During the second bounce, he applied full back stick pressure to place the tailwheel on the ground. Aileron and directional control inputs were applied to counteract the gusting crosswind, but the airplane veered right, exited the runway, and ground looped. The airplane sustained substantial damage to the left wing, horizontal stabilizer, and elevator. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that during landing in the tailwheel equipped airplane with a crosswind, the airplane touched down on the main wheels and bounced. During the second bounce he applied full back stick pressure to place the tailwheel on the ground. Aileron and directional control inputs were applied to counteract the gusting crosswind, but the airplane veered right, exited the runway and ground looped. The airplane sustained substantial damage to the left wing, horizontal stabilizer and elevator. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station located on the airport reported that, about the time of the accident, the wind was from 280° at 11 knots, gusting 14 knots. The airplane landed on runway 20. ## Aircraft - Registration: [N9235B](https://openairdocs.org/aircraft/N9235B), registered now, S/N 55035, built 1958 (OpenAirDocs) - Reported make and model: Cessna 175 (Undesignat) - Registry model: [Cessna 175](https://openairdocs.org/model/cessna-175) (registry code 2072502) (OpenAirDocs) - Registry engine: [Continental GO-300 series](https://openairdocs.org/engine/continental-go-300-series) (registry code 17024, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 55035 - Year built: 1958 - Engines: Lycoming O-360-A1A 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Inceptus Inc - Registered owner: Inceptus Inc - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, June 27, 2019 - Departed: COE, Coeur d'Alene, ID - Destination: COE, Coeur d'Alene, ID - Airport: COE, Coeur d'Alene Airport, runway 20, 5,400 × 75 ft, asphalt - Equipment: None ## Flight crew As NTSB recorded them.
