Investigator assessment
Analysis narrative
The pilot intended to complete a 4-hour night flight while following a company multi-engine airplane. Before departure, the airplane was serviced with about 18 gallons of fuel; the main fuel tanks were full (36 gallons usable), and the auxiliary fuel tank was empty. The pilot thought that the airplane contained 53 gallons of usable fuel, even though the auxiliary tank was empty. During final approach to the destination airport the engine lost total power, and the pilot made a forced landing into the airport perimeter fence. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical malfunctions or anomalies with the airplane that would have precluded normal operation. Postaccident examination of the airplane revealed that the fuel tanks remained intact and undamaged. A few ounces of fuel were found in the left main tank, and the right main and auxiliary tanks were empty.
