Probable cause

The pilot's improper compensation for the wind conditions and the resultant inadvertent stall. Factors related to the accident were: the gusty crosswind condition and the pilot's extension of full flaperons before descending to the proper altitude.

Analysis

At about 100 feet AGL on final approach, the pilot had the flaperons fully extended and encountered a gust. Control was lost and the pilot attempted to land in an adjacent field. The airplane stalled and impacted right landing gear first and nosed over. The pilot/builder reported that the airplane flight manual recommended full flaperons be used at 20 feet AGL or less. He further related that he was not accustomed to the slower roll rate with full flaperons extended.
