Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) airplanes, that requires, for certain airplanes, a one- time inspection to detect chafing or other damage of the integrated drive generator (IDG) cables and the firewall separators of the pylon, and corrective action if necessary. For other airplanes, this AD requires identification of the part number of the clamps, and replacement with new clamps if necessary. The actions specified by this AD are intended to prevent electrical arcing between the IDG cables and the firewall separators due to chafing, which could result in an in- flight fire and/or loss of electrical power. This action is intended to address the identified unsafe condition.
