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 student pilot was on final approach to the destination airport during a solo flight when the engine lost total power. Given the airplane's low altitude, he chose to make an emergency landing in a nearby field, during which the airplane impacted a ditch, nosed over, and came to rest inverted. The airplane erupted into flames and was consumed by fire. The postcrash fire damage precluded examination of the airplane, and the reason for the loss of engine power was not determined based on the available information.
