AD 2018-24-04

We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 Freighter, A330-200, and A330-300 series airplanes. This AD was prompted by a revision of a certain airworthiness limitations item (ALI) document, which specifies new or more restrictive maintenance instructions and airworthiness limitations, and a determination that those maintenance instructions and airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance instructions and airworthiness limitations. 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:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A330-200 Freighter, A330-200, and A330-300 series airplanes. The NPRM published in the Federal Register on August 10, 2018 (83 FR 39633). The NPRM was prompted by a revision of a certain ALI document, which specifies new or more restrictive maintenance instructions and airworthiness limitations, and a determination that those maintenance instructions and airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance instructions and airworthiness limitations.
We are issuing this AD to address fatigue cracking, damage, and corrosion in principal structural elements; such fatigue cracking, damage, and corrosion could result in reduced structural integrity ofthe airplane.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0068, dated March 26, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus SAS Model A330-200 Freighter, A330-200, and A330-300 series airplanes. The MCAI states:

The airworthiness limitations for Airbus A330 and A340 aeroplanes, which are approved by EASA, are currently defined and published in the A330 and A340 [Airworthiness Limitations Section] ALS document(s). The Damage Tolerant Airworthiness Limitation Items (DT ALI) are specified in the ALS Part 2. These instructions have been identified as mandatory actions for continued airworthiness.
Failure to comply with these instructions could result in an unsafe condition [i.e., fatigue cracking, damage, and corrosion in principal structural elements] which could result inreduced structural integrity of the airplane.
Previously, EASA issued AD 2016-0152 [which corresponds to FAA AD 2017-19-13, Amendment 39-19043 (82 FR 43837, September 20, 2017) (``AD 2017-19-13'')] for A330 and A340 aeroplanes to require accomplishment of all maintenance tasks as described in ALS Part 2 Revision 01 (A330 aeroplanes) and Revision 02 (A340 aeroplanes).
Since that [EASA] AD was issued, Airbus published Revision 02 of the ALS Part 2 for A330 aeroplanes, including new and/or more restrictive items.
For the reason described above, this [EASA] AD takes over the requirements from EASA AD 2016-0152 for A330 aeroplanes, and requires accomplishment of all maintenance tasks as described in the ALS. EASA AD 2016-0152 has been revised accordingly, removing A330 aeroplanes from the Applicability.

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-2018- 0639.

Comments

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

Request To Clarify or Remove Previously Approved Alternative Method of Compliance (AMOC)

American Airlines requested that we clarify the applicability of the AMOC approved in letter AIR-676-18-111 R1, dated January 29, 2018, or remove the previously approved AMOC from the proposed AD. The commenter stated that, as currently written, paragraph (j)(1)(ii) of the proposed AD is confusing because it states that the AMOC approved in letter AIR-676-18-111 R1, dated January 29, 2018, previously approved for AD 2017-19-13, would still be approved for the corresponding provisions of the final rule. The commenter explained that this AMOC is limited to a specific organization and is not applicable to all operators.
We agree with the commenter's request for the reasons provided by the commenter. AMOC letter AIR-676-18-111 R1, dated January 29, 2018, was issued specifically to Singapore Technologies Aerospace Limited and is not a global AMOC. We have revised paragraph (j)(1)(ii) of this AD to clarify that the AMOC granted in letter AIR-676-18-111 R1, dated January 29, 2018, is approved as an AMOC for Model A330-300 series airplanes modified from a passenger to freighter configuration under the provisions of FAA Supplemental Type Certificate ST04038NY.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule with the change described previously and minor editorial changes. 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 burdenon any operator or increase the scope of this final rule.

Related Service Information Under 1 CFR Part 51

Airbus SAS has issued Airbus A330 Airworthiness Limitations Section (ALS) Part 2--Damage Tolerant Airworthiness Limitation Items (DT-ALI), Revision 02, Issue 2, dated November 22, 2017. This service information describes maintenance instructions and airworthiness limitations applicable to the DT-ALI. 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 105 airplanes of U.S. registry. We estimate the following costs to comply with this AD:
We have determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimatedthat this action takes 1 work- hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per-operator estimate is more accurate than a per- airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours x $85 per work-hour).

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

[[Page 60758]]

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.
