Probable cause

Poor judgement by the student pilot by performing excessive/low altitude maneuvers, which resulted in his failure to maintain sufficient clearance (altitude) above the open field. His lack of familiarity with the aircraft was a contributing factor.

Analysis

The plt of N7037K was in a flt of 2 gyroplanes, flying in-trail of the other acft. When last seen by the lead plt, N7037K was behind, making a diving maneuver toward the ground. The lead plt stated that thru-out their flt, the plt of the adcnt acft had been flying at altitudes ranging fm 1000' AGL to 50' AGL, making steep turns in close proximity to trees & terrain. The lead plt did not see N7037K crash, but found it later, in the vicinity of where he last saw it. N7037K was extensively damage; there was little forward movement of the gyroplane after impact. No preimpact mechanical failure was found. There were no known witnesses to the acdnt. The plt of N7037K held only a student plt certificate.
