The power line was a factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, maneuvering - aerial application - object - wire,transmission (contributing factor) - clearance - not maintained, pilot in command (cause) ## Analysis During an aerial application spray run, the aircraft collided with a power line on the northeast corner of the field. After the collision, the engine lost power and the pilot initiated a forced landing in a nearby field. During the landing roll, the aircraft collided with several small trees before coming to rest. The pilot stated that he was aware of the location of the power lines before he began the spray run. ## Factual narrative On September 27, 2000, at 1430 Pacific daylight time, an Air Tractor AT-602, N5111A, registered to and operated by Weaver Flying Service as a 14 CFR Part 137 aerial application flight, collided with power lines and subsequently the terrain near Columbia River, Washington. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft was substantially damaged and the commercial pilot, the sole occupant, was not injured. The flight originated from a private airstrip in Quincy, Washington, about 15 minutes prior to the accident. In a written statement, the pilot reported that he over flew the area to be sprayed to check for people, obstacles and the wind condition. The pilot stated that he noted the powerlines on the northeast side of the field and trees running east/west on the north end. The pilot made the first spray pass to the north, on the east side of the field, paralleling smaller power lines. When the pilot pulled up on the north end of the field, the aircraft collided with the powerlines in the northeast corner of the field. The engine began to lose oil and power. The pilot then maneuvered the aircraft for a forced landing in an apple orchard. The aircraft collided with several small apple trees before coming to rest. ## Aircraft - Registration: [N5111A](https://openairdocs.org/aircraft/N5111A), registered now, S/N 602-0427, built 1997 (OpenAirDocs) - Reported make and model: Air Tractor AT-602 - Registry model: [Air Tractor AT-602](https://openairdocs.org/model/air-tractor-at-602) (registry code 0390309) (OpenAirDocs) - Registry engine: [Pratt & Whitney Canada PT6A-66 series](https://openairdocs.org/engine/pratt-whitney-canada-pt6a-66-series) (registry code 52118, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: 602-0427 - Airframe hours: 1942 - Engines: P&W PT6A-65 1300 horsepower turbo prop - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Weaver Flying Service - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, April 25, 2000, 423 hours before - Departed: 80WA, QUINCY, WA ## Flight crew As NTSB recorded them.
