During a runway change at his home (land) airport, the pilot elected to conduct a water landing to a lake about 12 miles north, during which he inadvertently extended the landing gear on approach and landed on the water with the wheels extended. The airplane immediately nosed over and came to rest inverted in the water, substantially damaging both wings. The pilot did not report any preimpact mechanical malfunctions or failures that would have precluded normal operation. ## Aircraft - Registration: [N1669M](https://openairdocs.org/aircraft/N1669M), registered now, S/N 18501861, built 1971 (OpenAirDocs) - Reported make and model: Cessna A185 (E) - Registry model: [Cessna A185E](https://openairdocs.org/model/cessna-a185e) (registry code 2072818) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18501861 - Year built: 1971 - Airframe hours: 3120 - Engines: Continental IO0520D 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: C Y Transport Llc - Registered owner: C Y Transport Llc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 14, 2020 - Departed: ANE, Minneapolis, MN - Destination: ANE, Minneapolis, MN - Equipment: Auto-pilot, ADS-B, Stall warning system, Satellite tracking device, Onboard weather, Electronic flight bag or handheld device, Electronic primary flight display, Electronic multifunction display ## Flight crew As NTSB recorded them.
