Airworthiness Directive · Amendment 39-14921 · Airbus Model A300 Airplanes; A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and A310 Airplanes
Airbus Model A300 Airplanes; A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and A310 Airplanes
This AD applies to all Airbus Model A300 airplanes; A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, A300 F4-605R, F4-622R, and C4-605R Variant F airplanes; and A310 airplanes; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus airplanes identified above. This AD requires improving the routing of certain electrical wire bundles in certain airplane zones, as applicable to the airplane model. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For all airplanes identified in paragraphs (f)(1) and (f)(2) of this AD: Within 26 months after the effective date of this AD, modify the retaining and protection system for the electrical bundles located at the wing-to-fuselage junction, under the flap control screw jack.
(1) For Model A300 airplanes: Do the actions specified in paragraph (f) of this AD in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-24-0085, Revision 06, dated October 13, 2005.
(2) For Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, A300 F4-605R, F4-622R, and C4-605R Variant F airplanes, except those on which Airbus Modification 10505 has been done: Do the actions specified in paragraph (f) of this AD in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-24-6043, Revision 07, dated October 11, 2006.
For Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, A300 F4-605R, F4-622R, and C4-605R Variant F airplanes; except those on which Airbus Modification 11741 has been done: Within 26 months after the effective date of this AD, modify the electrical wiring of routes 1P and 2P (along the top panel of the shroud box and the rear spars of the wings) by extending the protective conduits up to the next support, and replace the two existing clamps on this support with new, improved clamps. Do all actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-28-6056, Revision 01, dated January 20, 2006.
For all airplanes identified in paragraphs (h)(1) and (h)(2) of this AD: Within 26 months after the effective date of this AD, do a general visual inspection of the wire looms on the wing trailing edge for improperly held wires in the clamps, restore the electrical bundles to good condition, and replace the affected nylon clamps with metallic clamps that have an elastomer lining. Do all applicable corrective action before further flight. Repeat the inspection thereafter at intervals not to exceed 26 months until all clamps have been replaced.
(1) For Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, A300 F4-605R, F4-622R, and C4-605R Variant F airplanes; except those on which Airbus Modification 6478 has been done: Do the actions specified in paragraph (h) of this AD in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-24-6004, Revision 04, dated November 15, 2005.
(2) For Model A310 airplanes, except those on which Airbus Modification 6478 has been done: Do the actions specified in paragraph (h) of this AD in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310-24-2009, Revision 04, dated November 15, 2005.
(i) For all airplanes identified in paragraphs (i)(1), (i)(2), and (i)(3) of this AD: Within 26 months after the effective date of this AD, replace the nylon clamps of the electrical routes in the hydraulic compartment and in the shroud box with new metallic clamps that have white silicone lining (for airplanes identified in paragraph (i)(1) of this AD); and/or replace the nylon clamps and change the location of routes 1P and 2P to improve the retention of the wiring loom (for airplanes identified in paragraphs (i)(2) and (i)(3) of this AD); as applicable.
(1) For Model A300 airplanes; except those on which Airbus Modification 11763 has been done: Do the actions specified in paragraph (i) of this AD in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-24-0100, dated April 7, 2005.
(2) For Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, A300 F4-605R, F4-622R, and C4-605R Variant F airplanes; except those on which Airbus Modifications 11763 and 12995 have been done: Do the actions specified in paragraph (i) of this AD in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-24-6084, Revision 01, dated June 28, 2005.

After the effective date of this AD, no person may install on any airplane plate assemblies with part numbers A5351088000000 or A5351088000100 unless they have been modified in accordance with paragraph (f) of this AD.
Actions done before the effective date of this AD in accordance with the service bulletins identified in Table 1 of this AD are acceptable for compliance with the corresponding requirements in this AD.
