# [Amended]
**AGENCY:**
Federal Aviation Administration (FAA), DOT.
**ACTION:**
Notice of proposed rulemaking (NPRM).
**SUMMARY:**
The FAA proposes to supersede Airworthiness Directive (AD) 2025-03-06 and AD 2025-17-07, which apply to certain Airbus SAS Model A318 and A320 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, and -171N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX airplanes. AD 2025-17-07 also applies to Airbus SAS Model A321-253NY airplanes. AD 2025-03-06 and AD 2025-17-07 require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2025-03-06 and AD 2025-17-07, the FAA has determined that additional new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2025-03-06 and all actions in AD 2025-17-07. This proposed AD would also require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations and add new airplane models. The FAA is proposing this AD to address the unsafe condition on these products.

**Background**
The FAA issued AD 2025-03-06, Amendment 39-22954 (90 FR 9595, February 14, 2025) (AD 2025-03-06), for certain Airbus SAS Model A318 and A320 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, and -171N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX airplanes. AD 2025-03-06 was prompted by an MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2024-0031, dated January 31, 2024; corrected February 1, 2024 (EASA AD 2024-0031), to correct an unsafe condition.
AD 2025-03-06 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations (specified in Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 2, Damage Tolerant Airworthiness Limitation Items (DT—ALI), Revision 10, Issue 02, dated November 30, 2023). The FAA issued AD 2025-03-06 to address fatigue cracking, accidental damage, or corrosion in principal structural elements, which could result in reduced structural integrity of the airplane.
The FAA issued AD 2025-17-07, Amendment 39-23117 (90 FR 41771, August 27, 2025) (AD 2025-17-07), for certain Airbus SAS Model A318, A320, and A321 series airplanes; and Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, and -171N airplanes. AD 2025-17-07 was prompted by EASA AD 2024-0208, dated October 25, 2024 (EASA AD 2024-0208), to correct an unsafe condition.
AD 2025-17-07 requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations (specified in Airbus A318/A319/A320/A321 ALS Part 2, Damage Tolerant Airworthiness Limitation Items (DT—ALI), Variation 10.3, dated August 7, 2024). The FAA issued AD 2025-17-07 to address fatigue cracking, accidental damage, or corrosion in principal structural elements, which could result in reduced structural integrity of the airplane.
**Actions Since EASA AD 2024-0031 and AD 2024-0208 Were Issued**
EASA issued AD 2025-0030, dated February 10, 2025 (EASA AD 2025-0030) (also referred to as the MCAI) to supersede AD 2024-0031 and AD 2024-0208 (corresponding to FAA AD 2025-03-06 and AD 2025-17-07, respectively), for certain Airbus SAS Model A318, A319, and A321 series airplanes; and Model A320-211, -212, -214, -215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes. Model A320-215 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this proposed AD therefore does not include those airplanes in the applicability. The MCAI states that new or more restrictive airworthiness limitations have been developed, as specified in Airbus A318/A319/A320/A321 ALS Part 2, Damage Tolerant Airworthiness Limitation Items (DT—ALI), Revision 11, dated November 4, 2024.
The FAA is proposing this AD to address the unsafe condition on these products. The FAA is also proposing to add Model A319-173N and A321-253NY airplanes to the applicability. You may examine the MCAI in the AD docket at *regulations.gov* under Docket No. FAA-2025-3989.
**Material Incorporated by Reference Under 1 CFR Part 51**
The FAA reviewed EASA AD 2025-0030. This material specifies new or more restrictive airworthiness limitations for airplane structures and safe life limits.
This proposed AD would also require EASA AD 2024-0208, which the Director of the Federal Register approved for incorporation by reference as of October 1, 2025 (90 FR 41771, August 27, 2025).
This proposed AD would also require EASA AD 2024-0031, which the Director of the Federal Register approved for incorporation by reference as of March 21, 2025 (90 FR 9595, February 14, 2025).
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.
**FAA's Determination**
These products have been approved by the civil aviation authority of another country and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, that authority has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design.
**Proposed AD Requirements in This NPRM**
This proposed AD would retain certain requirements of AD 2025-03-06 and all requirements of AD 2025-17-07. This proposed AD would also require revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, which are specified in EASA AD 2025-0030 already described, as proposed for incorporation by reference. Any differences with EASA AD 2025-0030 are identified as exceptions in the regulatory text of this proposed AD.
This proposed AD would require revisions to certain operator maintenance documents to include new actions ( *e.g.,* inspections) and Critical Design Configuration Control Limitations (CDCCLs). Compliance with these actions and CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance (AMOC) according to paragraph (p)(1) of this proposed AD.
**Explanation of Required Compliance Information**
In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to retain the IBRs of EASA AD 2024-0031 and EASA AD 2024-0208 and incorporate EASA AD 2025-0030 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024-0031, EASA AD 2024-0208, and EASA AD 2025-0030 through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2024-0031, EASA AD 2024-0208, or EASA AD 2025-0030 does not mean that operators need comply only with that section. For example, where the AD requirement refers to “all required actions and compliance times,” compliance with this proposed AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in EASA AD 2024-0031, EASA AD 2024-0208, or EASA AD 2025-0030. Material required by EASA AD 2024-0031, EASA AD 2024-0208, and EASA AD 2025-0030 for compliance will be available at *regulations.gov* by searching for and locating Docket No. FAA-2025-3989 after the FAA final rule is published.
**Airworthiness Limitation ADs Using the New Process**
The FAA's process of incorporating by reference MCAI ADs as the primary source of information for compliance with corresponding FAA ADs has been limited to certain MCAI ADs (primarily those with service bulletins as the primary source of information for accomplishing the actions required by the FAA AD). However, the FAA is now expanding the process to include MCAI ADs that require a change to airworthiness limitation documents, such as airworthiness limitation sections.
For these ADs that incorporate by reference an MCAI AD that changes airworthiness limitations, the FAA requirements are unchanged. Operators must revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in the new airworthiness limitation document. The airworthiness limitations must be followed according to 14 CFR 91.403(c) and 91.409(e).
The previous format of the airworthiness limitation ADs included a paragraph that specified that no alternative actions ( *e.g.,* inspections), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an AMOC in accordance with the procedures specified in the AMOCs paragraph under “Additional AD Provisions.” This new format includes a “New Provisions for Alternative Actions, Intervals, and CDCCLs” paragraph that does not specifically refer to AMOCs, but operators may still request an AMOC to use an alternative action, interval, or CDCCL.
**Costs of Compliance**
The FAA estimates that this AD, if adopted as proposed, would affect 1,900 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:
The FAA estimates the total cost per operator for the retained actions from AD 2025-03-06 to be $7,650 (90 work-hours × $85 per work-hour).
The FAA estimates the total cost per operator for the retained actions from AD 2025-17-07 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 proposed 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**
The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
(1) Is not a “significant regulatory action” under Executive Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would 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.
