Airworthiness Directive · Amendment 39-11772 · Airbus Model A300, A310, and A300-600 Series Airplanes
Airbus Model A300, A310, and A300-600 Series Airplanes
All Model A300, A310, and A300-600 series airplanes, certificated in any category.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (d) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300, A310, and A300-600 series airplanes, that requires an inspection to detect damage of the electrical bonding leads in specified locations of the fuel tanks, and replacement of any damaged electrical bonding leads with serviceable electrical bonding leads. For certain airplanes, this amendment also requires modifying the fuel pipe couplings in specified locations of the fuel tank. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent electrical arcing/discharge in the fuel tank due to damaged electrical bonding leads or inadequate electrical bonding of the fuel pipe couplings, which could result in fuel ignition and consequent uncontained rupture of the fuel tank.
To prevent electrical arcing/discharge in the fuel tank due to damaged electrical bonding leads or inadequate electrical bonding of the fuel pipe couplings, which could result in fuel ignition and consequent uncontained rupture of the fuel tank, accomplish the following:
(a) Within 36 months after the effective date of this AD, perform a one-time inspection to detect damage (i.e., breakage, fraying, abrasion damage, looseness of the outer metal braid protection in the end crimp, looseness of the outer metal braid protection on the bonding lead inner core, corrosion, or missing leads) of the electrical bonding leads in specified locations of the fuel tanks, in accordance with the Accomplishment Instructions of Airbus Service Bulletins A300-28-0072, Revision 01, dated October 01, 1998, including Appendix 1, dated October 01, 1998, and Appendix 2, dated February 20, 1998 (for Model A300 series airplanes); A310-28-2128, Revision 01, dated October 01, 1998, including Appendix 1, dated October 01, 1998, and Appendix 2, dated February 20, 1998 (for Model A310 series airplanes); or A300-28-6057, Revision 01, dated October 01, 1998, including Appendix 1, dated October 01, 1998, and Appendix 2, dated February 20, 1998 (for Model A300-600 series airplanes); as applicable.
Note 2: Inspection of the area specified in paragraph (a) of this AD accomplished prior to the effective date of this AD in accordance with Airbus Service Bulletins A300-28-0072, A310-28-2128, or A300-28-6057; all dated February 20, 1998; as applicable; is considered acceptable for compliance with the requirements of paragraph (a) of this AD.
(b) If any electrical bonding lead is damaged, prior to further flight, replace the bonding lead with a serviceable bonding lead in accordance with the applicable service bulletin specified in paragraph (a) of this AD.
(c) For airplanes on which Airbus Industrie Modification 11847 (for Model A310 series airplanes) or 11848 (for Model A300/A300-600 series airplanes) has not been accomplished, within 36 months after the effective date of this AD, modify the fuel pipe couplings in the specified locations of the fuel tank in accordance with the Accomplishment Instructions of Airbus Service Bulletins A300-28-0073, Revision 01, dated October 01, 1998 (for Model A300 series airplanes); A310-28-2130, Revision 01, dated October 01, 1998 (for Model A310 series airplanes); or A300-28-6058, Revision 01, dated October 01, 1998 (for Model A300-600 series airplanes); as applicable.
Note 3: Modification of the fuel pipe couplings accomplished prior to the effective date of this AD in accordance with Airbus Service Bulletins A300-28-0073, A310-28-2130, or A300-28-6058; all dated February 20, 1998; as applicable; is considered acceptable for compliance with the requirements of paragraph (c) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
