Airworthiness Directives; Airbus SAS Airplanes
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule.
SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes. This AD was prompted by a widespread fatigue damage (WFD) scenario review for a certification project that indicated several cracks found around the potable water and wastewater service panels were WFD instead of typical fatigue. This AD requires modification of the potable water and wastewater service panels, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
DATES:
This AD is effective June 5, 2025.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 5, 2025.
ADDRESSES:
AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2025-0009; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION:
Background
[top] The FAA 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 A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes. The NPRM published in the Federal Register on January 23, 2025 (90 FR 7996). The NPRM was prompted by AD 2024-0105, dated May 30, 2024, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2024-0105) (also referred to as the MCAI). The MCAI
In the NPRM, the FAA proposed to require modification of the potable water and wastewater service panels, as specified in EASA AD 2024-0105. The FAA is issuing this AD to address cracks around the potable water and wastewater service panels, which could affect the structural integrity of the fuselage.
You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2025-0009.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from United Airlines who supported the NPRM without change.
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 comment 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 the addition of Note 1 to paragraph (g), 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
EASA AD 2024-0105 specifies procedures for modification of the potable water service panel at stringer (STR) 43 between frames (FRs) 65 and 66 and the wastewater service panel at STR 40 between FRs 65 and 66. Modification includes:
• Removing the solid rivets in both service panels areas;
• Performing a rotating probe test ( i.e., inspection) of the fastener holes for both service panels for any crack;
• If any crack is detected in any service panel, obtaining and following approved repair instructions;
• If any crack is not detected in the potable water service panel, cold working the fastener holes;
• If any crack is not detected in the wastewater service panel, drilling the fastener holes; and
• Installing hi-lok fasteners with interference fit in both service panels.
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 344 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:
| Labor cost | Parts cost | Cost per product | Cost on U.S. operators |
|---|---|---|---|
| 27 work-hours × $85 per hour = $2,295 | $110 | $2,405 | $827,320 |
The FAA has received no definitive data on which to base the cost estimates for the on-condition repair of any crack, as 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.
