Factual narrative

WHILE ON A LOCAL PERSONAL FLIGHT THE AIRPLANE SUSTAINED A TOTAL LOSS POWER. THE PILOT NEGOTIATED SEVERAL TURNS IN SEARCH OF A SUITABLE LANDING AREA. THE PILOT THEN EXECUTED A SHARP 90 DEGREE TURN AND STALLED THE AIRPLANE. EXAMINATION OF THE WRECKAGE DISCLOSED THAT THE PILOT IMPROPERLY SELECTED THE FUEL SELECTOR VALVE TO THE LEFT TANK WHICH DID NOT CONTAIN ANY FUEL. THE RIGHT TANK WAS FOUND NEARLY FULL OF FUEL.
