Probable cause

The pilot's steep right turn shortly after takeoff, which led to the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall.

NTSB narrative

Witnesses observed the airplane lift off and, about midfield, start a right turn. The bank angle continued to steepen until the wings were vertical to the ground. The airplane appeared to be moving very slowly; the nose then lowered directly toward the ground. It is likely that during this steep turn, the airplane exceeded its critical angle-of-attack and stalled. The airplane came to rest about 500 feet abeam the midpoint of the runway, and sustained substantial damage to the wings and fuselage. A caretaker at the pilot's ranch reported that he had observed numerous takeoffs and had never seen the pilot make a midfield turn. The pilot normally turned left or right at the departure end of the runway. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
