Analysis

The pilot was attempting to land in a hayfield and decided to abort the landing due to rough condition of field. As he pushed the throttle forward, the engine faltered and the plane touched down. The aborted landing was continued due to speed and obstructions. As he cleared power lines, the plane began a steep uncontrolled descending right turn and hit the ground. The engine was running at full power at the time of the stall after the short hesitation in power at the beginning of the abort, according to the pilot.
