Lycoming Announces Plans to Certify Engines On Mogas

Lycoming aims To Receive Approval For IO/O-360s By Fall 08. Aero-News comments: 'Maybe diesel power isn't the ONLY answer to ever-tightening supplies of 100 low-lead fuel. Recognizing global concerns about the immediate and long-term availability of aviation grade 100LL, on Monday Lycoming Engines announced an unleaded automotive gasoline approval program for its standard compression ratio O-360 and IO-360 product lines. Unleaded 93 AKI automotive gasoline conforming to either Euro Norm EN228 or ASTM D4814 will be the basis of this Lycoming specified fuel. Supplemental requirements within the scope of the existing standards will be stated as necessary for safe operation in aviation applications. Approval is expected by Fall 2008. Lycoming stresses the program will be an engine approval only; aircraft certification approval must be obtained separately to permit operation with this fuel. Lycoming piston engines power more than half of the world's general aviation fleet -- both rotary-wing and fixed-wing. (www.aero-news.net 6/2/08)
DieselAir Comment: Mogas is not available on a vast majority of airfields. We cannot imagine for the long term that small airfields in North America and the world would envision distributing 3 different fuels instead of only one, Jetfuel.
