This AD results from a report that Gask-O-Seals that did not incorporate an integral restrictor to limit fuel flow rate and fuel pressure during refueling were installed on certain airplanes. We are issuing this AD to prevent a buildup of excessive static charge, which could create an ignition source inside the fuel tank.
