The NTSB's narrative final · quoted from the NTSB record
The gyrocopter collided with high vegetation and rough terrain during a forced autorotation following the in-flight separation of a propeller blade. The pilot reported that the muffler's mounting strap broke during cruise flight, which caused one composite pusher propeller blade to separate. The pilot autorotated to a forced landing in a ravine. During touchdown the gyrocopter rolled over upon impacting 5-foot-high bushes.
