Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires replacing the Gask-O-Seal in the coupling of the refuel/defuel shut-off valves. 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.
