The float-equipped airplane sustained substantial damage at about 1415 Alaska time when it impacted the water during takeoff. Visual conditions prevailed; the solo pilot received serious injuries.
During takeoff, the airplane became airborne, but the pilot did not think he would clear trees at the end of the lake. He started a right turn to stay over the water, but as the turn steepened, the airplane stalled and impacted the lake. He said he did not know if the airplane’s engine was producing full power. The right wing of the airplane was severed.
