The pilot reported that during a landing to a lake in Hartland, Maine, the float-equipped Cessna 180 hit the water, porpoised, and flipped over.
The pilot reported the plane “flipped over like a ground loop” and subsequently sustained substantial damage to the left wing.
The pilot reported no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
Probable cause: Abnormal runway contact, which precipitated a loss of control and nose-over.
