WHILE MANEUVERING OVER MOUNTAINOUS TERRAIN AT 500 FEET ABOVE GROUND LEVEL, THE AIRPLANE PASSED OVER A RIDGE LINE THEN DROPPED INTO A CANYON. THE PILOT STATED THAT A 'SEVERE DOWNDRAFT JOLTED THE AIRPLANE...,' AND THE ENGINE LOST POWER. THE PILOT WAS UNABLE TO RESTART THE ENGINE AND THE LANDING GEAR WOULD NOT LOCK DOWN. A FORCED LANDING WAS MADE TO AN OPEN ROUGH FIELD. DURING THE LANDING ROLL, THE AIRPLANE COLLIDED WITH THE TERRAIN. AN EXAMINATION OF THE WRECKAGE REVEALED A TRACE OF WATER CONTAMINATION IN THE FUEL SYSTEM. NO EVIDENCE WAS FOUND TO INDICATE A MECHANICAL FAILURE OR MALFUNCTION.
Probable Cause: LOSS OF ENGINE POWER DUE TO UNDETERMINED REASONS, AND THE LACK OF A SUITABLE AREA FOR THE FORCED LANDING.
