Background The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022–0034, dated March 4, 2022 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition on M601D, M601D–1, M601D–2, M601D–11, M601D–11NZ, M601E, M601E–11, M601E–11A, M601E–11AS, M601E– 11S, M601E–21, M601F, M601FS, M601Z, H75–100, H75–200, H80, H80– 100, H80–200, H85–100, and H85–200 engines, all serial numbers. The MCAI states that occurrences of cracks in dilution tube weld areas of the combustion chamber outer liner have been reported. These cracks can lead to crack propagation, possibly resulting in part separation, loss of engine power, and reduced control of the aircraft. As a result of this unsafe condition, the MCAI specifies initial and repetitive BSIs of the dilution tube weld areas of the combustion chamber outer liner and, depending on the outcome of the inspections, corrective action in accordance with the service information. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1239. Related Service Information Under 1 CFR Part 51 The FAA reviewed GEAC Alert Service Bulletin (ASB) ASB–H75–72– 40–00–0056 [01], ASB–M601E–72–40– 00–0113 [01], ASB–H80–72–40–00– 0099 [01], ASB–M601D–72–40–00– 0081[01], ASB–M601F–72–40–00– 0064[01], ASB–M601Z–72–40–00–0063 [01], and ASB–H85–72–40–00–0045 [01], (single document; formatted as service bulletin identifier [revision number]), dated February 16, 2022. This service information specifies procedures for BSIs of the dilution tube weld areas of the combustion chamber outer liner and replacement of the combustion chamber outer liner. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES. 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 and service information described above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require initial and repetitive BSIs of the dilution tube weld areas of the combustion chamber outer liner and, depending on the results of the inspections, corrective action in accordance with the service information. Differences Between This Proposed AD and the MCAI EASA AD 2022–0034 applies to GEAC M601D, M601D–1, M601D–2, M601D– 11, M601D–11NZ, M601E, M601E–11, M601E–11A, M601E–11AS, M601E– 11S, M601E–21, M601F, M601FS, M601Z, H75–100, H75–200, H80, H80– 100, H80–200, H85–100, and H85–200 model turboprop engines, all serial numbers. GEAC M601D, M601D–1, M601D–2, M601D–11NZ, M601E, M601E–21, M601FS, and M601Z model turboprop engines are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this proposed AD therefore does not include those engines in the applicability. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 33 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost BSI of combustion chamber outer liner .......... 2.5 work-hours × $85 per hour = $212.50 ..... The FAA estimates the following costs to do any necessary replacements that would be required based on the Cost per product Parts cost results of the proposed inspection. The agency has no way of determining the $0 Cost on U.S. operators $212.50 $7,012.50 number of aircraft that might need these replacements: jspears on DSK121TN23PROD with PROPOSALS ON-CONDITION COSTS Labor cost On-wing replacement of combustion chamber outer liner. In-shop replacement of combustion chamber outer liner. 64 work-hours × $85 per hour = $5,440 ...................... *$74,909 $80,349 56 work-hours × $85 per hour = $4,760 ...................... 74,909 79,669 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this proposed AD may be VerDate Sep<11>2014 16:01 Sep 26, 2022 Jkt 256001 covered under warranty, thereby reducing the cost impact on affected operators. PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 Parts cost Cost per product Action Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, E:\FR\FM\27SEP1.SGM 27SEP1 58468 Federal Register / Vol. 87, No. 186 / Tuesday, September 27, 2022 / Proposed Rules 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 The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION: Introduction The Commission is issuing this notice of proposed rulemaking to amend its PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 58469 federal sector complaint processing regulations explicitly to authorize the Commission to transmit its hearing and appellate decisions and other documents to registered complainants through the EEOC Electronic Public Portal (hereinafter ‘‘Public Portal’’ or ‘‘Portal’’) in most cases as a matter of course. The proposed rule also requires agencies to notify complainants that they may use the Public Portal to file hearing requests and appeals and communicate with the Commission. When the Commission revised 29 CFR part 1614 in 2012, it added paragraph (g) to § 1614.403. That paragraph generally requires agencies to submit complaint files and appeals to the EEOC’s Office of Federal Operations (‘‘OFO’’) in an acceptable digital format. Paragraph (g) also encourages appellants to submit digital appeals and supporting documents to OFO. The Federal Sector EEO Portal (FedSEP), an electronic portal available only to Federal agencies, was developed after § 1614.403(g) was promulgated. Its use by agencies has resulted in ease of access and communication, increased efficiency, and the elimination of paper. The EEOC’s Public Portal was created after FedSEP and has been in existence for a number of years. Initially, the Public Portal was used by private sector respondents (employers, etc.) to submit certain documents to, and communicate with, the Commission. The Public Portal gradually acquired additional functionality, and private sector charging parties and respondents now use the Portal to communicate with the Commission and submit a wide variety of documents. Similarly, some federal sector complainants accepted the EEOC’s invitation set forth in § 1614.403(g) and use the Public Portal to request hearings, file appeals, and communicate with the EEOC’s Administrative Judges (‘‘AJ’’) and Office of Federal Operations (‘‘OFO’’). Moreover, when a federal sector complainant mails a request for a hearing or an appeal, the AJ or OFO sends a letter acknowledging receipt and encourages the complainant to create a Public Portal account, explaining that documents can be uploaded and accessed using the Portal. In addition, when OFO issues an appellate decision, the decision’s ‘‘Statement of Rights’’ informs the complainant that the complainant may file a request for reconsideration and that the ‘‘[c]omplainant should submit his or her request for reconsideration, and any statement or brief in support of his or her request, via the EEOC Public Portal . . . .’’ (the complainant also is informed that, in lieu of using the E:\FR\FM\27SEP1.SGM 27SEP1

