SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus SAS Model 
A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model 
A320 series airplanes; Model A321-211, -212, -213, -231, -232, -251N, -
251NX, -252N, -252NX, -253N, -253NX, -253NY, -271N, -271NX, -272N, and 
-272NX airplanes; Airbus SAS Model A330-200 series airplanes; Model 
A330-300 series airplanes; Model A330-800 series airplanes; Model A330-
900 series airplanes; Model A350-941 and -1041 airplanes; and Model 
A380-800 series airplanes. The NPRM published in the Federal Register 
on December 31, 2024 (89 FR 107063). The NPRM was prompted by AD 2024-
0199, dated October 18, 2024 (EASA AD 2024-0199) (also referred to as 
the MCAI), issued by EASA, which is the Technical Agent for the Member 
States of the European Union. The MCAI states that corrosion and cracks 
were found on the broadband antenna adapter plate during an inspection. 
Further investigation determined that the broadband antenna adapter 
plate and skirt assembly-adapter are made of material susceptible to 
corrosion cracking, and that the recommended maintenance programs do 
not ensure timely detection of cracks and damage in this area.
    In the NPRM, the FAA proposed to require repetitive general visual 
inspections of the broadband antenna adapter plate, skirt, vents, and 
attachment fittings and applicable corrective actions, and limit the 
installation of affected parts under certain conditions, as specified 
in EASA AD 2024-0199. The NPRM also proposed to require reporting of 
the inspection results after each inspection, as specified in EASA AD 
2024-0199. The FAA is issuing this AD to address the corrosion and 
cracks on the broadband antenna adapter plate and skirt assembly-
adapter. The unsafe condition, if not addressed, could lead to in-
flight detachment of the radome, antenna, and affected parts (e.g., the 
broadband antenna adapter plate, skirt, vents and attachment fittings), 
which could impact the tail section of the airplane, possibly resulting 
in damage and reduced control of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2718.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from an individual who supported the 
NPRM without change.

Clarification of Paragraph (h)(4) of the Proposed AD

    The FAA revised paragraph (h)(4) of this AD to clarify the 
conditions that require corrective actions.

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 any other changes described previously, 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 2024-0199 specifies procedures for repetitive general 
visual inspections for cracks and corrosion of the broadband antenna 
adapter plate, skirt, vents, and attachment fittings, and, depending on 
findings, corrective actions including repair or replacement of the 
affected parts. EASA AD 2024-0199 also limits the installation of 
affected parts under certain conditions and requires reporting of both 
positive and negative inspection results after the initial inspection 
and thereafter reporting the positive inspection results after each 
subsequent inspection. 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.

Interim Action

    The FAA considers that this AD is an interim action. The FAA 
anticipates that further AD action will follow.

Costs of Compliance

    The FAA estimates that this AD affects 4 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
             Labor cost                Parts cost         Cost per product             Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 61 work-hours x $85 per hour =           $0  Up to $5,185..................  Up to $20,740.
 $5,185.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any 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 22459]]



                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
           Labor cost                 Parts cost       Cost per product
------------------------------------------------------------------------
50 work-hours x $85 per hour =              $10,000             $14,250
 $4,250.........................
------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the repairs specified in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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.
