2019-13887. Airworthiness Directives; Airbus SAS Airplanes, Federal Register
Home » 2019 Issues » 84 FR (07/01/2019) » 2019-13887. Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A310 series airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
For service information identified in this NPRM, contact Airbus SAS, Airworthiness Office—EAW, Rond-Point Emile Dewoitine No: 2, 31700 Blagnac Cedex, France; phone: +33 5 61 93 36 96; fax: +33 5 61 93 44 51; email: account.airworth-eas@airbus.com; internet: http://www.airbus.com. You may view this service information at the FAA, Transport Standards Branch, 2200 South 216th St., Des Moines, WA. For information on the availability of this material at the FAA, call 206-231-3195.
You may examine the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-0500; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this NPRM, the regulatory evaluation, any comments received, and other information. The street address for Docket Operations is listed above. Comments will be available in the AD docket shortly after receipt.

The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2019-0500; Product Identifier 2019-NM-078-AD” at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this NPRM. The FAA will consider all comments received by the closing date and may amend this NPRM because of those comments.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0091, dated April 26, 2019 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus SAS Model A310 series airplanes. The MCAI states:
The airworthiness limitations for Airbus A310 aeroplanes, which are approved by EASA, are currently defined and published in the A310 [Airworthiness Limitations Section] ALS document(s). The Damage Tolerant Airworthiness Limitation Items (DT ALI) are published in ALS Part 2.
Previously, EASA issued AD 2017-0206 [which corresponds to FAA AD 2018-19-31, Amendment 39-19432 (83 FR 48930, September 28, 2018) (“AD 2018-19-31”)] to require accomplishment of all DT ALI maintenance tasks as described in the Airbus A310 ALS Part 2 at Revision 02.
For the reason described above, this [EASA] AD retains the requirements of EASA AD 2017-0206, which is superseded, and requires accomplishment of the actions specified in the ALS.
The unsafe condition is fatigue cracking, damage, or corrosion in principal structural elements, which could result in reduced structural integrity of the airplane. You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-0500.
Relationship Between Proposed AD and AD 2018-19-31
This NPRM does not propose to supersede AD 2018-19-31. Rather, we have determined that a stand-alone AD is more appropriate to address the changes in the MCAI. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Accomplishment of the proposed actions would then terminate all of the requirements of AD 2018-19-31.
Airbus has issued Airbus A310 Airworthiness Limitations Section (ALS) Part 2, Damage Tolerant Airworthiness Limitation Items (DT-ALI), Revision 03, dated December 14, 2018 (“Airbus A310 ALS Part 2, DT-ALI, Revision 03”), as supplemented by Airbus A310 ALS Part 2, Damage Tolerant Airworthiness Limitation Items (DT-ALI), Variation 3.1, Issue 01, dated December 20, 2018 (“Airbus A310 ALS Part 2, DT-ALI, Variation 3.1, Issue 01”). Airbus A310 ALS Part 2, DT-ALI, Revision 03, describes mandatory maintenance tasks that operators must perform at specified intervals. Airbus A310 ALS Part 2, DT-ALI, Variation 3.1, Issue 01, describes additional mandatory maintenance tasks related to wide-spread fatigue damage that operators must perform at specified intervals. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
The MCAI specifies that, if there are findings from the airworthiness limitations section (ALS) inspection tasks, corrective actions must be accomplished in accordance with Airbus maintenance documentation. However, this proposed AD does not include that requirement. Operators of U.S.-registered airplanes are required by general airworthiness and operational regulations to perform maintenance using methods that are acceptable to the FAA. The FAA considers those methods to be adequate to address any corrective actions necessitated by the findings of ALS inspections required by this proposed AD.
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more Start Printed Page 31251detail the scope of the Agency's authority.
(2) Will not affect intrastate aviation in Alaska; and
Airbus SAS: Docket No. FAA-2019-0500; Product Identifier 2019-NM-078-AD.
Within 90 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Airbus A310 Airworthiness Limitations Section (ALS), Part 2, Damage Tolerant Airworthiness Limitation Items (DT-ALI), Revision 03, dated December 14, 2018 (“Airbus A310 ALS Part 2, DT-ALI, Revision 03”), as supplemented by Airbus A310 Airworthiness ALS, Part 2, Damage Tolerant Airworthiness Limitation Items (DT-ALI), Variation 3.1, Issue 01, dated December 20, 2018 (“Airbus A310 ALS Part 2, DT-ALI, Variation 3.1, Issue 01”). The initial compliance time for doing the tasks is at the time specified in Airbus A310 ALS Part 2, DT-ALI, Revision 03, as supplemented by Airbus A310 ALS Part 2, DT-ALI, Variation 3.1, Issue 01; or within 90 days after the effective date of this AD; whichever occurs later.
