Analysis

The acdnt occurred as the non-certificated plt was operating the non-registered gyroplane in the traffic pattern. Witnesses heard a 'loud crack.' They then observed the gyroplane descending in an apparent unusual attitude. The gyroplane collided with trees, adjacent to the apch end of rwy 24 (aprx 240 ft sse of the threshold). Subsequently, it came to rest, north of the initial impact point, between the trees & the extended rwy centerline. Pieces of the rudder mount were found in the vicinity of where the gyroplane came to rest; the rudder mount's mode of failure was not verified.
