Airworthiness Directive · Amendment 39-18083 · Flight controls
Airbus Airplanes
This AD applies to Airbus Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; 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, and Model A300 C4-605R Variant F airplanes; certificated in any category; all manufacturer serial numbers.
We are superseding Airworthiness Directive (AD) 2009-06-06 for all Airbus Model A310 and A300-600 series airplanes. AD 2009-06-06 required revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations and maintenance tasks for aging systems maintenance. This new AD requires revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. This AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. We are issuing this AD to prevent reduced structural integrity and reduced control of these airplanes due to the failure of system components.
This paragraph restates the requirements of paragraph (n) of AD 2009-06-06, Amendment 39-15842 (74 FR 12228, March 24, 2009). Within 3 months after April 28, 2009 (the effective date of AD 2009-06-06), revise the ALS of the Instructions for Continued Airworthiness (ICA) to incorporate Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006 (for Model A310 series airplanes); or Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006 (for Model A300-600 series airplanes). For all tasks identified in Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; and Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; do the tasks at the later of the times specified in paragraphs (g)(1) and (g)(2) of this AD, as applicable, except as provided by paragraph (h) of this AD. The repetitive inspections must be accomplished thereafter at the interval specified in Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; or Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; as applicable.
(1) At the initial compliance times (thresholds) specified in Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; or Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; as applicable; with the compliance times starting from the later of the times specified in paragraphs (g)(1)(i) and (g)(1)(ii) of this AD.
(i) Since first flight of the airplane.
(ii) Since the applicable part was new or refurbished if the part's life (in flight hours, flight cycles, landings, or calendar time, as applicable) can be conclusively determined.
(2) Within 3 months after doing the revision of the ALS of the ICA required by paragraph (h) of this AD.
Note 1 to paragraph (g) of this AD: For additional guidance on the trimmable horizontal stabilizer actuators (THSA) life limits, refer to Airbus Operators Information Telex (OIT) SE 999.0074/05/BB, dated August 3, 2005.
Note 2 to paragraph (g) of this AD: For additional guidance on the THSA life limits and calculation method for unknown history of parts, refer to Airbus OIT SE 999.0008/07/LB, dated January 16, 2007; and Airbus Service Information Letter 05-008, Revision 01, dated February 21, 2007.
This paragraph restates the requirements of paragraph (o) of AD 2009-06-06, Amendment 39-15842 (74 FR 12228, March 24, 2009), with revised affected airplane language. For airplanes on which any life limitation/maintenance task has been complied with in accordance with the requirements of paragraph (f), (g), (k), (l), or (m) of AD 2009-06-06: The last accomplishment of each limitation/task must be retained as a starting point for the accomplishment of each corresponding limitation/task interval now introduced Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; and Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 01, dated December 21, 2006; as applicable.
This paragraph restates the requirements of paragraph (p) of AD 2009-06-06, Amendment 39-15842 (74 FR 12228, March 24, 2009). Except as provided by paragraph (l) of this AD: After accomplishing the actions specified in paragraphs (g) and (h) of this AD, no alternative inspection, inspection intervals, or limitations may be used, except as required by paragraph (j) of this AD.
Within 3 months after the effective date of this AD: Revise the maintenance or inspection program, as applicable, to incorporate Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated November 30, 2012 (for Model A310 series airplanes); or Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated April 18, 2012, and Airbus A300-600 Variation 0CVLG120001/C0S, dated August 24, 2012, to Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated April 18, 2012 (for Model A300-600 series airplanes). For all limitation/replacement/inspection tasks identified in Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated November 30, 2012; or Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated April 18, 2012, and Airbus A300-600 Variation 0CVLG120001/C0S, dated August 24, 2012, to Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated April 18, 2012; the initial compliance times for the tasks are at the later of the times specified in paragraphs (j)(1) and (j)(2) of this AD, as applicable. Doing any limitation/replacement/inspection task required by this paragraph terminates the corresponding task required by paragraph (g) of this AD.
(1) At the initial compliance times (thresholds) specified in Airbus A310 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated November 30, 2012; or Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated April 18, 2012, and Airbus A300-600 Variation 0CVLG120001/C0S, dated August 24, 2012, to Airbus A300-600 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated April 18, 2012; as applicable; with the compliance times starting from the later of the times specified in paragraphs (j)(1)(i) and (j)(1)(ii) of this AD.

(2) Within 3 months after the effective date of this AD.
After accomplishment of the revision required by paragraph (j) of this AD, no alternative actions (e.g., inspections) or intervals, may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (l)(1) 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.
