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 onto its back. Both the wings and the fuselage sustained substantial damage. The pilot reported that there were no mechanical problems with the airplane's systems. ## Factual narrative The pilot, who was on a local area personal flight, decided to make an off-airport landing in an open field. 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 onto its back. Both the wings and the fuselage sustained substantial damage. The pilot reported that there were no mechanical problems with the airplane's systems. In the recommendations section of the NTSB Form 6120.1, he stated that landings requiring higher demands than the pilot's current skill level should not be attempted. ## Aircraft - Registration: [N1705N](https://openairdocs.org/deregistered/N1705N-2017-10-20), registration cancelled 2017-10-20, S/N 11949, built 1946 (OpenAirDocs) - Reported make and model: CESSNA 120 - Registry model: [Cessna 120](https://openairdocs.org/model/cessna-120) (registry code 2071402) (OpenAirDocs) - Registry engine: [Continental C85 series](https://openairdocs.org/engine/continental-c85-series) (registry code 17008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 11949 - Airframe hours: 2600 - Engines: CONT MOTOR C85 SERIES 85 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Mayfield Bruce J - Registered owner: Mayfield Bruce J - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 28, 2011 - Departed: KPDT, Pendleton, OR - Destination: KPDT, Pendleton, OR ## Flight crew As NTSB recorded them.
