Despite the pilot’s control inputs, the airplane continued to veer to the right, exited the runway surface, and came to rest nose down on soft terrain. The pilot initially reported that the airplane’s brakes were operating incorrectly; however, he later reported that there was nothing wrong with the brakes. Examination of the airplane revealed that the landing gear box sustained substantial damage. Further examination of the braking system revealed no mechanical anomalies that would have precluded normal operation. ## Factual narrative During landing roll, the pilot applied brakes and the tailwheel equipped airplane veered to the right. Despite the pilot’s control inputs, the airplane continued to veer to the right, exited the runway surface, and came to rest nose low on soft terrain. The pilot initially reported that the airplane’s brakes were operating incorrectly; however, he later reported to a Federal Aviation Administration (FAA) inspector that there was nothing wrong with the brakes. Examination of the airplane by an FAA inspector revealed that the landing gear box sustained substantial damage. Further examination of the braking system revealed no mechanical anomalies that would have precluded normal operation. ## Aircraft - Registration: [N5351D](https://openairdocs.org/aircraft/N5351D), registered now, S/N 50249 (OpenAirDocs) - Reported make and model: CESSNA 180A - Registry model: [Cessna 180A](https://openairdocs.org/model/cessna-180a) (registry code 2072604) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 50249 - Airframe hours: 2600 - Engines: CONT MOTOR O-470 SERIES 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Splan Dave - Registered owner: Splan Dave - Airworthiness certificate: Standard, Normal - Departed: Moose Creek, ID - Destination: U70, Cascade, ID - Airport: U70, Cascade Airport, runway 30, 4,300 × 60 ft, asphalt ## Flight crew As NTSB recorded them.
