As he pushed the right rudder to make a right turn, the airplane continued straight ahead up an embankment. The pilot reported that there were no mechanical problems with the flight controls. A postaccident examination revealed that the airplane had come to rest on a 10-degree slope with damage to the horizontal stabilizer. No mechanical anomalies with the braking and steering systems were found. ## Factual narrative According to the pilot's written statement, after exiting the runway, he proceeded to taxi the airplane to parking. As he pushed the right rudder to make a right turn, the airplane continued straight ahead up an embankment. The pilot reported that there were no mechanical problems with the flight controls. A Federal Aviation Administration (FAA) airworthiness inspector responded to the site and reported that the airplane had come to rest on a 10-degree slope with damage to the horizontal stabilizer. He also inspected the braking and steering system and found no mechanical anomalies. ## Aircraft - Registration: [N3723D](https://openairdocs.org/aircraft/N3723D), registered now, S/N 34423, built 1957 (OpenAirDocs) - Reported make and model: CESSNA 182A - Registry model: [Cessna 182A](https://openairdocs.org/model/cessna-182a) (registry code 2072704) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 34423 - Airframe hours: 6318 - Engines: CONT MOTOR O-470 SERIES 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: John Olsen - Registered owner: Olsen'S Grain Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 1, 2011, 6 hours before - Departed: IGM, Kingman, AZ - Destination: PRC, Prescott, AZ - Airport: PRC, Ernest A.
