NTSB Factual Report

The pilot of the homebuilt Falco F8L reported that he drained three to four cups of water from the airplane's fuel system prior to takeoff. During the initial climb after takeoff, the engine began to run rough and lose power. During the ensuing forced landing, the airplane impacted the ground and was substantially damaged. The pilot reported that the airplane had been parked outside the week prior to the flight, during abnormally high rainfall. The pilot also said he was not sufficiently careful in draining the airplane's fuel tank. Examination of the airplane did not reveal any pre-impact mechanical malfunctions.

NTSB Probable Cause

The pilot's inadequate pre-flight inspection, which resulted in a loss of engine power due to fuel contamination.
