Probable cause

A failure of the student pilot to conduct an adequate pre-flight inspection to remove contaminated fuel; a failure to maintain adequate airspeed to prevent an inadvertent stall. Contributing to the accident was an inadequate annual inspection of the fuel system to detect a leaking fuel cap, and inadequate supervision of the flight by the pilot-incommand.

Analysis

Prior to the accident flight, the non-certificated student pilot fueled the airplane from a 5-gallon container with automotive fuel. He then invited a certificated pilot to accompany him on a local area flight. Witnesses observed the airplane depart and appeared to climb slowly at a slow airspeed. During a left turn after departure, other witness heard the engine running rough, sputtering, and then quit running. The airplane then banked to the right and descended in a near vertical attitude, striking a cedar tree and mobile home. The airplane was consumed by a post crash fire. Examination of the left fuel tank that was not damaged by fire, revealed the presence of over a quart of water. The interior filler neck and fuel cap had evidence of rust.
