Aircraft: Cessna 150. Location: Flora, Miss. Injuries: None. Aircraft damage: Substantial.
What reportedly happened: A student pilot and flight instructor were practicing forced landings. During a go-around from a simulated forced landing, the airplane experienced a total loss of engine power. Low altitude precluded an engine restart and the flight instructor elected to conduct a forced landing in a nearby corn field.
Unable to align with the plowed rows, the CFI landed perpendicular to the rows and subsequently nosed over. Analysis of the engine revealed fuel contaminated with water in the gascolator and carburetor bowl. Both components were properly sealed to prevent water intrusion.
The flight instructor reported that no water was found in the fuel during the preflight inspection. However, he speculated that a sideslip performed during the simulated engine failure may have allowed water to pool in the fuel tanks and caused engine stoppage.
Probable cause: Loss of engine power due to fuel contamination.
