HALLEY KFT APOLLO
According to the pilot of the experimental amateur-built gyroplane, he landed on a taxiway and taxied to the runway intersection. The intersection was on the right side of runway 30R. The ramp where the pilot wanted to park, was across both runways, on the left side of runway 30L. Unfamiliar with the capabilities of the gyroplane, the tower controller asked the pilot to air taxi to the ramp. The pilot informed the tower controller that he could either ground taxi or takeoff and land on runway 30L then taxi to the ramp. The controller and the pilot agreed to the latter. The pilot further reported that, in anticipation of taxiing to parking, he had allowed the gyroplane's rotor speed to decrease; when he turned the gyroplane back onto the taxiway in the gusting wind, the main rotor struck the empennage and the pusher-propeller. The gyroplane sustained substantial damage to the empennage and rotor system. The METAR at the accident airport reported that about the time of the accident, the wind was from 330° at 14 kts and gusting to 19 kts. The pilot reported that this accident could have been prevented if he had waited for the rotor blades to stop completely before repositioning the gyroplane for taxi. The pilot reported that there were no preaccident mechanical malfunctions or failures with the gyroplane that would have precluded normal operation.

The METAR at the accident airport reported that about the time of the accident, the wind was from 330° at 14kts and gusting to 19kts. Per the National Transportation Safety Board's Pilot Aircraft Accident Report, the pilot identified in the Owner Safety Recommendation section, that this accident could have been prevented if he had waited for the rotor blades to stop completely before repositioning the gyroplane for taxi. The pilot reported that there were no preaccident mechanical malfunctions or failures with the gyroplane that would have precluded normal operation.
The pilot’s failure to stop the main rotor rotation before taxiing the gyroplane in gusting wind conditions, resulting in the main rotor striking the empennage.
