Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada Emergency AD CF–2023–12, dated February 23, 2023 (Transport Canada Emergency AD CF– 2023–12) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus Canada Limited Partnership Model BD–500–1A10 and BD–500–1A11 airplanes. The MCAI states that since early 2021, there have been several unscheduled PW1500G engine removals due to CAS message L/R ENGINE FAULT with associated INFO message OIL DEBRIS ABOVE LIMIT being displayed, high vibration, or debris found on the magnetic chip collector of bearing compartment No. 3 (BC3). The investigation by Pratt & Whitney found that in most instances, the No. 3 bearings originated from a single manufacturing lot that have a possible defect. In December 2022, an airplane experienced engine stall and uncommanded in-flight shutdown (IFSD) while in cruise. Prior to the IFSD event, the airplane had received advisory-level CAS message R ENGINE FAULT with associated INFO message 79 R ENGINE FAULT–OIL DEBRIS ABOVE LIMIT during the previous flight, and the fault was deferred in accordance with the approved minimum equipment list (MEL). The No. 3 bearing installed on the event engine was found to be from the suspect lot, and post-event inspection found metallic debris on the BC3 chip collector. E:\FR\FM\04APR1.SGM 04APR1 19816 Federal Register / Vol. 88, No. 64 / Tuesday, April 4, 2023 / Rules and Regulations This AD is intended to prevent a No. 3 bearing failure. This condition, if not addressed, could result in unrecoverable engine failure or power loss for both engines and consequent reduced control of the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–0658. Related Service Information Under 1 CFR Part 51 Transport Canada Emergency AD CF– 2023–12 prohibits dispatch of an airplane with an affected engine having an applicable CAS message displayed, unless the BC3 chip collector and oil filter are inspected and any debris found is dispositioned. 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 described 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 Transport Canada Emergency AD CF–2023–12 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, Transport Canada Emergency AD CF–2023–12 is incorporated by reference in this AD. This AD requires compliance with Transport Canada Emergency AD CF– 2023–12 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 Transport Canada Emergency AD CF– 2023–12 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 sections titled ‘‘Compliance’’ and ‘‘Corrective Actions’’ in Transport Canada Emergency AD CF–2023–12. 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 forgoing notice and comment prior to adoption of this rule because a No. 3 bearing failure could result in unrecoverable engine failure or power loss for both engines and consequent reduced control 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)(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 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 84 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 × $85 per hour = $85 .............................................................................................. $0 $85 $7,140 The FAA estimates it would take 2 hours for any required inspection and debris disposition at $85 per hour, for a total cost of $170 per engine. ddrumheller on DSK120RN23PROD with RULES1 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. VerDate Sep<11>2014 17:05 Apr 03, 2023 Jkt 259001 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 PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 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. E:\FR\FM\04APR1.SGM 04APR1 Federal Register / Vol. 88, No. 64 / Tuesday, April 4, 2023 / Rules and Regulations 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.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada Emergency AD CF-2023-12, dated February 23, 
2023 (Transport Canada Emergency AD CF-2023-12) (also referred to as 
the MCAI), to correct an unsafe condition for certain Airbus Canada 
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes.
    The MCAI states that since early 2021, there have been several 
unscheduled PW1500G engine removals due to CAS message L/R ENGINE FAULT 
with associated INFO message OIL DEBRIS ABOVE LIMIT being displayed, 
high vibration, or debris found on the magnetic chip collector of 
bearing compartment No. 3 (BC3). The investigation by Pratt & Whitney 
found that in most instances, the No. 3 bearings originated from a 
single manufacturing lot that have a possible defect.
    In December 2022, an airplane experienced engine stall and 
uncommanded in-flight shutdown (IFSD) while in cruise. Prior to the 
IFSD event, the airplane had received advisory-level CAS message R 
ENGINE FAULT with associated INFO message 79 R ENGINE FAULT-OIL DEBRIS 
ABOVE LIMIT during the previous flight, and the fault was deferred in 
accordance with the approved minimum equipment list (MEL). The No. 3 
bearing installed on the event engine was found to be from the suspect 
lot, and post-event inspection found metallic debris on the BC3 chip 
collector.

[[Page 19816]]

    This AD is intended to prevent a No. 3 bearing failure. This 
condition, if not addressed, could result in unrecoverable engine 
failure or power loss for both engines and consequent reduced control 
of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0658.

Related Service Information Under 1 CFR Part 51

    Transport Canada Emergency AD CF-2023-12 prohibits dispatch of an 
airplane with an affected engine having an applicable CAS message 
displayed, unless the BC3 chip collector and oil filter are inspected 
and any debris found is dispositioned. 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 
described 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 Transport 
Canada Emergency AD CF-2023-12 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, 
Transport Canada Emergency AD CF-2023-12 is incorporated by reference 
in this AD. This AD requires compliance with Transport Canada Emergency 
AD CF-2023-12 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 Transport Canada Emergency AD CF-2023-12 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 sections 
titled ``Compliance'' and ``Corrective Actions'' in Transport Canada 
Emergency AD CF-2023-12.

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 forgoing notice and comment prior to adoption of this rule 
because a No. 3 bearing failure could result in unrecoverable engine 
failure or power loss for both engines and consequent reduced control 
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)(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 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 84 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           $7,140
----------------------------------------------------------------------------------------------------------------

    The FAA estimates it would take 2 hours for any required inspection 
and debris disposition at $85 per hour, for a total cost of $170 per 
engine.

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.

[[Page 19817]]

    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.

List of Subjects in 14 CFR Part 39
