Airworthiness Directives; Airbus SAS Airplanes

Issuing agencies

Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a girt bar fitting safety hook on an airplane in the production line was found stuck in the upward position due to excessive sealant applied between the girt bar fitting and door mat. This proposed AD would require a detailed inspection of each affected part and applicable corrective actions, and provide additional requirements for maintenance. The FAA is proposing this AD to address the unsafe condition on these products.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2025-0244, dated October 30, 2025 
(EASA AD 2025-0244) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A350-941 and -1041 airplanes. 
The MCAI states that a girt bar fitting safety hook on an airplane in 
the production line was found stuck in the upward position due to 
excessive sealant applied between the girt bar fitting and door mat. 
Investigations confirmed the root cause as excessive sealant 
application, causing mechanical interference with the safety hook's 
range of motion. This condition, if not detected and corrected, could 
lead to girt bar disengagement from the girt bar fitting assembly with 
consequent passenger door slide deployment failure during an emergency, 
possibly preventing safe evacuation of airplane occupants.
    The FAA is proposing this AD to address the unsafe condition on 
these products.
    You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under 
Docket No. FAA-2026-11802.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2025-0244 specifies procedures for a detailed inspection of 
each affected part (passenger/crew door girt bar fitting assembly) for 
discrepancies and applicable corrective actions, and provides 
additional requirements for maintenance. Discrepancies include a safety 
hook that is stuck in the upward position or obstructed by excessive 
sealant. Corrective action includes removing excessive sealant and 
applying a thin layer of sealant. The maintenance requirement prohibits 
the use of certain maintenance procedure (MP) tasks. 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 require accomplishing the actions specified 
in EASA AD 2025-0244 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 2025-0244 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2025-0244 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 2025-0244 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 2025-
0244. Material required by EASA AD 2025-0244 for compliance will be 
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2026-11802 after the 
FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 38 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                  Estimated Costs for Required Actions
------------------------------------------------------------------------
                                               Cost per    Cost on U.S.
          Labor cost             Parts cost    product       operators
------------------------------------------------------------------------
1 work-hour x $85 per hour =            $0          $85          $3,230
 $85..........................
------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition action 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 this on-condition action:

[[Page 64317]]



                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
           Labor cost                 Parts cost       Cost per product
------------------------------------------------------------------------
1 work-hour x $85 per hour = $85  Negligible........  $85 per door.
 per door.
------------------------------------------------------------------------

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.
