A contributing factor was the lack of suitable terrain 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, emergency descent/landing - Nose over, landing - roll - terrain condition - none suitable (contributing factor) - terrain condition - drop-off/descending embankment ## Analysis According to the pilot, the agricultural airplane was in a turn for the second pass over a field when the engine started to 'flutter and lose power.' The pilot applied full power on the engine controls; however, the engine tachometer indicated approximately 1,500-1,600 RPM. The pilot dumped the load and set up for a forced landing in the field. Upon touchdown, the airplane approached a slope in the field and nosed over, coming to rest inverted. The reason for the loss of engine power was undetermined. ## Factual narrative On September 7, 2000, at 0815 central daylight time, a Grumman-Schweizer G-164B agricultural airplane, N8255K, was substantially damaged when it nosed over during a forced landing following a loss of engine power near Erick, Oklahoma. The airplane was registered to and operated by James Aerial Spraying of Sayre, Oklahoma. The commercial pilot, who was the sole occupant, was not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 137 aerial application flight. The local flight originated from the Sayre Municipal Airport at 0800. During a telephone interview conducted by the NTSB investigator-in-charge, the pilot stated that he was in a turn for the second pass over a field when the engine started to "flutter and lose power." The pilot added that he applied full power on the engine controls; however, the engine tachometer indicated approximately 1,500-1,600 RPM. The pilot dumped the load and set up for a forced landing in the field. Upon touchdown, the airplane approached a slope in the field, nosed over, and came to rest inverted. The empennage was structurally damaged. The reason for the loss of engine power was undetermined. ## Aircraft - Registration: [N8255K](https://openairdocs.org/deregistered/N8255K-2001-11-01), registration cancelled 2001-11-01, S/N 637B (OpenAirDocs) - Reported make and model: Grumman-Schweizer 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: 637B - Airframe hours: 7627 - Engines: P&W R-1340 AN-1 600 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: James Aerial Spraying - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Continuous airworthiness, September 1, 2000, 5 hours before - Departed: OK23, SAYRE, OK ## Flight crew As NTSB recorded them.