Airworthiness Directives; GE Aviation Czech s.r.o. (Type 
Certificate Previously Held by WALTER Engines a.s., Walter a.s., and 
MOTORLET a.s.) Turboprop Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain GE Aviation Czech s.r.o. (GEAC) M601D-11, M601E-11, M601E-
11A, M601E-11AS, M601E-11S, M601F, H75-100, H75-200, H80, H80-100, H80-
200, H85-100, and H85-200 model turboprop engines. This proposed AD was 
prompted by reports of cracks in dilution tube weld areas of the 
combustion chamber outer liner. This proposed AD would require initial 
and repetitive borescope inspections (BSIs) of the dilution tube weld 
areas of the combustion chamber outer liner and, depending on the 
results of the inspections, replacement of the combustion chamber outer 
liner with a part eligible for installation. The FAA is proposing this 
AD to address the unsafe condition on these products.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
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 NPRM 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 NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI

[[Page 58467]]

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 NPRM. Submissions containing CBI should be sent to 
Barbara Caufield, Aviation Safety Engineer, ECO Branch, FAA, 1200 
District Avenue, Burlington, MA 01803. 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 European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2022-0034, dated March 4, 2022 (referred to after this as ``the 
MCAI''), to correct an unsafe condition on M601D, M601D-1, M601D-2, 
M601D-11, M601D-11NZ, M601E, M601E-11, M601E-11A, M601E-11AS, M601E-
11S, M601E-21, M601F, M601FS, M601Z, H75-100, H75-200, H80, H80-100, 
H80-200, H85-100, and H85-200 engines, all serial numbers. The MCAI 
states that occurrences of cracks in dilution tube weld areas of the 
combustion chamber outer liner have been reported. These cracks can 
lead to crack propagation, possibly resulting in part separation, loss 
of engine power, and reduced control of the aircraft.
    As a result of this unsafe condition, the MCAI specifies initial 
and repetitive BSIs of the dilution tube weld areas of the combustion 
chamber outer liner and, depending on the outcome of the inspections, 
corrective action in accordance with the service information.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1239.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed GEAC Alert Service Bulletin (ASB) ASB-H75-72-40-
00-0056 [01], ASB-M601E-72-40-00-0113 [01], ASB-H80-72-40-00-0099 [01], 
ASB-M601D-72-40-00-0081[01], ASB-M601F-72-40-00-0064[01], ASB-M601Z-72-
40-00-0063 [01], and ASB-H85-72-40-00-0045 [01], (single document; 
formatted as service bulletin identifier [revision number]), dated 
February 16, 2022. This service information specifies procedures for 
BSIs of the dilution tube weld areas of the combustion chamber outer 
liner and replacement of the combustion chamber outer liner.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in ADDRESSES.

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 and service information described above. The FAA is issuing 
this NPRM after determining that the unsafe condition described 
previously is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require initial and repetitive BSIs of the 
dilution tube weld areas of the combustion chamber outer liner and, 
depending on the results of the inspections, corrective action in 
accordance with the service information.

Differences Between This Proposed AD and the MCAI

    EASA AD 2022-0034 applies to GEAC M601D, M601D-1, M601D-2, M601D-
11, M601D-11NZ, M601E, M601E-11, M601E-11A, M601E-11AS, M601E-11S, 
M601E-21, M601F, M601FS, M601Z, H75-100, H75-200, H80, H80-100, H80-
200, H85-100, and H85-200 model turboprop engines, all serial numbers. 
GEAC M601D, M601D-1, M601D-2, M601D-11NZ, M601E, M601E-21, M601FS, and 
M601Z model turboprop engines are not certificated by the FAA and are 
not included on the U.S. type certificate data sheet; this proposed AD 
therefore does not include those engines in the applicability.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 33 engines installed on airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
BSI of combustion chamber outer liner.  2.5 work-hours x $85 per              $0         $212.50       $7,012.50
                                         hour = $212.50.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspection. The agency has no way of determining the number of 
aircraft that might need these replacements:

                                                On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
On-wing replacement of combustion chamber       64 work-hours x $85 per hour =          *$74,909         $80,349
 outer liner.                                    $5,440.
In-shop replacement of combustion chamber       56 work-hours x $85 per hour =            74,909          79,669
 outer liner.                                    $4,760.
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I,

[[Page 58468]]

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
