The private pilot/owner of the experimental amateur-built airplane was attempting to land on the 431-ft-long grass airstrip for the first time. According to a witness, before the accident, the pilot had flown three practice approaches without landing. The witness reported that, during the fourth approach, the airplane entered a steep-bank-angle turn onto final approach and then "went straight down" to ground impact. The airplane came to rest on its nose, and a fire erupted. The witness' description of the event and the impact geometry are consistent with the pilot conducting a steep turn that resulted in the wing exceeding its critical angle-of-attack and a subsequent aerodynamic stall. Examination of the wreckage did not reveal evidence of any preimpact mechanical malfunctions or anomalies that would have precluded normal operation of the airframe or engine.
Probable Cause: The pilot's failure to maintain control of the airplane during final approach, which resulted in the airplane's wing exceeding its critical angle-of-attack and a subsequent aerodynamic stall.
