Airworthiness Directive · Amendment 39-18099 · Fuel
Airbus Airplanes
This AD applies to the Airbus airplanes specified in paragraphs (c)(1), (c)(2), (c)(3), (c)(4), and (c)(5) of this AD, certificated in any category, all manufacturer serial numbers; except for airplanes modified by supplemental type certificate ST00092BO (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/D41C5AE8E46B4901862574900069E004?OpenDocument&Highlight=st00092bo).
(1) Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes.
(2) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes.
(3) Model A300 B4-605R and B4-622R airplanes.
(4) Model A300 F4-605R and F4-622R airplanes.
(5) Model A300 C4-605R Variant F airplanes.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 series airplanes, Model A300 B4-600, B4-600R, and F4- 600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by a report of chafing found on the overflow sensor harness of the surge tank, and subsequent contact between the electrical wiring and fuel tank structure. This AD requires a one-time inspection for chafing of the overflow sensor harness, and repair if necessary. This AD also requires modification of the sensor harness. We are issuing this AD to prevent chafing of the harness and subsequent contact between the electrical wiring and fuel tank structure, which could result in electrical arcing and a fuel tank explosion and consequent loss of the airplane.
Within 30 months after the effective date of this AD: Perform a one-time general visual inspection for chafing of the outer tank sensor harness between ribs 26 and 27, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-28-0091, dated March 5, 2013 (for Model A300 series airplanes); or Airbus Service Bulletin A300-28-6109, Revision 01, dated December 20, 2013 (for Model A300-600 series airplanes);
(1) If any previous repairs are identified, or if braid and wire insulation is found damaged with the conductor exposed during the inspection required by the introductory text of paragraph (g) of this AD: Before further flight, repair using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA).
(2) If the braid and wire insulation is found damaged without the conductor exposed during the inspection required by the introductory text of paragraph (g) of this AD: Before further flight, repair, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-28-0091, dated March 5, 2013 (for Model A300 series airplanes); or Airbus Service Bulletin A300-28-6109, Revision 01, dated December 20, 2013 (for Model A300-600 series airplanes).
(1) For airplanes on which no damage was found during the inspection required by the introductory text of paragraph (g) of this AD: Before further flight, install modified and error-proof angle brackets to stringer 15 between ribs 26 and 27 of the outer tank sensor harness, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-28-0091, dated March 5, 2013 (for Model A300 series airplanes); or Airbus Service Bulletin A300-28-6109, Revision 01, dated December 20, 2013 (for Model A300-600 series airplanes).
(2) For airplanes on which any damage was found during the inspection required by the introductory text of paragraph (g) of this AD, and the applicable repair required by paragraph (g)(1) or (g)(2) of this AD has been done: Before further flight, install modified and error-proof angle brackets to stringer 15 between ribs 26 and 27 of the outer tank sensor harness, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-28-0091, dated March 5, 2013 (for Model A300 series airplanes); or Airbus Service Bulletin A300-28-6109, Revision 01, dated December 20, 2013 (for Model A300-600 series airplanes).
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.
