Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
This AD applies to Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certified in any category, serial numbers 7003 through 7067 and 7069 through 7797.
We are adopting a new airworthiness directive (AD) for the products listed above. This 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:
Unless already done, do the following actions.
(1) Within 5,000 flight hours after the effective date of this AD, carry out a detailed inspection for the presence of an anodized (blue color) fuel boost pump reducer coupling according to the Accomplishment Instructions of Bombardier Service Bulletin 601R-28-057, dated December 4, 2003.
(2) If the results of the inspection required by paragraph (f)(1) of this AD reveal that none of the fuel boost pump reducer couplings are anodized, no further action is required.
(3) If the results of the inspection required by paragraph (f)(1) of this AD reveal the presence of any anodized fuel boost pump reducer coupling, prior to further flight, replace the anodized coupling with a coupling having ion vapor deposition coating according to the Accomplishment Instructions of Bombardier Service Bulletin 601R-28-057, dated December 4, 2003.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
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.
