The NTSB's narrative final · quoted from the NTSB record
The gyroplane pilot reported that, during the landing, the gyroplane began to veer left. He applied right rudder to counteract this, but the gyroplane rolled over to the right and came to rest on the runway, resulting in substantial damage to the rudder, horizontal stabilizer, and vertical stabilizer. The pilot reported that there were no preaccident mechanical malfunctions or failures with the gyroplane that would have precluded normal operation.
