rulemaking.
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2025-0167, dated July 30, 2025 (EASA
AD 2025-0167) (also referred to as the MCAI), to correct an unsafe
condition for all Airbus SAS Model A318-111, -112, -121, and -122
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, -
151N, -153N, -171N, and -173N airplanes; Model A320-211, -212, -214, -
215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -
273N airplanes; Model A321-111, -112, -131, -211, -212, -213, -231, -
232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -253NY, -271N, -
271NX, -271NY, -272N, and -272NX airplanes. Model A320-215 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 it was determined
that a batch of MLG aft pintle pins having Part Number (P/N)
D3215600500600 or P/N D3215303000800 did not have nickel plating
applied to the inner bore during manufacturing. The unsafe condition,
if not corrected, could lead to the development of corrosion with
potential crack initiation in the affected parts, possibly resulting in
a MLG collapse, with consequent damage to the airplane and injury to
occupants.
The FAA is issuing 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-2025-2268.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed EASA AD 2025-0167, which specifies procedures to
replace affected MLG pintle pins having Part Number P/N D3215600500600
or P/N D3215303000800 with a serviceable part. EASA AD 2025-0167 also
prohibits the installation of affected parts. 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 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 EASA AD
2025-0167 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 2025-0167 is incorporated by reference in this AD. This AD
requires compliance with EASA AD 2025-0167 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 2025-0167 does not mean
that
[[Page 42314]]
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-
0167. Material required by EASA AD 2025-0167 for compliance will be
available at regulations.gov under Docket No. FAA-2025-2268 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 MLG aft pintle pins that do not have nickel plating applied to
the inner bore could lead to the development of corrosion with
potential crack initiation in the affected parts, possibly resulting in
a MLG collapse, consequent damage to the airplane and injury to
occupants. Additionally, the compliance time in this AD is shorter than
the time necessary for the public to comment and for publication of the
final rule. 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 1,945 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
------------------------------------------------------------------------
35 work-hours x $85 per hour $14,000 $16,975 $305,550 (Up to
= $2,975. 18 airplanes
*).
------------------------------------------------------------------------
* Only airplanes with affected parts must do the replacement. There are
only 18 affected parts.
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.
