The float-equipped airplane inadvertently contacted the water and bounced twice on the surface. The pilot lost directional control and nosed over which resulted in substantial damage to the right wing and vertical stabilizer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N3495L](https://openairdocs.org/aircraft/N3495L), registered now, S/N U206-0795, built 1967 (OpenAirDocs) - Reported make and model: CESSNA U206B - Registry model: [Cessna U206B](https://openairdocs.org/model/cessna-u206b) (registry code 2073322) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U206-0795 - Year built: 1967 - Airframe hours: 4937 - Engines: Continental I0520F9 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Saqul'Aq Air LLC - Airworthiness certificate: Standard, Utility - Last inspection: Annual, October 21, 2022, 11 hours before - Departed: AUO, Willow, AK - Destination: Same as departure - Equipment: ADS-B, Handheld GPS, Stall warning system ## Flight crew As NTSB recorded them.
