AD 2022-08-08 requires repetitive special detailed inspections of certain double joggle areas on the fuselage and applicable on-condition actions. This proposed AD continues to require the actions in AD 2022-08-08 and would add airplanes to the applicability, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> The FAA must receive comments on this proposed AD by September 9, 2024. </EFFDATE> <HD SOURCE="HED">ADDRESSES:</HD> You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • <E T="03">Federal eRulemaking Portal:</E> Go to <E T="03">regulations.gov.</E> Follow the instructions for submitting comments. • <E T="03">Fax:</E> 202-493-2251. • <E T="03">Mail:</E> U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590. • <E T="03">Hand Delivery:</E> Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. <E T="03">AD Docket:</E> You may examine the AD docket at <E T="03">regulations.gov</E> under Docket No. FAA-2024-1895; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this proposal because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to <E T="03">regulations.gov,</E> including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this NPRM. <HD SOURCE="HD1">Confidential Business Information</HD> CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as “PROPIN.” The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM.

AD 2022-08-08 was prompted by an MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2021-0227, dated October 11, 2021 (EASA AD 2021-0227) (which corresponds to FAA AD 2022-08-08), to correct an unsafe condition. AD 2022-08-08 requires repetitive special detailed inspections of certain areas and applicable on-condition actions. The FAA issued AD 2022-08-08 to address cracks in the double joggle areas at frame (FR) 16 and FR20, right-hand and left-hand sides, which, if not detected and corrected, could reduce the structural integrity of the fuselage. <HD SOURCE="HD1">Actions Since AD 2022-08-08 Was Issued</HD> Since the FAA issued AD 2022-08-08, EASA superseded AD 2021-0227 and issued EASA AD 2023-0212, dated December 6, 2023 (EASA AD 2023-0212) (referred to after this as the MCAI), for certain Airbus SAS Model A318-111, -112, -121, -122 airplanes; Model 319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, and -171N airplanes; Model A320-211, -212, -214, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX airplanes. The MCAI states that the unsafe condition may also exist on Airbus SAS A318/A320/A321 “NEO” airplanes ( <E T="03">i.e.,</E> Airbus SAS Model A318-151N, -153N, and -171N; A320-251N, -252N, -253N, -271N, -272N, and -273N; and A321-251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX airplanes), so these airplanes will be added to the applicability. In addition, Airbus has developed additional, new structural repair manual (SRM) tasks that are considered additional alternative methods to the Airbus repair designs originally required by EASA AD 2021-0227 for the airplanes affected by that AD. The FAA is proposing this AD to address cracks in the double joggle areas at FR16 and FR20 in the nose forward fuselage, which could reduce the structural integrity of the fuselage. You may examine the MCAI in the AD docket at <E T="03">regulations.gov</E> under Docket No. FAA-2024-1895. <HD SOURCE="HD1">Explanation of Retained Requirements</HD> Although this proposed AD does not explicitly restate the requirements of AD 2022-08-08, this proposed AD would retain all of the requirements of AD 2022-08-08 and expands the applicability to include Airbus SAS A318/A320/A321 NEO airplanes. Those requirements are referenced in EASA AD 2023-0212, which, in turn, is referenced in paragraph (g) of this proposed AD. <HD SOURCE="HD1">Related Material Under 1 CFR Part 51</HD> The FAA reviewed EASA AD 2023-0212. This material specifies procedures for repetitive special detailed inspections for cracking of double joggle areas at FR16 and FR20, right-hand and left-hand sides, applicable on-condition actions (repair) and an optional modification of the double joggle area, which terminates the repetitive inspections. The modification includes a rotating probe inspection of certain fastener holes for cracks, a check of the fastener holes for a minimum diameter, and applicable on-condition actions. EASA AD 2023-0212 also specifies that new SRM tasks have been developed that are acceptable for compliance with the corrective actions required by AD 2022-08-08 for airplanes affected by that AD. 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 <E T="02">ADDRESSES</E> . <HD SOURCE="HD1">FAA's Determination</HD> 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.
