and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Brenda 
Buitrago Perez, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, 
Suite 410, Westbury, NY 11590; telephone 516-288-7368; email 
[email protected]. Any commentary that the FAA receives 
which is not specifically designated as CBI will be placed in the 
public docket for this rulemaking.

Background

    The Civil Aviation Authority (CAA), which is the aviation authority 
for the United Kingdom (UK), has issued UK CAA AD G-2025-0002, dated 
April 11, 2025; corrected April 25, 2025 (UK CAA AD G-2025-0002) (also 
referred to as the MCAI), to correct an unsafe condition on certain 
Ipeco pilot and co-pilot seats. The MCAI states that occurrences were 
reported of unexpected rearward movement of pilot and co-pilot seats 
during take-off and landing. Investigations originally determined that 
horizontal guide block wear, presence of burrs on horizontal center 
track, and horizontal track lock system weakness (spring tension too 
low) were causes which contributed to the seat not being correctly 
locked. The original unsafe condition was addressed through UK CAA AD 
G-2022-0011, dated June 9, 2022, (which corresponds with FAA AD 2023-
14-10, Amendment 39-22510, dated August 3, 2023 (88 FR 51230) (FAA AD 
2023-14-10)). However, the incorrect distribution of

[[Page 24960]]

the stops and packers during the modification required by FAA AD 2023-
14-10 has been found to cause the seat not to positively lock in 
position because of the unequal re-installation of the stops and 
packers onto the fore/aft tubes during seat reassembly, which can 
result in unexpected rearward movement of pilot and co-pilot seats 
during take-off and landing.
    The FAA is issuing this AD to address the unsafe condition on these 
products, which, if not corrected, could lead to further cases of 
unwanted flight crew seat movement, which could result in reduced 
control of the airplane, a rapid descent of the airplane, and serious 
injury to passengers and crew. You may examine the MCAI in the AD 
docket at regulations.gov under Docket No. FAA-2025-1101.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Ipeco Service Bulletin 063-25-20, Issue 1, dated 
March 25, 2025. This material describes procedures to conduct a one-
time visual inspection of each affected seat, and if any incorrect 
installation is found (stops or packers), remove and install the stops 
and packers, and perform operational tests of the seats. 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 Ipeco 
material described previously. See ``Differences Between This AD and 
the MCAI'' for a discussion of the general differences included in this 
AD.

Differences Between This AD and the MCAI

    UK CAA AD G-2025-0002, dated April 11, 2025; corrected April 25, 
2025, does not mention Part C of the Accomplishment Instructions of 
Ipeco Service Bulletin 063-25-20, Issue 1, dated March 25, 2025. This 
AD, however, requires the accomplishment of Part C of the 
Accomplishment Instructions of Ipeco Service Bulletin 063-25-20, Issue 
1, dated March 25, 2025. The FAA has coordinated this change with the 
UK CAA.

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 movement of the pilot and co-pilot seats during take-off and 
landing could result in reduced control of the airplane, a rapid 
descent of the airplane, and serious injury to passengers and crew. 
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

    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 120 appliances installed on, 
but not limited to, ATR-GIE Avions de Transport R[eacute]gional Model 
ATR42 and ATR72 airplanes. 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
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170............                 $0                $170                   $20,400
----------------------------------------------------------------------------------------------------------------

    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:

                                     Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
                            Labor cost                                  Parts cost          Cost per product
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85..................................               $420                      $505
----------------------------------------------------------------------------------------------------------------

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.
