On May 10, 2001, a Champion 7EC (registration N4737E) was involved in an aviation accident near Monson, ME. Investigators recorded the probable cause as: The pilot's inadequate aircraft preflight inspection, which resulted in a total loss of engine power during climb due to fuel contamination. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A floatplane experienced a total loss of engine power during climb after winter storage. The pilot had not checked fuel samples for contamination. FAA inspection revealed visible contamination in the gascolator.
Preflight and Departure
Prior to the accident flight, the floatplane had been in storage during the winter season. The pilot reported that during the preflight inspection, he checked the fuel and oil quantity but did not examine any fuel samples for contamination. The pilot then started the engine and allowed it to idle for approximately 10 minutes before departing from the pond.
Engine Failure and Forced Landing
During the climb after departure, the engine lost all power. The pilot subsequently performed a forced landing into trees. No additional details regarding the outcome of the landing were provided in the source.
Post-Accident Examination
An examination of the wreckage was conducted by a Federal Aviation Administration inspector. The inspection revealed approximately 2 tablespoons of visible contamination present in the gascolator.
