NTSB narrative
Witnesses reported observing the gyroplane take off from the runway, turn left onto the crosswind leg, and climb to about 200 ft. They then saw something fall off the gyroplane before it crashed into an adjacent canal and sank. Postaccident examination revealed that the flight control rod bearing stud exhibited extensive corrosion, consistent with the crack being present before impact. When the rod bearing failed, the main rotor blades went to full pitch, which placed an excessive load on the rotor mast. The rotor mast then folded, which allowed the pusher propeller to strike and sever the tail. The pilot had owned the airplane for 3 years; no records for the gyroplane were located.
Probable cause
The failure of the flight control rod bearing due to an undetected preexisting corrosion-induced crack, which resulted in the main rotor blades going to full pitch and the rotor mast folding; this allowed the pusher propeller to strike and sever the tail.

- 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.
