Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0 1. The authority citation for part 39 continues to read as follows:
[[Page 73905]]
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0 2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD) 2005-23-01, Amendment 39-14359 (70 FR 69073, November 14, 2005), and adding the following new AD:
2012-25-02 Bombardier, Inc.: Amendment 39-17283. Docket No. FAA- 2012-0496; Directorate Identifier 2011-NM-263-AD.
(a) Effective Date
This airworthiness directive (AD) becomes effective January 16, 2013.
(b) Affected ADs
This AD supersedes AD 2005-23-01, Amendment 39-14359 (70 FR 69073, November 14, 2005).
(c) Applicability
(1) This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, serial numbers 7003 and subsequent.
(2) 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 (l)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued damage tolerance of the affected structure. The FAA has provided guidance for this determination in FAA Advisory Circular (AC) 25.1529-1A, dated November 20, 2007 (http:// rgl.faa.gov/Regulatory--and--Guidance--Library/ rgAdvisoryCircular.nsf/list/AC%2025.1529-1A/$FILE/AC%2025.1529- 1A.pdf).
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Reason
This AD was prompted by multiple reports of cracks on the forward face of the rear pressure bulkhead (RPB) web. We are issuing this AD to detect and correct cracking in the RPB, which could result in reduced structural integrity and rapid decompression of the airplane.
(f) Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
(g) Retained Revision to the Airworthiness Limitations (AWL) Section
This paragraph restates the requirements of paragraph (f) of AD 2005-23-01, Amendment 39-14359 (70 FR 69073, November 14, 2005). For airplanes having serial numbers 7003 through 8025 inclusive, 8030, and 8034: Within 30 days after November 29, 2005 (the effective date of AD 2005-23-01), revise the AWL section of the Instructions for Continued Airworthiness of the Canadair Regional Jet Maintenance Requirements Manual (MRM), Part 2, Appendix B, ``Airworthiness Limitations,'' by incorporating the information specified in AWL 53- 61-153 of the Canadair Regional Jet Temporary Revision (TR) 2B-2109, dated October 13, 2005, into the AWL section. Perform the applicable detailed and special detailed inspections for cracking of the aft pressure bulkhead, as specified in that TR, at the applicable compliance time specified in table 1 to paragraph (g) of this AD. Repeat the detailed inspection thereafter at intervals not to exceed 1,085 flight cycles, and repeat the special detailed inspection thereafter at intervals not to exceed 4,360 flight cycles, in accordance with the procedures specified in AWL 53-61-153, as introduced by Canadair Regional Jet TR 2B-2109, dated October 13, 2005, to Appendix B, ``Airworthiness Limitations, of Part 2 of the Canadair Regional Jet MRM. Accomplishing the revision required by paragraph (i) of this AD terminates the requirements of this paragraph.
