N8363K

GRUMMAN G-164B

Analysis

THE COMMERCIAL PILOT REPORTED A 'LOUD CANNON-LIKE SOUND' COMING FROM THE ENGINE, FOLLOWED BY A COMPLETE LOSS OF ENGINE POWER. DURING THE FORCED LANDING ROLLOUT IN A SOFT FIELD, THE MAIN LANDING GEAR SANK INTO THE SOFT GROUND, AND THE AIRPLANE CAME TO REST WITH THE PROPELLER SPINNER STUCK IN THE GROUND. FUEL FROM THE FUEL TANK ON THE TOP WING DRIPPED DOWN THE COWLING INTO THE ENGINE COMPARTMENT, STARTING A FIRE. A POST-IMPACT FIRE DESTROYED THE AIRPLANE. A DETAILED ENGINE EXAMINATION AND TEARDOWN FAILED TO DISCLOSE ANY ANOMALIES THAT WOULD HAVE PREVENTED NORMAL ENGINE OPERATION.

Factual Information

On June 6, 1994, at 1030 central daylight time, a Grumman G-164B, N8363K, was destroyed during a forced landing near Carlisle, Arkansas. The commercial pilot was not injured. Visual meteorological conditions prevailed for the aerial application flight. According to the pilot, the airplane was dispensing fertilizer on an easterly heading at an altitude of 50 feet AGL, near the end of the rice field. The pilot further reported hearing a "loud cannon-like pop sound" coming from the engine, immediately followed by the complete loss of engine power. The pilot added that at the point of the power loss, a line of tall trees was less than 1/8 of a mile ahead of the airplane. He elected to turn right into the wind while attempting to dump his load from the 400 gallon hopper. The spreader assembly separated from the fuselage on initial contact with the ground. As the main landing gear sank into the soft muddy ground, the airplane went nose down and came to rest with the propeller spinner stuck in the ground. According to the pilot's enclosed statement, fuel from the 97 gallon fuel tank on the top wing dripped down the cowling and into the engine compartment, starting a fire. Post-impact fire destroyed the airplane. A detailed examination and teardown of the engine failed to disclose any anomalies that would have prevented normal engine operation.

Probable Cause and Findings

THE LOSS OF ENGINE POWER FOR UNDETERMINED REASON. A FACTOR WS THE LACK OF SUITABLE TERRAIN AT THE PILOT'S DISPOSAL FOR THE FORCED LANDING.
