CubCrafters can run on auto fuel

June 4, 2010

Top CubCubCrafters has received a supplemental type certificate (STC) for its Part 23 certified Top Cub. The auto fuel STC is available from Petersen Aviation and is approved for all CC18-180/CC18-180A aircraft.

An approved mechanic must “install” the STC by adding the new fuel and engine placards, and then fill out a logbook entry and FAA form 337. The process takes approximately 30 minutes. No additional modification is required.

The STC allows the use of ethanol-free fuel with a minimum octane rating of 91. Installing the auto fuel STC does not restrict the aircraft to using only auto fuel. Aviation gas can still be used, or can be mixed with auto fuel.

“The auto fuel option will open up even more remote destinations that, until now, have been inaccessible because of the lack of easy access to fuel,” said CubCrafters owner and chairman Jim Richmond. “In addition, it will let Top Cub pilots keep more of their hard-earned money in their pockets.”

The Top Cub can be ordered with optional tundra tires.
