AD 2018-17-16

We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes; 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); and Model A310 series airplanes. This AD was prompted by a static analysis performed by Airbus SAS that revealed some areas of the wing structure cannot sustain the damage limits previously published in certain structural repair manuals. This AD requires an inspection to determine whether repair or damage to certain wing areas is beyond the allowable limits; and repair if necessary. We are issuing this AD to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus SAS Model A300 series airplanes; 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); and Model A310 series airplanes. The NPRM published in the Federal Register on June 12, 2017 (82 FR 26869).

[[Page 43745]]

We are issuing this AD to address any repair or damage on the wing structure that is outside the allowable structural limits. Such conditions could reduce the structural integrity of the wings and could result in loss of control of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016-0229, dated November 15, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``theMCAI''), to correct an unsafe condition for all Airbus SAS Model A300 series airplanes; 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); and Model A310 series airplanes. The MCAI states:

A static analysis performed by Airbus on A300, A310, A300-600, and A300-600ST aeroplanes, revealed that some areas of the wing structure cannot sustain the damage previously published in the A300, A310, A300-600, and A300-600ST Structural Repair Manuals (SRM).
The SRMs were therefore amended to reduce the dimensions of allowable damage and to indicate the areas of the wing structure where damage is no longer acceptable.
This condition, if not detected, could reduce the structural integrity of the wings.
Consequently, Airbus issued Service Bulletins (SB) A300-57-0256, A310-57-2102, A300-57-6114, and A300-57-9027 (hereafter referred to as ``the applicable Airbus SB''), as applicablefor A300, A310, A300-600, and A300-600ST aeroplanes, to inspect the areas identified in these SBs and determine if the repair(s) or damage(s) found stay within the limits indicated in the latest SRM issue (including temporary revisions).
For the reason described above, this [EASA] AD requires accomplishment of an inspection of the aeroplane records. If aeroplane records are missing or incomplete, a Detail Inspection (DET) of specific wing areas is required to ensure that no repair or damage is beyond the limits allowed in the current revision of the SRM (including temporary revisions) [and repair if necessary].

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-2017- 0554.

Comments

We gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA's response to each comment. FedEx stated that it supported the NPRM.

Request To Delay the Issuance Pending New Service Information

Airbus and United Parcel Service (UPS) requested that we delay issuance of the final rule until new service information is released. Airbus stated that a configuration issue and an allowable damage limit issue has been identified for certain freighter manufacturer serial numbers, as specified in Airbus Service Bulletin A300-57-6114, Revision 00, dated August 3, 2015. Airbus also stated that it intends to update the service information.
UPS stated that certain configurations specified in Airbus Service Bulletin A300-57-6114, Revision 00, dated August 3, 2015, do not meet the intent of the proposed AD because airplanes with a freighter configuration have an additional inspection of the wing lower skin between ribs 26 and 27. UPS also stated that the allowable damage limitations are inconsistent between Airbus Service Bulletin A300-57- 6114, Revision 00, dated August 3, 2015, and applicable SRM references.
We agree with the commenters' request. Since the NPRM has been issued, Airbus SAS has issued Service Bulletin A300-57-6114, Revision 01, dated June 19, 2018, and has updated the applicable SRMs referenced in the service information. Airbus Service Bulletin A300-57-6114, Revision 01, dated June 19, 2018, does not contain substantive changes. Therefore, we have revised paragraph (i)(2) of this AD to refer to Airbus Service Bulletin A300-57-6114, Revision 01, dated June 19, 2018. We have also added paragraph (j) of this AD to give credit for actions in paragraph (g) of this AD completed before the effective date of this AD using Airbus Service Bulletin A300-57-6114, Revision 00, dated August 3, 2015. We redesignated subsequent paragraphs accordingly.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorialchanges. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.
We also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule.

Related Service Information Under 1 CFR Part 51

We reviewed the following Airbus SAS Service Information.
Airbus Service Bulletin A300-57-0256, Revision 00, dated August 3, 2015 (Airbus Model A300 series airplanes).
Airbus Service Bulletin A300-57-6114, Revision 01, dated June 19, 2018 (for 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)).
Airbus Service Bulletin A310-57-2102, Revision 00, dated August 3, 2015 (for Model A310 series airplanes).
This service information describes a review of the airplane maintenance records and a detailed inspection of the left-hand and right-hand wing areas to determine whether any repair or damage is beyond the allowable limits in the current revision of the SRM, and repair if necessary. These documents are distinct since they apply to different airplane models in different configurations. 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.

Costs of Compliance

We estimate that this AD affects 128 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection..................... Up to 18 work-hours x $0 Up to $1,530...... Up to $195,840.
$85 per hour = $1,530. ----------------------------------------------------------------------------------------------------------------

[[Page 43746]]

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD.

Authority for This Rulemaking

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 detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.

Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
