NTSB narrative

The pilot purchased the used gyroplane about 2 weeks prior to the accident. After assembling it, and 2 days before the accident, he conducted a series of touch and go landings, or "crow hops" along a runway. The day before the accident flight was his first flight. During the accident flight, a main rotor blade "folded," and the gyroplane descended nose first into wooded terrain. Examination of the wreckage revealed airframe and rotor blade marks, consistent with retreating rotor blade stall, which could have resulted from either pilot input or "a sharp downdraft." Winds, about the time of the accident, at an airport 25 nautical miles to the south, were 7 knots, with no wind gusts reported. The make and model of gyroplane was known to be unstable, and the pilot was at least aware of a recommended upgrade kit to enhance stability, but had not installed it. The pilot was not rated in gyroplanes, and had spoken to a flight instructor about training, but then decided to self-train. The pilot also did not possess a repairman's certificate for the gyroplane.

Probable cause

The pilot's improper cyclic input, which resulted in a retreating rotor blade stall, and its subsequent impact with the propeller. Also causal, was the pilot's failure to acquire proper training. A factor was the pilot's decision not to have a stability upgrade kit installed prior to flying the gyroplane.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
