Airworthiness Directive · Amendment 39-15199 · Stabilizers
Airbus Model A300-600R Series Airplanes; and Model A310-300 Series Airplanes
This AD applies to Airbus Model A310-300 and A300-600R series airplanes; certificated in any category; all serial numbers fitted with a THS (trimmable horizontal stabilizer) containing fuel on which, during production Airbus Modifications 04801 and 04802 have been embodied, and Airbus Modification 06549 has not been embodied; except aircraft on which Airbus Modification 13191 has been embodied in production, or Airbus Service Bulletin A310-55-2042 or A300-55-6041 has been incorporated in service.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, within 60 months after the effective date of this AD, do the actions specified in paragraphs (f)(1) through (f)(6) of this AD in accordance with the instructions given in Airbus Service Bulletin A300-55-6041 or A310-55-2042, both dated September 13, 2006, as applicable.
(1) Remove the 8 THS metallic hoisting lugs.
(2) Do a detailed visual inspection of the internal base of the 8 THS hoist point fittings in order to detect visible signs of score, cracks, perforation or other damage.
(3) In case of no finding, before further flight install the new plastic plugs.
(4) In case of any finding, before further flight, entry into the fuel trim tank is required to do a detailed visual inspection for structural damage of the hoist point fittings base inside the fuel tank.
(5) If structural damage is not confirmed, before further flight blend-out/protect the scoring area of the fitting internal base and install the new plastic plugs.
(6) If structural damage is confirmed, before further flight repair the damaged fittings and install the new plastic plugs.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
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.
