Airworthiness Directive · Amendment 39-15414 · Fuel
Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
Superseded. A later AD replaced this one: AD 2008-22-03. Comply with the one in force.
This AD applies to all Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, all serial numbers.
Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (g)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
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 60 days after the effective date of this AD, or on or before December 16, 2008, whichever occurs first, revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate the inspection and maintenance requirements, as applicable, in Appendix D, “Fuel System Limitations,” of Part 2, “Airworthiness Requirements,” of Bombardier CL-600-2B19 Maintenance Requirements Manual CSP A-053, Revision 7, dated May 10, 2007 (“the MRM”), task numbers 28-11-00-601, 28-11-00-602, 28-11-00-603, 28-11-00-604, 29-33-01-601, and 29-33-01-602. For those task numbers, the initial compliance times start from the later of the times specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, and the repetitive inspections must be accomplished thereafter at the interval specified in the MRM, except as provided by paragraphs (f)(2), (f)(3), (f)(4), (f)(5) and (g)(1) of this AD. Accomplishing the revision in accordance with a later revision of the MRM is an acceptable method of compliance if the revision is approved by the Manager, New York Aircraft Certification Office (ACO), FAA, or Transport Canada Civil Aviation (TCCA) (or its delegated agent).
(i) The effective date of this AD.
(ii) The date of issuance of the original Canadian standard airworthiness certificate or the date of issuance of the original Canadian export certificate of airworthiness.
(2) For airplanes having more than 15,000 flight hours as of the effective date of this AD, the initial compliance time for Tasks 28-11-00-601, 28-11-00-602, 28-11-00-603, and 28-11-00-604 is within 5,000 flight hours after the effective date of this AD. Thereafter, these tasks must be accomplished within the repetitive interval specified in Appendix D, “Fuel System Limitations,” of Part 2, “Airworthiness Requirements,” of Bombardier CL-600-2B19 Maintenance Requirements Manual CSP A-053, Revision 7, dated May 10, 2007.
(3) For Task 29-33-01-601, the initial compliance time is within 5,000 flight hours after the effective date of this AD. Thereafter, task 29-33-01-601 must be accomplished within the repetitive interval specified in Appendix D, “Fuel System Limitations,” of Part 2, “Airworthiness Requirements,” of Bombardier CL-600-2B19 Maintenance Requirements Manual CSP A-053, Revision 7, dated May 10, 2007.
(4) For airplanes having more than 27,500 flight hours as of the effective date of this AD, the initial compliance time for Task 29-33-01-602 is within 2,500 flight hours after the effective date of this AD. Thereafter, this task must be accomplished within the repetitive interval specified in Appendix D, “Fuel System Limitations,” of Part 2, “Airworthiness Requirements,” of Bombardier CL-600-2B19 Maintenance Requirements Manual CSP A-053, Revision 7, dated May 10, 2007.
(5) After accomplishing the actions specified in paragraphs (f)(1), (f)(2), (f)(3), and (f)(4) of this AD, no alternative inspections or inspection intervals may be used unless the inspection or interval is part of a later revision of Appendix D, “Fuel System Limitations,” of Part 2, “Airworthiness Requirements,” of Bombardier CL-600-2B19 Maintenance Requirements Manual CSP A-053, Revision 7, dated May 10, 2007, that is approved by the Manager, New York ACO, FAA, or TCCA (or its delegated agent); or the limit or interval is approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g)(1) of this AD.
Note 2: 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.
