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 departed with an estimated 5 gallons of fuel, and had begun his descent to his destination airport when the engine lost all power. He established best glide speed and made a forced landing to an open stretch of road. The airplane touched down hard, spun 180 degrees, and came to rest in a ditch. The airplane sustained substantial damage to the fuselage. The pilot stated that there was very little fuel found in the fuel tanks during recovery of the wreckage and that he believes he may have run out of fuel.
