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 was flying with a pilot rated passenger who was becoming familiar with the flight characteristics of the airplane. As they turned final for the runway, the airplane began a rapid descent. The. pilot took control of the airplane and added full power for a go-around; however, he was unable to recover. The airplane subsequently struck an airport light pole, lost directional control, and came to rest inverted in a gravel parking lot, resulting in substantial damage to the wings and fuselage. The pilot stated he did not monitor the developing situation fast enough to recover. He reported that the airplane had no preimpact mechanical malfunctions or failures that would have precluded normal operation.
