However, the flight instructor elected to demonstrate a soft field touch-and-go landing on the snow-covered runway before the return flight. When the airplane touched down, the snow was deeper than the flight instructor anticipated, and the airplane slowed faster than he expected. The pilots added full power and increased back pressure on the control yoke; however, the airplane pitched forward on its nosewheel and then rolled right and left, striking both wings and substantially damaging both main wing spars. The pilots reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative After conducting a low pass over the runway to judge the height of the snow, the flight instructor elected to demonstrate a soft field touch-and-go landing. When the airplane touched down, the snow height was greater than he anticipated and the airplane slowed faster than he expected. Full power was applied and the airplane pitched forward. The airplane continued forward on its nose wheel and rolled to the right and left, striking both wings on the ground which substantially damaged both main wing spars. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N58677](https://openairdocs.org/deregistered/N58677-2014-10-30), registration cancelled 2014-10-30, S/N 18262228, built 1973 (OpenAirDocs) - Reported make and model: CESSNA 182P - Registry model: [Cessna 182P](https://openairdocs.org/model/cessna-182p) (registry code 2075816) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18262228 - Airframe hours: 3997 - Engines: CONT MOTOR O-470 SERIES 230 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Pacific Aviation Northwest Inc - Registered owner: Robert Watson - Airworthiness certificate: Standard, Normal - Last inspection: Annual, September 28, 2012, 18 hours before - Departed: 3S8, Grants Pass, OR - Destination: 2S7, Chiloquin, OR - Airport: 2S7, Chiloquin State Airport, runway 35, 3,749 × 60 ft, snow ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
