Airworthiness Directive · Amendment 39-10294 · Bombardier Model CL-600-1A11 and CL- 600-2A12 Series Airplanes
Bombardier Model CL-600-1A11 and CL- 600-2A12 Series Airplanes
Model CL-600-1A11 series airplanes, as listed in Bombardier Canadair Challenger Alert Service Bulletin A600-0644, Revision 01, dated March 31, 1995; and Model CL-600-2A12 series airplanes, as listed in Bombardier Canadair Challenger Alert Service Bulletin A601-0441, Revision 01, dated March 31, 1995; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-1A11 and CL-600-2A12 series airplanes, that requires replacement of the anti-noise filter on the standby and auxiliary power unit (APU) fuel pump assemblies with a new filter. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent electrical arcing between the internal wiring and casing of the anti- noise filter on the standby and APU fuel pump assemblies, and consequent increased risk of fuel tank explosion or fire.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
