Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0228, dated October 12, 2021 (EASA AD 2021-0228) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -215, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. Model A320-215 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2019-03-25, Amendment 39-19577 (84 FR 8805, March 12, 2019) (AD 2019-03-25). AD 2019-03-25 applied to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The NPRM published in the Federal Register on April 11, 2022 (87 FR 21044). The NPRM was prompted by a determination that, for certain airplanes, the compliance time for the initial inspection is inadequate and must be revised and additional actions are required. The NPRM proposed to continue to require the actions specified in AD 2019-03-25 with revised compliance times for certain airplanes and additional actions for certain airplanes, and proposed to expand the applicability, as specified in EASA AD 2021-0228. The FAA is issuing this AD to address the loss of pre-tension in the fasteners, which could affect the structural integrity of the airplane. See the MCAI for additional background information. Discussion of Final Airworthiness Directive Comments The FAA received a comment from United Airlines who supported the NPRM without change. Additional Changes Made to This AD The FAA has added paragraph (i) to this AD to specify that reporting is not required, and redesignated subsequent paragraphs accordingly. The FAA has also removed the Paperwork Reduction Act portion of this AD, as it is no longer relevant. The FAA did not intend to require reporting and these revisions clarify that intent. Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Related Service Information Under 1 CFR Part 51 EASA AD 2021-0228 specifies procedures for repetitive internal and external SDIs (ultrasonic inspections) of the center and outer wing box lower stiffeners and panels at the level of rib 1 junction on the left- and right-hand sides for any cracking, and repair if necessary; and additional actions (re-protection of the inspected area at the lower panel at rib1 junction at the left- and right-hand sides) for airplanes on which certain service information was used. EASA AD 2021-0228 also specifies procedures for an optional modification, which would terminate the repetitive inspections. 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 765 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs for Required Actions Action Labor cost Parts cost Cost per product Cost on U.S. operators Retained actions from 2019-03-25 51 work-hours × $85 per hour = $4,335 $0 $4,335 $25,860 (516 airplanes). New additional actions 13 work-hours × $85 per hour = $1,105 0 1,105 Up to $845,325 (Up to 765 airplanes). The FAA has received no definitive data that enables the agency to provide cost estimates for the repair 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. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive (AD) 2019-03-25, Amendment 39-19577 (84 FR 8805, March 12, 2019); and b. Adding the following new AD: 2022-14-01 Airbus SAS: Amendment 39-22106; Docket No. FAA-2022-0454; Project Identifier MCAI-2021-01124-T.

(c) Applicability This AD applies to Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes; certificated in any category; as identified in European Aviation Safety Agency (EASA) AD 2021-0228, dated October 12, 2021 (EASA AD 2021-0228). (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by a report that taperloks used in the wing-to-fuselage junction at rib 1 were found to be non-compliant with the applicable specification, resulting in a loss of pre-tension in the fasteners; and a determination that, for certain airplanes, the compliance time for the initial inspection is inadequate and must be revised and additional actions are required. The FAA is issuing this AD to address the loss of pre-tension in the fasteners, which could affect the structural integrity of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2021-0228. (h) Exceptions to EASA AD 2021-0228 (1) Where EASA AD 2021-0228 refers to its effective date, this AD requires using the effective date of this AD. (2) Where paragraph (3) of EASA AD 2021-0228 specifies to "contact Airbus for approved repair instructions" if any damage (cracking) is found, for this AD, if any cracking is found, the cracking must be repaired before further flight using a method approved by the Manager, Large Aircraft Section, International Validation Branch, FAA; or EASA; or Airbus SAS's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature. (3) The "Remarks" section of EASA AD 2021-0228 does not apply to this AD. (i) No Reporting Requirement Although the service information referenced in EASA AD 2021-0228 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
