Airworthiness Directive · Amendment 39-18998 · Fuselage
Airbus Airplanes
This AD applies to the Airbus airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) Airbus Model A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes, manufacturer serial numbers identified in Airbus Service Bulletin A330-53-3261, Revision 01, including Appendixes 01, 02, and 03, dated November 10, 2016; and/or Airbus Service Bulletin A330-53-3262, including Appendixes 01 and 02, dated June 23, 2015.
(2) Airbus Model A340-541 and -642 airplanes, manufacturer serial numbers 1030, 1040, 1079, 1091, 1102, and 1122.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-500 and -600 series airplanes. This AD was prompted by a quality control review on the final assembly line, which determined that the wrong aluminum alloy was used to manufacture several structural parts. This AD requires a one-time eddy current conductivity measurement of certain cabin and cargo compartment structural parts to determine if an incorrect aluminum alloy was used, and replacement of any affected part with a serviceable part. We are issuing this AD to address the unsafe condition on these products.
Except as provided by paragraph (i) of this AD: Within 6 years after the effective date of this AD, but not exceeding 12 years since the date of issuance of the original certificate of airworthiness or the date of issuance of the original export certificate of airworthiness; do a one-time eddy current conductivity measurement of the cabin and cargo compartment structural parts identified in the “Affected Part Number” column of table 1 to paragraphs (g) and (h) of this AD to determine if an incorrect aluminum alloy was used, in accordance with the Accomplishment Instructions of the applicable service information identified in paragraph (g)(1), (g)(2), or (g)(3) of this AD.
(1) For cargo compartment structural parts for Model A330 airplanes: Airbus Service Bulletin A330-53-3261, Revision 01, including Appendixes 01, 02, and 03, dated November 10, 2016.
(2) For cabin structural parts for Model A330 airplanes: Airbus Service Bulletin
A330-53-3262, including Appendixes 01 and 02, dated June 23, 2015; except part number F5377004320300, which is located in the “cabin” area, but must be inspected in accordance with Airbus Service Bulletin A330-53-3261, Revision 01, including Appendixes 01, 02, and 03, dated November 10, 2016.
(3) For cargo compartment structural parts for Model A340 airplanes: Airbus Service Bulletin A340-53-5072, including Appendixes 01 and 02, dated June 23, 2015.

If during the inspection required by paragraph (g) of this AD, any affected part having a part number specified in table 1 to paragraphs (g) and (h) of this AD is found to have a measured value greater than that specified in Figure A-GFAAA, Sheet 02, “Inspection Flowchart,” of the applicable service information identified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD, except as provided by paragraph (i) of this AD: Within 6 years after the effective date of this AD, but not exceeding 12 years since the date of issuance of the original certificate of airworthiness or the date of issuance of the original export certificate of airworthiness, replace the affected part with an acceptable replacement part having a part number specified in table 1 to paragraphs (g) and (h) of this AD, in accordance with the Accomplishment Instructions of the applicable service information identified in paragraph (g)(1), (g)(2), or (g)(3) of this AD.
Where Figure A-GFAAA, Sheet 02, “Inspection Flowchart,” of the service information identified in paragraphs (g)(2) and (g)(3) of this AD specifies to “do the conductivity (σ) measurement with 60kHz (refer to Appendix 01) σ480 = ___MS/m,” the correct conductivity measurement is “σ60 = ___MS/m.”
For Model A330 airplanes on which the inspection and replacement, as applicable, specified in paragraphs (g) and (h) of this AD were done before the effective date of this AD, in accordance with Airbus Service Bulletin A330-53-3261, dated June 23, 2015: Within 6 years after the effective date of this AD, but not exceeding 12 years since the date of issuance of the original certificate of airworthiness or the date of issuance of the original export certificate of airworthiness, do a one-time eddy current conductivity measurement of structural parts having part number (P/N) G5367131300000, P/N G5367173700000, and P/N G5367173800000, located in fuselage section 15, in accordance with the “Additional Work” section of the Accomplishment Instructions of Airbus Service Bulletin A330-53-3261, Revision 01, including Appendixes 01, 02, and 03, dated November 10, 2016.
If during the inspection required by paragraph (j) of this AD, any affected part having a part number specified in paragraph (j) of this AD is found to have a measured value greater than that specified in Figure A-GFAAA, Sheet 02, “Inspection Flowchart,” of Airbus Service Bulletin A330-53-3261, Revision 01, including Appendixes 01, 02, and 03, dated November 10, 2016: Within 6 years after the effective date of this AD, but not exceeding 12 years since the date of issuance of the original certificate of airworthiness or the date of issuance of the original export certificate of airworthiness, replace the affected part with an acceptable replacement part having a part number specified in table 1 to paragraphs (g) and (h) of this AD, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-53-3261, Revision 01, including Appendixes 01, 02, and 03, dated November 10, 2016.
