On May 14, 1994, a Cessna 175 (registration N7678M) was involved in an aviation accident near Plainfield, IL. Investigators recorded the probable cause as: The pilot's failure to ensure the fuel system was free of contamination, which resulted in an engine failure during climbout and a subsequent off-airport forced landing. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot practicing touch-and-go landings experienced an engine failure during climbout, resulting in a forced off-airport landing and a nose-over. Investigation revealed water contamination in the carburetor bowl and right fuel tank.
What happened
The pilot was conducting local pattern work, specifically practicing touch-and-go landings. After completing several such maneuvers, the engine quit during the climbout phase of one of the cycles. The pilot initiated an off-airport forced landing. During the impact with the ground, the airplane nosed over.
Findings
Post-accident examination revealed significant fuel system contamination. The carburetor bowl was found to contain a mixture of fuel and water. Additionally, water was discovered in the right fuel tank. This contamination likely led to fuel starvation or engine malfunction during the critical climbout phase.
Probable cause
The pilot's failure to ensure the fuel system was free of contamination, which resulted in an engine failure during climbout and a subsequent off-airport forced landing.
