Probable cause

The pilot’s failure to maintain airplane control while maneuvering after takeoff.

NTSB narrative

A witness stated that the airplane's takeoff and initial climb appeared normal; however, when the airplane reached midfield, it rolled left. The airplane continued to roll, and it then pitched up. The airplane subsequently returned to a nearly level pitch attitude and then pitched down and collided with terrain. The pilot reported that he did not intentionally roll the airplane after takeoff; however, he was unable to recall specific details regarding the sequence of events and the reason for the abrupt maneuver after takeoff. A postaccident examination of the airframe, including the flight controls and engine, revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
