The pilot said that when the airplane touched down on the runway it veered to the left, and that he applied full right rudder and aileron, and then applied full power to abort the landing. He reported that the airplane exited the runway to the left and impacted terrain. The pilot said that there were no known mechanical problems with the airplane prior to the accident and that prior landings that day were uneventful. He said that the airplane sustained damage to the wings and fuselage. ## Factual narrative On July 29, 2008, about 1420 Alaska daylight time, a Cessna 207 airplane, N9952M, sustained substantial damage when it collided with terrain following an aborted landing at the Quinhagak Airport, Quinhagak, Alaska. The airplane was being operated by Grant Aviation, Anchorage, Alaska, as a visual flight rules (VFR) positioning flight under Title 14, CFR Part 91, when the accident occurred. The solo airline transport pilot was not injured. Visual meteorological conditions prevailed, and company flight following procedures were in effect. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on July 30, the pilot said as the airplane touched down on the runway, it veered to the left. He said he applied full right rudder and aileron, then applied full power to abort the landing, but the airplane exited the runway to the left and impacted terrain. The pilot said there were no known mechanical problems with the airplane prior to the accident, and that prior landings that day were uneventful. He said the airplane sustained substantial damage to the wings and fuselage. ## Aircraft - Registration: [N9952M](https://openairdocs.org/aircraft/N9952M), registered now, S/N 207-00345, built 1976 (OpenAirDocs) - Reported make and model: CESSNA 207 - Registry model: [Cessna 207](https://openairdocs.org/model/cessna-207) (registry code 2073602) (OpenAirDocs) - Category: Airplane - Serial number: 207-00345 - Airframe hours: 21462 - Engines: Continental IO-520-F 300 horsepower reciprocating - Damage: Substantial damage - Flight: Positioning, Part 91 - Operator: Grant Aviation, doing business as Grant Aviation - Registered owner: Alaska Aircraft Leasing LLC - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, July 29, 2008 - Departed: PABE, Goodnews Bay, AK - Destination: PAQH, Quinhagak, AK - Flight plan: Company VFR - Airport: AQH, Quinhagak, runway 30, 4,000 × 75 ft, gravel ## Flight crew As NTSB recorded them.
