Incident Overview
A pilot operating a newly purchased float plane experienced an engine power loss while flying over level, tree-covered terrain with no clearings. The aircraft was substantially damaged during a forced landing in a wooded area. The pilot had checked the fuel before departing Smith Pond, Maine, estimating 30 to 40 gallons on board.
Flight Sequence
The pilot flew from Smith Pond to Waterville, then to Katahdine Lake. While on the next leg of the flight, the engine lost power. The pilot switched fuel tanks, and the engine restarted for a few seconds before losing power again. The flight had covered approximately 216 miles since departure, with an estimated cruise speed of 110 mph with floats. In-flight fuel flow meter readings indicated about 15 gallons per hour.
Post-Accident Findings
The pilot reported that the fuel gauges indicated full at the time of the accident and suspected a problem with the fuel tank vents. However, an inspection of the vents revealed they were clean and showed no signs of blockage. The engine underwent an operational check on May 27, 1982, and ran satisfactorily.
