He attempted to perform a go-around, but the right gear door struck an airfield sign. Substantial damage was sustained to the fuselage, empennage, vertical stabilizer, and elevators. The pilot reported no mechanical malfunctions with the airplane. ## Factual narrative According to a statement provided by the pilot, during a landing, the airplane was aligned with the runway when an unexpected wind gust pushed the airplane to the right side of the runway. He attempted to perform a go-around, however the right gear door struck an airfield sign. The pilot then elected to stop and brought the throttle back to idle. The airplane continued through uneven terrain before coming to rest in an upright position. Substantial damage was sustained to the fuselage, empennage, vertical stabilizer, and elevators. The calculated crosswind at the time of the accident was estimated at 17 to 20 knots. The pilot reported no mechanical malfunctions. ## Aircraft - Registration: [N224RG](https://openairdocs.org/aircraft/N224RG), registered now, S/N E-3894, built 2009 (OpenAirDocs) - Reported make and model: HAWKER BEECHCRAFT CORP G36 - Registry model: [Hawker Beechcraft G36](https://openairdocs.org/model/hawker-beechcraft-g36) (registry code 4220009) (OpenAirDocs) - Registry engine: [Continental IO-550-B](https://openairdocs.org/engine/continental-io-550-b) (registry code 17208, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: E-3894 - Airframe hours: 349 - Engines: CONT MOTOR IO-550-B 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Oklahoma Aviation LLC - Registered owner: Striker Management Co LLC - Airworthiness certificate: Standard, Utility - Last inspection: 100 hour, May 12, 2011, 2 hours before - Departed: WWR, Woodward, OK - Destination: KGUY, Guymon, OK - Flight plan: IFR - Airport: KGUY, Guymon Municipal, runway 36, 5,904 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
