After engine start, warm up, and taxi, he began his takeoff roll from the lake. The pilot said the airplane took longer than normal to take off and once he was airborne his airspeed was only about 40-45 miles per hour. When he lowered the nose of the airplane to gain airspeed, the “right wing started to wave up and down,” consistent with a stall. The pilot attempted to land straight ahead on the lake, but upon touchdown, the right wing impacted the water, spinning the airplane, and collapsing the right float. During the impact sequence the outboard portion of the left wing was impact-separated, resulting in substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. Therefore, it is most likely that the pilot did not obtain the proper airspeed or angle of attack on takeoff, which resulted in an aerodynamic stall and subsequent loss of control. ## Aircraft - Registration: [N5625T](https://openairdocs.org/aircraft/N5625T), registered now, S/N 207, built 2007 (OpenAirDocs) - Reported make and model: REMOS AIRCRAFT GMBH GEMINI REMOS G-3/600 - Registry model: [Remos GEMINI REMOS G-3/600](https://openairdocs.org/model/remos-gemini-remos-g-3-600) (registry code 0600039) (OpenAirDocs) - Registry engine: [Rotax 912ULS series](https://openairdocs.org/engine/rotax-912uls-series) (registry code 55572, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 207 - Year built: 2007 - Airframe hours: 1881 - Engines: Rotax 912ULS 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Fred Northup - Registered owner: 5625t LLC - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: Condition, September 12, 2024, 6 hours before - Destination: 6B4, Utica/Frankfort, NY - Equipment: Electronic multifunction display, Electronic flight bag or handheld device, Angle of attack indicator, ADS-B, Stall warning system, Satellite tracking device, 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.
