Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that about 4 hours and 15 minutes after departure, the engine lost all power. The pilot was successful in restoring engine power by switching fuel tanks and turning on the auxiliary fuel pump. However, the engine lost all power again about 5 miles from the destination runway. The pilot conducted a forced landing to a field, during which the airplane struck a fence resulting in substantial damage to both wings. Postaccident examination of the airplane revealed that the fuel tanks contained no usable fuel. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
