the aircraft at the time of the first engine failure. After the left engine lost power, the right-seated pilot assumed control and turned toward the airport.
Post-Accident Examination
Inspection of the intact fuel tanks revealed that the auxiliary tanks contained about one-third fuel, and the left main fuel tank was empty. Both cockpit fuel selectors were found set to the left main tank position. According to the aircraft's emergency procedures, in the event of an engine failure, the fuel selector handles should be turned to their respective tanks for each engine.
