A FACTOR WS THE LACK OF SUITABLE TERRAIN AT THE PILOT'S DISPOSAL FOR THE FORCED LANDING. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, maneuvering - aerial application - reason for occurrence undetermined (cause) - Forced landing, descent - emergency - terrain condition - none suitable (contributing factor) - terrain condition - soft - terrain condition - wet - Nose down, landing - roll - fluid,fuel - fire ## 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 narrative 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. ## Aircraft - Registration: [N8363K](https://openairdocs.org/aircraft/N8363K), registered now, S/N 663B (OpenAirDocs) - Reported make and model: GRUMMAN G-164B - Registry model: [Grumman Acft ENG Cor-Schweizer G-164B](https://openairdocs.org/model/grumman-acft-eng-cor-schweizer-g-164b) (registry code 3952802) (OpenAirDocs) - Category: Airplane - Serial number: 6638 - Airframe hours: 4337 - Engines: P&W PT6A-20B 550 horsepower turbo prop - Damage: Destroyed - Fire: On-Ground - Flight: Aerial application, Part 137 - Registered owner: Farmers Aerial Seeders Corp. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, March 24, 1994, 325 hours before - Departed: NONE, SEATON, AR ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB FTW92LA090](https://openairdocs.org/ntsb/FTW92LA090), Mar 16, 1992: Grumman G-164B (N8363K), Roanoke, LA, substantial damage. Probable cause: THE LOCKING OF THE MAIN LANDING GEAR BRAKES. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
