General Aviation Modifications Inc. (GAMI) says it will issue a detailed response to Cirrus Aircraft’s recent service advisory discouraging the use of GAMI’s G100UL unleaded fuel in its SR series aircraft.

In a statement to AVweb, GAMI said the service advisory appears to be linked to a single incident in which the sealant used in the fuel tank had unbonded in a company aircraft that had been fueled with G100UL. GAMI says there are indications the unbonded sealant had nothing to do with the fuel, but because the tank was not inspected before the unleaded fuel was introduced there’s no way to prove whether the fuel was a factor.
