After refueling, he departed the airport but neglected to retract the landing gear and he flew back to the same lake. During the touchdown, the float plane nosed over, and the engine truss was substantially damaged. The pilot added that he would modify his takeoff and prelanding checklist procedure to better verify the configuration of the landing gear. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe and engine that would have precluded normal operation. ## Aircraft - Registration: [N856TC](https://openairdocs.org/aircraft/N856TC), registered now, S/N 100-0041, built 2010 (OpenAirDocs) - Reported make and model: Quest KODIAC 100 (No Series) - Registry model: [Quest KODIAK 100](https://openairdocs.org/model/quest-kodiak-100) (registry code 7320001) (OpenAirDocs) - Registry engine: [Pratt & Whitney Canada PT6A-34 series](https://openairdocs.org/engine/pratt-whitney-canada-pt6a-34-series) (registry code 52250, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: 100-0041 - Year built: 2010 - Airframe hours: 504 - Engines: Pratt & Whitney PT6-344 750 horsepower turbo prop - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Cly Aviation Llc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 28, 2020, 6 hours before - Departed: KBFI, Seattle, WA - Destination: Same as departure - Airport: WA32, Seaplane Scenics Carillon Point - Equipment: Electronic primary flight display, Electronic multifunction display, Auto-pilot, ADS-B, Stall warning system, Onboard weather ## 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.
