New Unleaded Avfuel Approved for use by EAA Supplemental Type Certificate Holders

EAA, The Leader in Recreational Aviation, is issuing a service bulletin to the thousands of aircraft owners who hold EAA Supplemental Type Certificates (STCs), permitting use of auto fuel in their aircraft's powerplants and airframes. That bulletin is being issued after the Federal Aviation Administration (FAA) approved the introduction of unleaded 82UL aviation fuel.

The 82UL avfuel qualifies under the specifications allowed under EAA's STC. FAA approved the inclusion of this fuel in the STCs because of EAA's extensive testing with auto fuels and the new 82UL, including in such vital areas as volatility. 82UL has a lower volatility requirement than auto fuel, which would put it well within the limits covered by EAA's STC.

"The new unleaded fuel is part of the effort to remove leaded fuels from aircraft use, mostly because of environmental reasons," said Earl Lawrence, EAA Vice President of Government Relations. "Around the world, nations have banned or are banning the sale of leaded fuels. Therefore, refiners are eliminating or reducing production of those fuels. EAA has been extensively involved in the development of 82UL, so that pilots of smaller aircraft would have an unleaded option as the fuels are developed."

EAA's service bulletin reminds STC holders that current fueling placards must be replaced by Aug. 1, 2000, with revised placards which remind aircraft fuelers of allowable fuels for those airplanes. The placards, which cost $5.00 each (including shipping), are available through EAA by calling 920-426-4843 or via e-mail at STC@eaa.org. The full text of FAA's Special Airworthiness Information Bulletin will be posted as soon as it is published.
