Airworthiness Directive · Amendment 39-15391 · Fuel
ATR Model ATR42 and ATR72 Airplanes
Superseded. A later AD replaced this one: AD 2008-04-19 R1. Comply with the one in force.
This AD applies 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; certificated in any category.
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) 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 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. For all tasks identified in the applicable MRBR, the initial compliance times start from the later of the times specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, except as provided by paragraphs (f)(3) and (g) of this AD. The repetitive inspections must be accomplished thereafter at the interval specified in the applicable MRBR.
(i) The effective date of this AD.
(ii) The date of issuance of the original French standard airworthiness certificate or the date of issuance of the original French export certificate of airworthiness.
(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.
(3) For the task titled “Detailed visual inspection of the fuel tanks and associated equipment, wiring, piping and braids” (CMR task reference 28.10.00-1): The initial compliance time is the later of the times specified in paragraphs (f)(3)(i) and (f)(3)(ii) of this AD. 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.
(i) Within 144 months since the date of issuance of the original French standard airworthiness certificate or the date of issuance of the original French export certificate of airworthiness.
(ii) Within 72 months or 20,000 flight hours after the effective date of this AD, whichever occurs first.
(4) After accomplishing the actions specified in paragraphs (f)(1), (f)(2), and (f)(3) of this AD, no alternative inspection, inspection intervals, or CDCCLs may be used unless the inspections, intervals, or CDCCLs are part of a later revision of the ATR 42-200/-300/-320 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; that is approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (EASA) (or its delegated agent); or unless the inspections, intervals, or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g) of this AD.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
