NTSB narrative
During takeoff from a lake in a float-equipped airplane, the pilot said the airplane became airborne, but the engine began to lose power. The pilot said that he did not think the airplane would clear the trees at the end of the lake, so he started a right turn to stay over the water. As he steepened the turn, the airplane stalled and impacted the lake.
The pilot said the outside temperature was about 55 degrees Fahrenheit and that it was raining. He reported that the more he thought about the circumstances, the more he believed that the loss of power was the result of carburetor ice. The weather conditions at the time of the accident were conducive to serious icing conditions at any engine power setting. No preaccident mechanical problems that would have precluded normal operation were reported.
Probable cause
The pilot’s failure to maintain control of the airplane after a loss of engine power during takeoff due to carburetor ice.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2012-09-03.
