AD 2008-22-03 Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

This AD applies to all Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 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 (h)(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.

Unless already done, do the following actions. (1) At the times specified in paragraphs (g)(1)(i), (g)(1)(ii), and (g)(1)(iii) of this AD, as applicable, do the initial inspection for Tasks 28-11-00-601, 28-11-00-602, 28-11-00-603, 28-11-00-604, and 29-33-01-602, as applicable, in Appendix D, “Fuel System Limitations,” of Part 2, “Airworthiness Requirements,” of Bombardier CL-600-2B19 Maintenance Requirements Manual CSP-053, Revision 7, dated May 10, 2007 (“the MRM”), and thereafter repeat the inspection at the applicable interval specified in the MRM, except as provided by paragraphs (g)(2) and (h)(1) of this AD. (i) For airplanes not identified in paragraph (f)(2)(i) of this AD, the initial compliance time for Task 28-11-00-603 is before the accumulation of 20,000 total flight hours, or within 5,000 flight hours after the effective date of this AD, whichever occurs later. (ii) For airplanes not identified in paragraph (f)(4) of this AD, the initial compliance time for Task 29-33-01-602 is before the accumulation of 30,000 total flight hours, or within 2,500 flight hours after the effective date of this AD, whichever occurs later. (iii) For airplanes not identified in paragraph (f)(2)(ii) of this AD, the initial compliance time for Tasks 28-11-00-601, 28-11-00-602, and 28-11-00-604, is within 20,000 flight hours after accomplishing the applicable modsum or service bulletin specified in the MRM for the task, or within 5,000 flight hours after the effective date of this AD, whichever occurs later. (2) After accomplishing the actions specified in paragraphs (g)(1) of this AD, no alternative inspections/limitation tasks or inspection/limitation task intervals may be used unless the inspection/limitation task or inspection/limitation task interval is approved as an AMOC in accordance with the procedures specified in paragraph (h)(1) of this AD. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (h) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, New York Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
