on 22 November 2007.
Background:  Bombardier Aerospace has completed a system safety review of the CL-600-2B19 aircraft fuel system against new fuel tank safety standards.

             The assessment showed that sealant has not been applied to bolts on the collector fuel tanks or the transfer ejector fuel pumps.  Lack of sealant on the above-noted locations, if not corrected, could result in arcing and potential ignition source inside the fuel tank during lightning strikes and consequent fuel tank explosion.  To correct the unsafe condition, this AD mandates the application of sealant to the bolts that attach various fittings on the collector fuel tanks, to the edges of the transfer ejector pumps and to the bolts that attach the transfer ejector pump to the transfer ejector pump casing.
