A visual flight rules flight plan was filed and the flight was operating on a Special VFR clearance. Instrument meteorological conditions prevailed for Class D airspace. The airplane was substantially damaged and the Pilot-in-Command, the sole occupant, was not injured. According to the Deadhorse Flight Service Station, they had just taken a special weather observation for N734GW and the recorded winds were from 100 degrees magnetic at 30 knots, with gusts to 46 knots. According to the Deadhorse Flight Service Station radio transmission transcripts, N734GW was given winds as "Zero Six Zero at three five gust four three", just prior to landing. According to the Pilot-in-Command, as soon as he turned onto the mid-field taxiway and was subjected to a crosswind, the airplane nosed over. Toxicological results were negative. The Pilot-in-Command reported no mechanical problems with the airplane prior to the mishap. ## Aircraft - Registration: [N734GW](https://openairdocs.org/aircraft/N734GW), registered now, S/N U20604832, built 1978 (OpenAirDocs) - Reported make and model: CESSNA 206 - Registry model: [Cessna U206G](https://openairdocs.org/model/cessna-u206g) (registry code 2073356) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U20604832 - Engines: CONTINENTAL IO-520-F 300 horsepower reciprocating - Damage: Substantial damage - Flight: Part 91 - Operator: 40 Mile Air, Ltd - Registered owner: 40 Mile Air, Ltd - Airworthiness certificate: Standard, Normal - Last inspection: Continuous airworthiness, April 9, 1993, 60 hours before - Departed: AK71, LONELY, AK - Flight plan: VFR - Airport: SCC, Deadhorse, runway 4, 6,499 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
