What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: on Saturday, March 22, 1997, at approximately 0800 PST, N6934Z, an amateur built nieuport 1 gyrocopter began high speed taxi tests on the runway of the "new" Coalinga airport (C80), Coalinga, California. The pilot stated that he was not intentionally attempting to fly the aircraft but to make throttle adjustments during fast speed taxi tests. During his last fast taxi test, the aircraft encountered a brief gust of wind which allowed the main rotor blade to strike the runway and basically disintegrate. The pilot was not injured and there was no fire. Weather was clear. This incident is closed.
