Airworthiness Directives; Airbus SAS Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to supersede Airworthiness Directive (AD) 2022-24-05, which applies to all Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2022-24-05 requires repetitive inspections of certain galleys for corrosion of trolley retainer aluminum blocks and delamination of the upper panel of the trolley compartment, and applicable corrective action. Since the FAA issued AD 2022-24-05, the list of affected galleys has been revised, and a modification has been developed to restore the design integrity of the affected galleys. This proposed AD would continue to require the actions in AD 2022-24-05, provide optional terminating action for the repetitive inspections, revise the list of affected parts, and prohibit the installation of affected parts under certain conditions, as specified in a European Union Aviation Safety Agency (EASA). The FAA is proposing this AD to address the unsafe condition on these products.

Background

The FAA issued AD 2022-24-05, Amendment 39-22245 (87 FR 74291, December 5, 2022) (AD 2022-24-05), for all Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -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. AD 2022-24-05 was prompted by an MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2021-0183R1, dated September 20, 2021, to correct an unsafe condition.

AD 2022-24-05 requires repetitive inspections of certain galleys for corrosion of trolley retainer aluminum blocks and delamination of the upper panel of the trolley compartment, and applicable corrective actions. The FAA issued AD 2022-24-05 to address damage that could affect the galley's capability to hold the trolley under emergency landing loads, which could lead to trolley detachment, possibly resulting in blocking of an escape path during an emergency exit.

Actions Since AD 2022-24-05 Was Issued

Since the FAA issued AD 2022-24-05, EASA superseded EASA AD 2021-0183R1, dated September 20, 2021, and issued EASA AD 2024-0038, dated February 5, 2024 (EASA AD 2024-0038) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. EASA AD 2024-0038 states that the list of affected galleys has been revised, and Airbus and the galley manufacturer have developed a modification to restore the design integrity of the affected galleys.

The FAA is proposing this AD to detect and correct damage that could affect the galley's capability to hold the trolley under emergency landing loads, which could lead to trolley detachment, possibly resulting in blocking of an escape path during an emergency exit.

The FAA is proposing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2024-1890.

Explanation of Retained Requirements

Although this proposed AD does not explicitly restate the requirements of AD 2022-24-05, this proposed AD would retain all of the requirements of AD 2022-24-05. Those requirements are referenced in EASA AD 2024-0038, which, in turn, is referenced in paragraph (g) of this proposed AD.

Material Incorporated by Reference Under 1 CFR Part 51

EASA AD 2024-0038 includes the following provisions:

• Procedures for repetitive general visual inspections of certain galleys for discrepancies including corrosion of trolley retainer aluminum blocks and delamination of upper panel of trolley compartment;
• Corrective actions including repeating the inspection at an earlier interval, repairing the trolley compartment upper panel, and limiting the trolley weight;
• Procedures for modifying the affected galleys as optional terminating action for the repetitive inspections;
• A revised the list of affected galleys; and
• Prohibition of the installation of affected parts unless the parts are inspected and corrected.

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

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 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 require accomplishing the actions specified in EASA AD 2024-0038 described previously, except for any differences identified as exceptions in the regulatory text 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 incorporate EASA AD 2024-0038 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024-0038 in its entirety 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 2024-0038 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 AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in EASA AD 2024-0038. Material required by EASA AD 2024-0038 for compliance will be available at regulations.gov under Docket No. FAA-2024-1890 after the FAA final rule is published.

Costs of Compliance

The FAA estimates that this AD, if adopted as proposed, would affect 1,425 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:

The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions:

The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators.

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.
