During takeoff roll in gusty crosswind conditions, the pilot lost directional control, departed the right side of the runway, and struck a taxiway lip. The aircraft became airborne, hit a fence, and flipped inverted into a lake. Both occupants exited and swam to shore.

Accident Sequence

During the takeoff roll, the aircraft was subjected to gusty crosswind conditions. The pilot failed to maintain directional control, causing the aircraft to veer off the right side of the runway. The pilot did not reduce engine power, and the aircraft continued across a grassy area situated between the runway and an adjacent taxiway. As the aircraft traversed this area, its landing gear struck the raised edge of the taxiway, causing the aircraft to become airborne. After becoming airborne, the aircraft struck a chain-link fence and subsequently flipped inverted, coming to rest in a lake that borders the airport. Both the pilot and a passenger were able to exit the overturned aircraft through the side windows and swam to the shore.
