This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes; Model A300 B4-605R and B4-622R airplanes; Model A300 F4-605R and F4-622R airplanes; Model A300 C4-605R Variant F airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; certificated in any category; all serial numbers.
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:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 30 days after the effective date of this AD, do a general visual inspection for missing pipes, or distortions or holes, of the fuel drain pipes of the LAPF, and if no missing pipes, distortions, and holes are found, do a general visual inspection to determine the length and part number of the drain pipe attachment screws on the LAPF on the left-hand and right-hand pylons, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-54A6039, Revision 01, dated March 11, 2010 (for Model A300-600 series airplanes); or A310-54A2040, Revision 02, dated June 10, 2010 (for Model A310 series airplanes).
(1) If missing pipes, distortions, or holes of the fuel drain pipes are detected during any inspection required by paragraph (g) of this AD, before further flight, replace the drain pipe, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-54A6039, Revision 01, dated March 11, 2010 (for Model A300-600 series airplanes); or A310-54A2040, Revision 02, dated June 10, 2010 (for Model A310 series airplanes); or contact Airbus for repair instructions and do the repair; except where the applicable service bulletin specifies using washers having part number (P/N) NSA5149-4, washers having P/N NSA5149-3 may alternatively be used.
(2) If screw length is outside the measurement specified in the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-54A6039, Revision 01, dated March 11, 2010 (for Model A300-600 series airplanes); or A310-54A2040, Revision 02, dated June 10, 2010 (for Model A310 series airplanes); or screws having incorrect part numbers are found during any inspection required by paragraph (g) of this AD, before further flight, replace the screws with screws having P/N NAS1102E3-10, NAS1102E3-12, or NAS560HK3-2, as applicable to location and airplane (engine) configuration, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-54A6039, Revision 01, dated March 11, 2010 (for Model A300-600 series airplanes); or A310-54A2040, Revision 02, dated June 10, 2010 (for Model A310 series airplanes); except where the applicable service bulletin specifies using washers having P/N NSA5149-4, washers having P/N NSA5149-3 may alternatively be used.
(h) As of the effective date of this AD, do not install screws on the LAPF, other than screws having P/N NAS1102E3-10, NAS1102E3-12, or NAS560HK3-2, as applicable to location and airplane (engine) configuration, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-54A6039, Revision 01, dated March 11, 2010 (for Model A300-600 series airplanes); or A310-54A2040, Revision 02, dated June 10, 2010 (for Model A310 series airplanes).

| For model— | Airbus Mandatory Service Bulletin— | Revision— | Dated— |
|---|---|---|---|
| A300-600 series airplanes | A300-54A6039 | Original | January 19, 2010. |
| A310 series airplanes | A310-54A2040 | Original | January 19, 2010. |

Although Airbus Mandatory Service Bulletins A300-54A6039, Revision 01, dated March 11, 2010; and A310-54A2040, Revision 02, dated June 10, 2010; specify to submit certain information to the manufacturer, this AD does not include that requirement.
Note 1: This AD differs from the MCAI and/or service information as follows: Although the MCAI or service information tells you to submit information to the manufacturer, paragraph (j) of this AD does not require that information.
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.
