On December 9, 1989, a Cessna 172G (registration N4289L) operated by Charles E. Michaud was involved in an aviation accident near Uxbridge, MA. Investigators recorded the probable cause as: A large piece of ice blocking the fuel strainer, reducing fuel flow by at least 50%. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a flight, the pilot experienced engine roughness after 35 minutes and applied carburetor heat without effect. While attempting a forced landing in an industrial park, the engine quit, and a steep bank to avoid a powerline resulted in a stall and ground impact. Post-accident examination revealed a large piece of ice attached to the fuel strainer, blocking at least 50% of fuel flow.
Accident Narrative
The pilot reported that fuel tanks were full before departure. Approximately 35 minutes into the flight, the engine began to run rough. The pilot applied carburetor heat, but the engine did not respond. He then attempted to land in an industrial park but found himself too high. During maneuvering, the engine quit entirely. To avoid hitting a powerline, the pilot executed a steep bank to the right. The airplane subsequently stalled and struck the ground.
Post-Accident Examination
After the accident, investigators examined the engine and fuel system. A large piece of ice was found attached to the fuel strainer. The ice was of sufficient size to block at least 50% of the fuel flow, which likely caused the engine power loss.
Probable cause
A large piece of ice blocking the fuel strainer, reducing fuel flow by at least 50%.
