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 of the gyroplane reported that, while maneuvering at low altitude over a friend’s property, he looked down and backwards to the ground and inadvertently pulled back on the control stick, slowing the gyroplane to about 20 mph. He attempted to correct by applying full engine power and descending to reestablish airspeed. Concerned the gyroplane would impact trees, he flared just above a wooded area. The gyroplane fell through the trees to the ground substantially damaging the tail section. The pilot reported that there were no preaccident mechanical failures or malfunctions with the gyroplane that would have precluded normal operation.
