On October 11, 1992, a Cessna 210F (registration N1840F) operated by Child, Michael T was involved in an aviation accident near Buena Park, CA. Investigators recorded the probable cause as: FAILURE OF THE PILOT TO ADEQUATELY DETECT WATER CONTAMINATION IN THE AIRPLANE'S FUEL SYSTEM DURING PREFLIGHT. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a maintenance test flight after an annual inspection and cylinder replacement, the engine lost power shortly after takeoff. The pilot performed a forced landing on a highway, colliding with two moving vehicles. Water was found in the cylinders, and the aircraft had been stored for months with fuel tanks not topped off.
Incident Overview
A pilot was conducting a maintenance test flight following an annual inspection and the replacement of two cylinders. Shortly after takeoff, the engine lost power, necessitating an immediate forced landing. The pilot chose a highway as the landing site, where the airplane subsequently collided with two moving motor vehicles.
Post-Incident Examination
Examination of the engine revealed evidence of water in the cylinders. The aircraft had been sitting for several months without the fuel tanks topped off, which may have contributed to water contamination.
Investigation Findings
The investigation confirmed the presence of water in the engine cylinders. The aircraft's prolonged storage with fuel tanks not fully filled is consistent with conditions that could allow moisture accumulation. No other mechanical anomalies were reported. The forced landing and subsequent collision with vehicles on the highway were a direct result of the engine power loss.
