Background
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, has issued
EASA Emergency AD 2025-0230-E, dated October 21, 2025 (EASA Emergency
AD 2025-0230-E) (also referred to as the MCAI), to correct an unsafe
condition on Textron Aviation Inc. Model 182M, 182N, 182P, 182Q, 182R,
all serial numbers, and (Reims-manufactured) F182P and F182Q airplanes,
all serial numbers, if modified in accordance with EASA Supplemental
Type Certificate (STC) 10013975 at Revision 15 or earlier, or
(formerly) STC EASA.A.S.00774 (installation of Engine SMA SR305-230 or
SR305-230E); and Model 182Q, 182R, all serial numbers, if modified in
accordance with EASA STC 10016495 at Revision 1 or earlier, or
(formerly) STC EASA.IM.A.S.02857, (installation of Engine SMA SR305-
230/-230-1). The MCAI states that occurrences were reported of damaged
intercooler air hoses. The MCAI also states that EASA Emergency AD
2025-0230-E is considered an interim action and further AD action may
follow. This condition, if not detected and corrected, could result in
a loss of manifold pressure and consequent loss of engine power,
potentially leading to a forced landing, damage to the airplane, and
injury to occupants.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2025-4001.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed SMA Aero Engines GmbH Service Bulletin SB-C182-71-
011, Revision No. 01, dated October 20, 2025, which specifies
procedures for repetitive visual inspections of the intercooler inlet
and outlet hoses for cracks and specifies replacement of any
intercooler air hose found cracked. 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 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.
AD Requirements
This AD requires accomplishing the actions specified in the
material already described.
Differences Between This AD and the MCAI
The MCAI applies to certain Textron Aviation Inc. Model 182M, 182N,
182P, 182Q, 182R and (Reims-manufactured) F182P and F182Q airplanes.
This AD does not apply to Models 182M, 182N,182P, and (Reims-
manufactured) F182P and F182Q airplanes because EASA STC 10013975 is
currently not validated in the United States.
Interim Action
The FAA considers that this AD is an interim action. If final
action is later identified, the FAA might consider further rulemaking
then.
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 damaged intercooler inlet and outlet hoses could result in a
loss of manifold pressure. The consequent loss of engine power could
lead to a forced landing, damage to the airplane, and injury to
occupants, and thus an inspection of these parts is required before
further flight. In addition, most of the affected airplanes have
already accumulated or are approaching 500 flight hours and thus the
mandatory replacement is required either before further flight or
within 50 flight hours of operation. These compliance times are 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
The requirements of the Regulatory Flexibility Act (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 prior notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 10 airplanes of U.S.
registry.
The FAA estimates the following costs to comply with 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.
