2017-11-18 Casa Grande, Arizona, United States Airport · CGZ Minor 1 aircraft Status: Completed

Aircraft involved

Probable cause & findings

The pilot’s improper landing flare, which resulted in loss of directional control and a subsequent runway excursion.

Factual narrative

The pilot reported that, during landing, the right wheel touched down first on the runway and the gyroplane veered to the right. He added that, the "aircraft bounced from one wheel to the other" multiple times until the main rotor blade struck the runway. The gyroplane then rolled to the right, slid off the runway and came to rest on its left side. A post-crash fire ignited in the engine compartment and consumed the gyroplane. The gyroplane was destroyed. The pilot reported that there were no preaccident mechanical failures or malfunctions with the gyroplane that would have precluded normal operation.
