Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary

Defining eventThe 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

DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

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.

Probable cause

The pilot’s distraction and failure to maintain adequate airspeed during a low altitude maneuver, which resulted in a loss of aircraft control and collision with terrain.

  • 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, cause areas. 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.
  • API snapshot SHA-256: 3db17a539d70151b5f2c5a96e1cab9b4263ec0972618b8f3963836db8ea49695; retrieved 2026-09-16T12:22:15.212Z.
