2007-22-03 R1: Fuel tank systems

2007-22-03 R1 Airbus: Amendment 39-16062. Docket No. FAA-2009-0997; Directorate Identifier 2009-NM-158-AD. Effective Date (a) This airworthiness directive (AD) is effective November 12, 2009. Affected ADs (b) This AD revises AD 2007-22-03, Amendment 39-15239. Applicability (c) This AD applies to all Airbus Model A300 B2-1A, B2-1C, B2K- 3C, B2-203, B4-2C, B4-103, and B4-203 airplanes, certificated in any category, except Airbus Model A300-600 airplanes. Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections and critical design configuration control limitations (CDCCLs). Compliance with the operator maintenance documents 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 and CDCCLs, the operator may not be able to accomplish the inspections and CDCCLs 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 (j)(1) of this AD. The request should include a description of changes to the required inspections and CDCCLs that will preserve the critical ignition source prevention feature of the affected fuel system. Unsafe Condition (d) This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane. Compliance (e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Restatement of AD 2007-22-03, With Certain Revised Compliance Methods Revise Airworthiness Limitations Section (ALS) To Incorporate Fuel Maintenance and Inspection Tasks (f) Within 3 months after November 28, 2007 (the effective date of AD 2007-22-03), revise the ALS of the Instructions for Continued Airworthiness to incorporate Airbus A300 Fuel Airworthiness Limitations, Document 95A.1928/05, Issue 2, dated May 11, 2007 (approved by the European Aviation Safety Agency (EASA) on July 6, 2007), Section 1, "Maintenance/Inspection Tasks.'' For all tasks identified in Section 1 of Document 95A.1928/05, the initial compliance times start from the later of the times specified in paragraphs (f)(1) and (f)(2) of this AD, and the repetitive inspections must be accomplished thereafter at the intervals specified in Section 1 of Document 95A.1928/05, except as provided by paragraph (g) of this AD. (1) November 28, 2007. (2) The date of issuance of the original French standard airworthiness certificate or the date of issuance of the original French export certificate of airworthiness.Note 2: Airbus Operator Information Telex SE 999.0079/07, Revision 01, dated August 14, 2007, identifies the applicable sections of the Airbus A300 Airplane Maintenance Manual necessary for accomplishing the tasks specified in Section 1 of Document 95A.1928/05. Initial Compliance Time for Task 28-18-00-03-1 (g) For Task 28-18-00-03-1 identified in Section 1 of Document 95A.1928/05, "Maintenance/Inspection Tasks,'' of Airbus A300 Fuel Airworthiness Limitations, Document 95A.1928/05, Issue 2, dated May 11, 2007 (approved by the EASA on July 6, 2007): The initial compliance time is the later of the times specified in paragraphs (g)(1) and (g)(2) of this AD. Thereafter, Task 28-18-00-03-1 must be accomplished at the repetitive interval specified in Section 1 of Document 95A.1928/05. (1) Prior to the accumulation of 40,000 total flight hours. (2) Within 72 months or 20,000 flight hours after November 28, 2007, whichever occurs first. Revise ALS To Incorporate CDCCLs(h) Within 12 months after November 28, 2007, revise the ALS of the Instructions for Continued Airworthiness to incorporate Airbus A300 Fuel Airworthiness Limitations, Document 95A.1928/05, Issue 2, dated May 11, 2007 (approved by the EASA on July 6, 2007), Section 2, "Critical Design Configuration Control Limitations.'' No Alternative Inspections, Inspection Intervals, or CDCCLs (i) Except as provided by paragraph (j) of this AD: After accomplishing the actions specified in paragraphs (f) and (h) of this AD, no alternative inspections, inspection intervals, or CDCCLs may be used. New Information Explanation of CDCCL Requirements Note 3: 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 paragraphs (f) and (h) of this AD, do not need to be reworked in accordance with the CDCCLs. However, once the ALS has beenrevised, future maintenance actions on these components must be done in accordance with the CDCCLs. Alternative Methods of Compliance (AMOCs) (j)(1) The Manager, International Branch, ANM-116, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Dan Rodina, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, Washington 98057-3356; telephone (425) 227-2125; fax (425) 227-1149. (2) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD.
