Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes; Model A330-200, -200 Freighter, -300, -800, and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of trimmable horizontal stabilizer actuators (THSAs) being delivered to operators having erroneous information (accumulated life) in the authorized release certificate. This AD requires contacting Collins Aerospace for amended authorized release certificates for the affected parts and replacing the affected parts if necessary, and prohibits the installation of affected parts, 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.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2024-0247, dated December 18, 2024
(EASA AD 2024-0247) (also referred to as the MCAI), to correct an
unsafe condition for all Airbus SAS Model A318 and A319 series
airplanes; Model A320-211, 212, -214, -215, -216, -231, -232, -233, -
251N, -252N, -253N, -271N, -272N, and -273N airplanes; Model A321
series airplanes; Model A330-201, -202, -203, -223, -243, -223F, -243F,
-301, -302, -303, -321, -322, -323, -341, -342, -343, -743L, -841, and
-941 airplanes; and Model A340-211, -212, -213, -311, -312, -313, -541,
-542, -642, and -643 airplanes. Model A320-215, A330-743L, A340-542,
and A340-643 airplanes are not certificated by the FAA and are not
included on the U.S. type certificate data sheet; this AD therefore
does not include those airplanes in the applicability. The MCAI states
that occurrences were reported of THSAs delivered to operators having
erroneous information (accumulated life) in the authorized release
certificates. These THSAs were released to service between 2014 and
2024 at some Collins Aerospace Maintenance, Repair, and Overhaul (MRO)
facilities where the THSA screw jack assemblies were replaced with
parts having higher cumulative operating life than was documented on
the authorized release certificates.
The FAA is issuing this AD to address erroneous accumulated life
information in the THSA release certificate, which could lead to
operation of the THSA beyond the certificated life limit; operation of
the THSA beyond the certificated life limit could result in failure of
the THSA and consequent reduced controllability of the airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2025-0198.
Material Incorporated by Reference Under 1 CFR Part 51
EASA AD 2024-0247 specifies procedures for contacting Collins
Aerospace for approved instructions for obtaining amended authorized
release certificates, which will allow operators to correctly manage
the maintenance consequences of erroneous accumulated life values and
ensure compliance with ADs and required airworthiness limitations
(Airworthiness Limitations Section (ALS) Part 4). EASA AD 2024-0247
also specifies procedures for replacement of affected THSAs and
prohibits the installation of affected THSAs.
This AD also requires Collins Aerospace Vendor Service Information
Letter FA3T1-27-04, dated August 6, 2024, which provides a list of
affected THSAs that were repaired at Collins Aerospace MRO facilities
between 2014 and 2024 and released with incorrect authorized release
certificates containing erroneous accumulated life values.
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 and
material referenced above. The FAA is issuing this AD after determining
that the unsafe condition described previously is likely to exist or
develop on other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in the
material described previously, except for any differences identified as
exceptions in the regulatory text of this 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,
EASA AD 2024-0247 is incorporated by reference in this AD. This AD
requires compliance with EASA AD 2024-0247 in its entirety through that
incorporation, except for any differences identified as exceptions in
the regulatory text of this AD. Using common terms that are the same as
the heading of a particular section in EASA AD 2024-0247 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
2024-0247. Material required by EASA AD 2024-0247 for compliance will
be available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2025-0198 after
this AD is published.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C.
551 et seq.) authorizes agencies to dispense with notice and comment
procedures for rules when the agency, for ``good cause,'' finds that
those procedures are ``impracticable, unnecessary, or contrary to the
public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because erroneous accumulated life
[[Page 9288]]
values could significantly affect the operator's ability to accurately
manage compliance with ADs and ALS Part 4 (airworthiness limitations)
and cause operation of the THSA beyond the certificated life limit,
which could result in failure of the THSA and consequent reduced
controllability of the airplane. Accordingly, notice and opportunity
for prior public comment are impracticable and contrary to the public
interest pursuant to 5 U.S.C. 553(b).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forgo notice and
comment.
Regulatory Flexibility Act (RFA)
The requirements of the RFA do not apply when an agency finds good
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and
comment. Because the FAA has determined that it has good cause to adopt
this rule without notice and comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 2,087 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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............ $0 $85 $177,395
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition replacement
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, and
(2) Will not affect intrastate aviation in Alaska.

2024-0247).
(h) Exceptions to EASA AD 2024-0247
(1) Where EASA AD 2024-0247 refers to its effective date, this
AD requires using the effective date of this AD.
(2) Where EASA AD 2024-0247 defines a serviceable part as ``A
THSA eligible for installation in accordance with Airbus
instructions,'' this AD requires replacing that text with ``A THSA
eligible for installation.''
(3) Where EASA AD 2024-0247 defines ``the VSIL,'' for this AD,
operators must use Collins Aerospace Vendor Service Information
Letter FA3T1-27-04, dated August 6, 2024.
[[Page 9289]]
(4) This AD requires replacing Note 1 of EASA AD 2024-0247 with
``If no approved instructions are provided within the compliance
time of paragraph (1) of this AD, paragraph (2) of this AD must be
accomplished before further flight. The affected part is eligible to
be considered a serviceable part based on the content of the Collins
Aerospace approved instructions, once received and accomplished, as
required in paragraph (1) of this AD.''
(5) This AD does not adopt the ``Remarks'' section of EASA AD
2024-0247.
(i) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-
520, Continued Operational Safety Branch, FAA, has the authority to
