What happened
Six weeks prior to the accident, the pilot was observed draining approximately one gallon of water from the aircraft's fuel tank. The aircraft remained grounded from that time until the day of the accident. On the day of the event, the pilot and a friend were seen refueling the unspecified aircraft using automobile gasoline.
The engines on this aircraft are not certified by the FAA for use with auto gas. Prior to takeoff, the pilot did not perform a pre-flight inspection or drain the fuel. Shortly after takeoff, at an altitude of approximately 150 feet AGL, both engines failed. Although the pilot had adequate landing options available, the aircraft was slowed in a nose-high attitude until it reached a stall condition. The altitude at which the stall occurred did not permit recovery.
