First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

NTSB narrative

While returning to the airport, the gyroplane started losing altitude and impacted trees approximately 1/2 mile from the airport's only runway. The pilot reported that due to a concussion, he does not recall the events surrounding the accident. The passenger reported that he recalled that they flew over town, were en route back to the airport, and could see the airport when the gyroplane started to lose altitude. As the gyroplane neared the trees, he heard the engine noise increase. Subsequently, the gyroplane impacted trees and came to rest upright. The passenger added that as he exited the gyroplane, fuel was leaking on him. A witness heard the engine at full throttle, heard the rotor blades impact trees, and then the engine noise stopped; however, the witness did not make visual contact with the gyroplane. The pilot held an airline transport certificate, a commercial pilot certificate, and a flight instructor certificate with various airplane ratings; however, he did not hold a rotorcraft-gyroplane category and class rating. The pilot was unaware that he was required to obtain this category and class rating. At the time of the accident, the pilot had accumulated a total of 3.0 hours in gyroplanes.

Probable cause

the pilot's failure to maintain altitude for an undetermined reason, which resulted in an in-flight collision with trees.

  • 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2002-06-14.
  • API snapshot SHA-256: 25f98806af104c9b836fe685898b7835870eab051b776621a2c6d16fdca70a21; retrieved 2026-09-21T09:38:29.691Z.
