Airworthiness Directive · Amendment 39-18142 · Time limits/maintenance checks
Airbus Airplanes
This AD applies to all Airbus Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; and all 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.
We are superseding Airworthiness Directive (AD) 2007-14-05 for all Airbus Model A310 and 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). AD 2007-14-05 required revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating certain certification maintenance requirements. This new AD requires revising the maintenance or inspection program to incorporate more restrictive 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 safety-significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition of avionics, hydraulic systems, fire detection systems, fuel systems, or other critical systems.
This paragraph restates the requirements of paragraph (f) of AD 2007-14-05, Amendment 39-15127 (72 FR 39307, July 18, 2007), with no changes. Within 3 months after August 22, 2007 (the effective date of AD 2007-14-05), revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating Airbus A300-600 Certification Maintenance Requirements (CMRs) AI/ST5/829/85, Issue 12, dated February 2005 (for Model A300-600 series airplanes); or Airbus A310 CMR AI/ST5/849/85, Issue 12, dated February 2005 (for Model A310 series airplanes); as applicable. Accomplish the actions specified in the applicable CMRs at the intervals specified in the applicable CMRs, except as provided by paragraph (h) of this AD. Where the CMRs specify to contact the Direction Générale de l'Aviation Civile (DGAC), operators are required to contact the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA. The actions must otherwise be accomplished in accordance with the applicable CMRs.
This paragraph restates the requirements of paragraph (g) of AD 2007-14-05, Amendment 39-15127 (72 FR 39307, July 18, 2007), with no changes. For tasks identified in MSI 78.30.00, “Thrust Reverser Actuation and Cowling,” of Section 2, “CMR `Two Star' Tasks,” of Airbus A300-600 CMR AI/ST5/829/85, Issue 12, dated February 2005; and Airbus A310 CMR AI/ST5/849/85, Issue 12, dated February 2005: The initial compliance time is within 2,000 flight cycles or 12 months after August 22, 2007 (the effective date of AD 2007-14-05), whichever occurs later. Thereafter, actions identified in MSI 78.30.00 must be accomplished within the repetitive interval specified in the applicable CMRs. Where the CMRs specify to contact the DGAC, operators are required to contact the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, for such approvals. The actions must be accomplished in accordance with the applicable CMRs.
Within 3 months after the effective date of this AD, revise the maintenance or inspection program, as applicable, to incorporate Airbus A310 Airworthiness Limitations Section (ALS) Part 3, Certification Maintenance Requirements (CMR), dated November 30, 2012; or Airbus A300-600 ALS Part 3, Certification Maintenance Requirements (CMR), dated April 18, 2012. Except as required by paragraph (k) of this AD, the initial compliance time for accomplishing the actions is at the applicable time specified in Airbus A310 ALS Part 3, Certification Maintenance Requirements (CMR), dated November 30, 2012; or Airbus A300-600 ALS Part 3, Certification Maintenance Requirements (CMR), dated April 18, 2012, as applicable; or within 3 months after the effective date of this AD; whichever occurs later. Accomplishing the requirements in this paragraph terminates the requirements in paragraph (g) of this AD.
After accomplishment of the revision required by paragraph (i) 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) of this AD.
For CMR Task 213000-A0001-1-C, “Pressurization Control,” as identified in Sub-part 3-1, CMR Tasks, of the Airbus A300-600 ALS Part 3, Certification Maintenance Requirements (CMR), dated April 18, 2012: The initial compliance time for the task is at the applicable time specified in paragraphs (k)(1), (k)(2), and (k)(3) of this AD.
(1) For airplanes having accumulated less than 40,000 total flight hours since first flight of the airplane as of the effective date of this AD: Before the accumulation of 40,001 total flight hours.
(2) For airplanes having accumulated 40,000 total flight hours or more since first flight of the airplane as of the effective date of this AD, and on which Aging Systems Maintenance (ASM) Task 213115-04-1, “Cabin Pressure Safety Valve;” or Maintenance Review Board Report (MRBR) Tasks 21.30.00/06 and 21.30.00/08, “Pressurization Control,” have been accomplished: Before the accumulation of 14,000 flight hours after the most recent accomplishment of ASM Tasks 213115-04-1, or MRBR Tasks 21.30.00/06 and 21.30.00/08, whichever occurs later.
(3) For airplanes having accumulated 40,000 total flight hours or more since first flight of the airplane as of the effective date of this AD, and on which ASM Task 213115-04-1, or MRBR Tasks 21.30.00/06 and 21.30.00/08, have not been accomplished: Within 3 months after the effective date of this AD.
