Docket No. FAA-2009-0999
Directorate Identifier 2009-NM-155-AD
Amendment 39-16069
AD 2008-04-19 R1

Restatement of AD 2008-04-19 With Changes to Compliance Method

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' * * *. These are identified in Failure Conditions for which an unacceptable probability of ignition risk could exist if specific tasks and/or Start Printed Page 56714practices are not performed in accordance with the manufacturers' requirements.
On April 3, 2008 (73 FR 10652, February 28, 2008), the Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD.
We must receive comments on this AD by December 18, 2009.

On February 15, 2008, we issued AD 2008-04-19, Amendment 39-15391 (73 FR 10652, February 28, 2008). That AD applied to all ATR Model ATR42-200, -300, -320, and -500 airplanes; and all ATR Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes. That AD required revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate new limitations for fuel tank systems.
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. We are issuing this AD to revise AD 2008-04-19. This new AD retains the requirements of the existing AD, and adds a new note to clarify the intended effect of the AD on spare and on-airplane fuel tank system components. We have renumbered subsequent notes accordingly.
AD 2008-04-19 allowed the use of alternative inspections, inspection intervals, and CDCCLs if they are part of a later revision of the 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. That provision has been removed from this AD. Allowing the use of “a later revision” of a specific service document violates Office of the Federal Register policies for approving materials that are incorporated by reference. Affected operators, however, may request approval to use an alternative inspection, inspection interval, or CDCCL that is part of a later revision of the referenced service documents as an alternative method of compliance, under the provisions of paragraph (g) of this AD.
This revision merely clarifies the intended effect on spare and on-airplane fuel tank system components, and Start Printed Page 56715makes no substantive change to the AD's requirements. For this reason, it is found that notice and opportunity for prior public comment for this action are unnecessary, and good cause exists for making this amendment effective in less than 30 days.
This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2009-0999; Directorate Identifier 2009-NM-155-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

The corrective action is revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate new limitations for fuel tank systems.Start Printed Page 56716
(1) Within 3 months after April 3, 2008 (the effective date of AD 2008-04-19), revise the ALS of the ICA 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.

Thereafter, the task titled “Detailed visual inspection of the fuel tanks and associated equipment, wiring, piping and braids” must be accomplished at the repetitive interval specified 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.

Notwithstanding any other maintenance or operational requirements, components that have been identified as airworthy or installed on the affected airplanes before the revision of the ALS, as required by paragraph (f) of this AD, do not need to be reworked in accordance with the CDCCLs. However, once the ALS has been revised, future maintenance actions on these components must be done in accordance with the CDCCLs.
