# SUPPLEMENTARY INFORMATION:

## Background

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2022-19-02, Amendment 39-22171 (87 FR 68891, November 17, 2022) (AD 2022-19-02). AD 2022-19-02 applied to certain Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes; and Model A330-841 and A330-941 airplanes. AD 2022-19-02 required revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations. The FAA issued AD 2022-19-02 to address the failure of system components, which could reduce the controllability of the airplane.

                    The NPRM published in the                     **Federal Register**                     on April 1, 2024 (89 FR 22358). The NPRM was prompted by AD 2024-0014, dated January 10, 2024, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2024-0014) (also referred to as the MCAI). The MCAI states that new or more restrictive airworthiness limitations have been developed.                

In the NPRM, the FAA proposed to continue to require certain actions in AD 2022-19-02, and to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in EASA AD 2024-0014. The FAA is issuing this AD to address the failure of system components. The unsafe condition, if not addressed, could reduce the controllability of the airplane.

                    You may examine the MCAI in the AD docket at                     *regulations.gov*                     under Docket No. FAA-2024-0770.                

## Discussion of Final Airworthiness Directive

## Comments

The FAA received a comment from Delta Air Lines (Delta). The following presents the comments received on the NPRM and the FAA's response to each relevant comment.

## Request To Supersede Two ADs for Certain Airplanes

Delta requested that the FAA supersede FAA AD 2013-16-11, Amendment 39-17549 (78 FR 52405, August 23, 2013) (AD 2013-16-11) and FAA AD 2013-22-02, Amendment 39-17634 (78 FR 65187, October 31, 2013) (AD 2013-22-02) for the Airbus SAS Model A330-300 series airplanes in their applicability, since the actions in the proposed AD would duplicate the requirements of those ADs. Delta noted that the proposed AD would continue to require certain actions in AD 2022-19-02 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, specifically, Airbus A330 ALS Part 4 Revision 9, dated October 2, 2023, (A330 ALS Part 4 Revision 9) as specified in EASA AD 2024-0014. Delta added that the A330 ALS Part 4 Revision 9 includes two new tasks that duplicate the requirements in AD 2013-16-11 and AD 2013-22-02, providing an equivalent level of safety. Delta noted that those FAA ADs did not IBR the corresponding EASA ADs mentioned in the two new tasks. Delta stated that FAA AD 2013-16-11 requires a trimmable horizontal stabilizer actuator (THSA) ball screw shaft integrity test in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-27-3191, dated June 7, 2012, while task 274400-00006-1-E of A330 ALS Part 4 Revision 9 requires that integrity check with the same compliance time and gives credit for the last inspection using that service information. Delta added that FAA AD 2013-22-02 requires repetitive inspections of the gaps between the screw shaft and the tie rod teeth of the THSA in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-27-3179, Revision 01, while task 274400-00005-1-E requires those inspections with the same compliance time and gives credit for the last inspection using that service information.

                    The FAA disagrees with the commenter's request because AD 2013-16-11 and AD 2013-22-02 are applicable not only to Airbus SAS Model A330-300 series airplanes, but also to Model A340-200 and -300 series airplanes fitted with THSAs having specific part numbers. The A330 ALS Part 4 Revision 9 tasks are applicable to THSAs with Part Number (P/N) 47147-710, while FAA AD 2013-16-11 is applicable to any THSAs with P/N 47147-500 or P/N 47147-700, and FAA AD 2013-22-02 requires inspection of any THSA having P/N 47147-500 or P/N 47147-700. Furthermore, compliance times and corrective actions, including the replacement of the affected part, are more detailed in the ADs than in the A330 ALS Part 4 Revision 9. Additionally, EASA did not terminate or supersede EASA ADs 2012-0061R1,                           ( print page 8665)                        dated November 30, 2012 (which corresponds to FAA AD 2013-22-02) and 2012-0210, dated October 11, 2012 (which corresponds to FAA AD 2013-16-11). The FAA has not changed this AD as a result of this comment.                

## Additional Changes Made to This Final Rule

The FAA revised the Costs of Compliance Section of this final rule to include the estimated costs of retained actions, which were inadvertently omitted from the NPRM.

The FAA also added paragraph (m) of this AD to specify terminating action for certain other ADs and added those ADs to paragraph (b) of this AD. The FAA intended to carry over this terminating action from AD 2022-19-02.

The FAA also removed paragraph (m)(3) of the proposed AD, which related to using service information with required for compliance (RC) tagging, since the required service information does not use RC tagging.

## Conclusion

This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator.

## Material Incorporated by Reference Under 1 CFR Part 51

The FAA reviewed EASA AD 2024-0014. This material specifies new or more restrictive airworthiness limitations for airplane structures and safe life limits.

This AD also requires EASA AD 2021-0250, dated November 17, 2021, which the Director of the Federal Register approved for incorporation by reference as of December 22, 2022 (87 FR 68891, November 17, 2022).

                    This material 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

The FAA estimates that this AD affects 140 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

The FAA estimates the total cost per operator for the retained actions from AD 2022-19-02 to be $7,650 (90 work-hours × $85 per work-hour).

The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate.

The FAA estimates the total cost per operator for the new actions to be $7,650 (90 work-hours × $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.

The FAA is 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.

## 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) Will not affect intrastate aviation in Alaska, and

(3) 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.
