You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M-30, West Start Printed Page 10653Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on September 28, 2007 (72 FR 55113). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:
Subsequent to accidents involving Fuel Tank System explosions in flight * * * and on ground, the FAA published Special Federal Aviation Regulation 88 (SFAR 88) in June 2001. SFAR 88 required a safety review of the aircraft Fuel Tank System to determine that the design meets the requirements of FAR (Federal Aviation Regulations) § 25.901 and § 25.981(a) and (b).
Fuel Airworthiness Limitations are items arising from a systems safety analysis that have been shown to have failure mode(s) associated with an ‘unsafe condition’ as defined in FAA's memo 2003-112-15 ‘SFAR 88—Mandatory Action Decision Criteria'. These are identified in Failure Conditions for which an unacceptable probability of ignition risk could exist if specific tasks and/or practices are not performed in accordance with the manufacturers' requirements.
For standardization purposes, we have revised paragraph (f)(4) of this AD to specify that no alternative inspections, inspection intervals, or CDCCLs may be used unless they are part of a later approved revision of ATR 42-200/-300/-320 Maintenance Review Board Report (MRBR), Revision 7, dated March 31, 2006; ATR 42-400/-500 MRBR, Revision 6, dated March 26, 2007; or ATR 72 MRBR, Revision 8, dated March 26, 2007; as applicable; or unless they are approved as an alternative method of compliance. Inclusion of this paragraph in the AD is intended to ensure that the AD-mandated airworthiness limitations changes are treated the same as the airworthiness limitations issued with the original type certificate.
You may examine the AD docket on the Internet at http://www.regulations.gov;​ or in person at the Start Printed Page 10654Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

(1) Within 3 months after the effective date of this AD, or before December 16, 2008, whichever occurs first, revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate Task 28.10.00 “Fuel Tank—General,” and Task 28.20.00 “Distribution,” of the Certification Maintenance Requirements (CMR) Section of the Time Limits Section of Part 1 of the ATR 42-200/-300/-320 Maintenance Review Board Report (MRBR), Revision 7, dated March 31, 2006; the ATR 42-400/-500 MRBR, Revision 6, dated March 26, 2007; or the ATR 72 MRBR, Revision 8, dated March 26, 2007; as applicable.

The repetitive inspections must be accomplished thereafter at the interval specified in the applicable MRBR.
(2) Within 3 months after the effective date of this AD, or before December 16, 2008, whichever occurs first, revise the ALS of the Instructions for Continued Airworthiness to incorporate the CDCCLs as defined in Section 4., “Critical Design Configuration Control List,” of the Airworthiness Limitations Section of the Time Limits Section of Part 1 of the ATR 42-200/-300/-320 MRBR, Revision 7, dated March 31, 2006; the ATR 42-400/-500 MRBR, Revision 6, dated March 26, 2007; or the ATR 72 MRBR, Revision 8, dated March 26, 2007; as applicable.

The missing page number for the “List of Effective Pages” of the Time Limits Section of Part 1 of the ATR 42-200/-300/-320 Maintenance Review Board Report is 1-LEP. The “List of Effective Pages” for the Time Limits Section of Part 1 of the ATR 42-400/-500 Maintenance Review Board Report contains a typographical error: The date for Page 3 should read March 2007. The first page of the “Reasons for Revisions” section of the Time Limits Section of Part 1 of the ATR 72 Maintenance Review Board Report is incorrectly identified as Page 2-RFR; that page should be identified as Page 1-RFR.
