Although the touchdown in the tailwheel-equipped airplane was uneventful, the pilot applied hard braking in order to minimize the landing roll on the rough terrain. As the airplane began to slow it nosed over coming to rest on its back. Both of the airplane’s wings, the fuselage and the vertical stabilizer and rudder sustained substantial damage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N9211T](https://openairdocs.org/aircraft/N9211T), registered now, S/N 50711, built 1960 (OpenAirDocs) - Reported make and model: CESSNA 180C - Registry model: [Cessna 180C](https://openairdocs.org/model/cessna-180c) (registry code 2072608) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 50711 - Year built: 1960 - Airframe hours: 5067.3 - Engines: Continental 0-470L 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 2, 2021 - Departed: AK06, AK06, AK - Flight plan: Company VFR - Airport: N/A, No ID, runway N/A, gravel - Equipment: Stall warning system ## Flight crew As NTSB recorded them.
