is not specifically designated as CBI will be placed in the public 
docket for this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA Emergency AD 2021-0237-E, dated 
November 4, 2021 (EASA AD 2021-0237-E) (also referred to as the MCAI), 
to correct an unsafe condition for certain ATR--GIE Avions de Transport 
R[eacute]gional Model ATR42-200, -300, -320, -400, and -500 airplanes 
and Model ATR72-101, -102, -201, -202, -211, -212, and -212A airplanes. 
ATR--GIE Avions de Transport R[eacute]gional Model ATR42-400 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.
    This AD was prompted by a report that the AMM maintenance procedure 
ATR-A-26-12-60-00ZZZ-281Z-A ``Scheduled Inspection of the Engine Fire 
Detection Loops'' incorrectly described a visual inspection of the fire 
handle. The maintenance procedure specified to verify that the snap 
wire material attaching the fire handle locking hold-plate was a 
stainless steel lockwire where it should have specified either an 
aluminum snap wire or a copper snap wire. If the engine fire handle 
fails, the flightcrew might not be able to extinguish an engine fire 
using the engine fire extinguisher system, which is the primary method 
for extinguishing engine fires. The FAA is issuing this AD to address 
this condition, which, if not detected and corrected, and combined with 
an engine fire, could lead to a failure of the engine fire handle to 
operate, possibly resulting in an uncontrolled engine fire and reduced 
control of the airplane. See the MCAI for additional background 
information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0237-E specifies procedures for a general visual 
inspection of both engine's fire handles for an incorrect snap wire, 
and applicable corrective actions. Corrective actions include removing 
the incorrect snap wire, installing the correct snap wire, and 
installing the safety seal. 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 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, it has notified the FAA of the unsafe condition described in 
the MCAI described above. The FAA is issuing this AD after determining 
that the unsafe condition

[[Page 66157]]

described previously is likely to exist or develop on other products of 
these same type designs.

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2021-0237-E 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 2021-0237-E is incorporated by reference in this AD. This AD 
requires compliance with EASA AD 2021-0237-E 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 2021-0237-E 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 2021-0237-E. Service information required by EASA AD 2021-0237-
E for compliance will be available at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2021-1008 after this AD is 
published.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(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 foregoing notice and comment prior to adoption of this rule 
because if the installation of the incorrect snap wire material on the 
engine's fire handles is not detected and corrected, this condition, 
combined with an engine fire, could lead to a failure of the engine 
fire handle to operate, possibly resulting in an uncontrolled engine 
fire and reduced control of the airplane. In addition, the compliance 
time for the required action 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)(3)(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 forego 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 71 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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................              $0              $85           $6,035
----------------------------------------------------------------------------------------------------------------

    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

                                                             Cost per
            Labor cost                  Parts cost           product

------------------------------------------------------------------------

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

[[Page 66158]]

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.
