Airworthiness Directive · Amendment 39-15840 · Fuel
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, serial numbers 7003 through 7067, and 7069 through 7929, certificated in any category.
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: Within 5,000 flight hours after the effective date of this AD, do the following actions.
(1) For airplanes on which none of the Bombardier service bulletins identified in Table 1 of this AD have been incorporated as of the effective date of this AD: Modify the fuel tank bonding jumpers inside the wing and center fuel tanks in accordance with Part A of the Accomplishment Instructions of Bombardier Service Bulletin 601R-28-055, Revision F, dated May 27, 2008.
| Bombardier service bulletin— | Revision— | Dated— |
|---|---|---|
| 601R-28-055 | Original | May 4, 2004. |
| 601R-28-055 | A | February 14, 2005. |
| 601R-28-055 | B | September 14, 2005. |
| 601R-28-055 | C | January 9, 2006. |
(2) For airplanes on which any Bombardier service bulletin identified in Table 1 of this AD has been incorporated as of the effective date of this AD: Do a general visual inspection of the inside of the wing and center fuel tanks to determine if the actions in Part A of the Accomplishment Instructions of Bombardier Service Bulletin 601R-28-055, Revision F, dated May 27, 2008, have been done on both sides of the airplane. If Part A of Bombardier Service Bulletin 601R-28-055, Revision F, dated May 27, 2008, has not been done on either side of the airplane, before further flight, do the actions specified in Part A of the Accomplishment Instructions of Bombardier Service Bulletin 601R-28-055, Revision F, dated May 27, 2008; for the side of the airplane on which Part A of Bombardier Service Bulletin 601R-28-055, Revision F, dated May 27, 2008, has not been done.
(3) Actions done before the effective date of this AD in accordance with Bombardier Service Bulletin 601R-28-055, Revision D, dated July 17, 2006; or Bombardier Service Bulletin 601R-28-055, Revision E, dated March 17, 2008; is acceptable for compliance with the corresponding requirements of this AD.
Note 1: This AD differs from the MCAI and/or service information as follows: The MCAI specifies that the modification must be done on all airplanes in accordance with Bombardier Service Bulletin 601R-28-055, Revision D, dated July 17, 2006, and that accomplishing Bombardier Service Bulletin 601R-28-055, dated May 4, 2004; Bombardier Service Bulletin 601R-28-055, Revision A, dated February 14, 2005; or Bombardier Service Bulletin 601R-28-055, Revision B, dated September 14, 2005; does not satisfy the requirements of the MCAI. This AD requires doing the modification on airplanes on which any Bombardier service bulletin identified in Table 1 of this AD, has not been done. For airplanes on which any Bombardier service bulletin identified in Table 1 of this AD has been done, this AD requires inspecting to determine if the modification is done on both sides of the airplane and modifying the airplane if the modification was not done on both sides.
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.
