Probable cause

The loss of gyrocopter control for reasons that could not be determined because postaccident examination of the gyrocopter revealed no mechanical malfunctions or failures that would have precluded normal operation.

NTSB narrative

The sport pilot reported that, while performing maneuvers in the gyrocopter south of the private airstrip, he felt no response when he applied left cyclic, and the gyrocopter "was stuck in a moderate right turn." The pilot initiated an emergency descent back to the private airstrip. During the approach, the pilot was unable to regain control of the gyrocopter, and it impacted terrain while sliding to the right. The gyrocopter rolled over and came to rest on its right side. Postaccident examination of the gyrocopter revealed no evidence of preimpact mechanical malfunctions or failures that would have precluded normal operation.
