## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Bombardier Aerospace has completed a system safety review of the CL-600-2B19 aircraft fuel system * * *. 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. * * *

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
