Probable cause

The student pilot’s failure to maintain sufficient airspeed, which resulted in a loss of altitude and necessitated a sudden descent to unsuitable terrain.

Findings · 5

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

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 solo student gyroplane pilot reported that he "was flying behind the power curve," and the gyroplane lost altitude. He added that he couldn't tell if there were power lines ahead and decided to conduct a "hard vertical de[s]cent landing." The terrain was uneven, and the gyroplane rolled onto its side during landing. The student added that, before he decided to land, he got distracted for a few seconds and descended below a safe altitude. The gyroplane sustained substantial damage to the rotor, fuselage, and empennage. The student reported that there were no preaccident mechanical failures or malfunctions with the gyroplane that would have precluded normal operation.
