The NTSB's narrative final · quoted from the NTSB record
The aircraft had been airborne for 30 minutes cruising at 4,500 feet msl when it lost fuel pressure and engine power, and ditched in the ocean. The aircraft was not recovered. The pilot reported they departed with 30 plus gallons of automotive gasoline for the 130 mile trip. According to the engine manufacturer this engine was designed for a minimum of 91/96 aviation grade fuel. There are FAA Supplemental Type Certificates for the use of automobile gasoline in this engine with requirements to verify the specifications of the auto gas being used, and information about the increased tendency for carburetor icing and vapor generation with its use. The aircraft records were obtained from FAA Oklahoma City, and no record of approval for the use of automobile gasoline via FAA form 337 was found.
