Probable cause

The non-certificated pilot's exceedance of the airplane's critical angle of attack during a low-level turn, which resulted in an aerodynamic stall.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The non-certificated pilot reported that shortly after departing from the airstrip, he decided to maneuver the airplane back toward the airstrip. The airplane was 200 ft agl and the airspeed was about 50 mph when the pilot initiated a left turn and applied “hard right rudder.” The pilot reported that the airplane’s left wing suddenly dropped straight down and the airplane “apparently stalled.” The airplane impacted the ground and came to rest in a ditch. The airplane sustained substantial damage to the fuselage and both wings. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe and engine that would have precluded normal operation.
