Analysis

Pilot entered right downwind from a mid field crossing. Half way through the right turn to downwind, the airplane experienced an inflight loss of control. Witnesses stated the engine appeared to lose power, then the airplane pitched over about 45 degrees, and remained in that attitude until collision with the terrain. The investigation disclosed no pre-impact malfunctions of the airplane or engine.
