SUPPLEMENTARY INFORMATION: khammond on DSKJM1Z7X2PROD with PROPOSALS Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2022–1478; Project Identifier MCAI–2022–00668–E’’ at the beginning of your comments. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend the proposal because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. VerDate Sep<11>2014 16:19 Nov 17, 2022 Jkt 259001 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 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 FAA issued AD 2004–04–09, Amendment 39–13490 (69 FR 9520, March 1, 2004) (AD 2004–04–09), for certain P&WC JT15D–1, JT15D–1A, and JT15D–1B model turbofan engines. AD 2004–04–09 was prompted by three reports of uncontained failure of the impeller. AD 2004–04–09 requires a one-time borescope inspection of the rear face of certain impellers for evidence of a machined groove or step, and repair or replacement of the impeller if a groove or step is found. The FAA issued AD 2004–04–09 to prevent uncontained failure of the impeller and possible damage to the airplane. Actions Since AD 2004–04–09 Was Issued Since the FAA issued AD 2004–04– 09, Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2022– 27, dated June 2, 2022 (Transport Canada AD CF–2022–27), to address an unsafe condition for P&WC JT15D–1, JT15D–1A, and JT15D–1B model turbofan engines. The MCAI states that there has been one recent in-service event of a JT15D–1A engine uncontained failure during a takeoff roll of the airplane. An investigation by P&WC has determined that a crack originated from machining marks on the back face of the impeller and subsequently propagated until the impeller fractured. There is evidence that the event engine had been previously inspected in accordance with P&WC Service Bulletin (SB) No. JT15D– 72–7590, dated May 23, 2003 (mandated by Transport Canada AD CF–2003–17, PO 00000 Frm 00025 Fmt 4702 Sfmt 4702 dated June 23, 2003), but it appears that the machining marks were not detected. P&WC, therefore, published P&WC SB JT15D–72–7655, Original Issue, dated April 14, 2022, to inspect the rear face of the impeller using a new borescope FPI procedure. As a result, Transport Canada issued AD CF–2022–27 to require accomplishment of the borescope FPI at the next hot section inspection until the impeller, part number (P/N) 3020365, is replaced at the next scheduled engine overhaul. This proposed AD was prompted by three prior reports of uncontained failure of the impeller, and one additional recent report of an in-service uncontained failure event. The FAA is proposing this AD to address uncontained failure of the impeller. This condition, if not addressed, could result in fracture of the impeller, subsequent uncontained failure of the engine, and damage to the airplane. See Transport Canada AD CF–2022–27 for additional background information. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1478. 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 the State of Design Authority, the FAA has been notified of the unsafe condition described in the Transport Canada AD. The FAA is issuing this AD after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design. Related Service Information Under 1 CFR Part 51 The FAA reviewed Transport Canada AD CF–2022–27. Transport Canada AD CF–2022–27 specifies instructions for performing a one-time inspection of the rear face of the impeller and replacing the impeller if unacceptable machining witness lines or crack indications are found. Transport Canada AD CF–2022– 27 also specifies instructions for replacing the impeller at the next scheduled engine overhaul. 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 ADDRESSES. Proposed AD Requirements in This NPRM This proposed AD would retain none of the requirements of AD 2004–04–09. This proposed AD would require E:\FR\FM\18NOP1.SGM 18NOP1 Federal Register / Vol. 87, No. 222 / Friday, November 18, 2022 / Proposed Rules accomplishing the actions specified in Transport Canada AD CF–2022–27, described previously. 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 since coordinated with other manufacturers and CAAs to use this process. As a result, the FAA proposes to incorporate by reference Transport Canada AD CF–2022–27 in the FAA final rule. This proposed AD would, therefore, require compliance with Transport Canada AD CF–2022–27 in its entirety through that incorporation. Using common terms that are the same as the heading of a particular section in the Transport Canada AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘Compliance,’’ compliance with this AD requirement is not limited to the section titled ‘‘Corrective Actions’’ in Transport 69233 Canada AD CF–2022–27. Service information required by the Transport Canada AD for compliance will be available at regulations.gov by searching for and locating Docket No. FAA–2022– 1478 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 100 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 Inspect impeller ............................................... Replace impeller ............................................. 6 work-hours × $85 per hour = $510 ............. 30 work-hours × $85 per hour = $2,550 ........ 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. khammond on DSKJM1Z7X2PROD with PROPOSALS 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 16:19 Nov 17, 2022 (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.

ACTION: Advanced notice of proposed rulemaking. AGENCY: SUMMARY: Enforcement and Compliance (E&C), of the Department of Commerce (Commerce), administers the antidumping duty (AD) and countervailing duty (CVD) AD/CVD trade remedy laws of the Tariff Act of 1930, as amended (the Act). Section 773(e) of the Act provides for Commerce to address, in its antidumping calculations, the existence of a particular market situation (PMS), such that the cost of materials and fabrication do not accurately reflect the cost of production in the ordinary course of trade. Commerce seeks public comments as it considers revisiting its PMS methodology and issuing a new regulation that would identify information that Commerce should take into consideration and should not take into consideration in determining whether a PMS exists that distorts the cost of production. Commerce also seeks comments as it considers adjustments to calculations when the amount of distortion in the cost of production caused by a PMS cannot be quantified based on the record before it. DATES: Comments must be received no later than December 18, 2022. ADDRESSES: Submit electronic comments only through the Federal eRulemaking Portal at https:// www.Regulations.gov, Docket No. ITA– 2022–0012. Comments may also be submitted by mail or hand delivery/ courier, addressed to Lisa W. Wang, Assistant Secretary for Enforcement and Compliance, Room 18022, Department of Commerce, 1401 Constitution Ave. NW, Washington, DC 20230. An appointment must be made in advance with the APO/Dockets Unit at (202) 482–4920 to submit comments in person by hand delivery or courier. All comments submitted during the comment period permitted by this document will be a matter of public record and will generally be available on the Federal eRulemaking Portal at PO 00000 Frm 00027 Fmt 4702 Sfmt 4702 https://www.Regulations.gov. Commerce will not accept comments accompanied by a request that part or all of the material be treated confidentially because of its business proprietary nature or for any other reason. Therefore, do not submit confidential business information or otherwise sensitive or protected information. Any questions concerning the process for submitting comments should be submitted to Enforcement & Compliance Communications office at (202) 482– 0063 or ECCommunications@trade.gov. FOR FURTHER INFORMATION CONTACT: Scott McBride at (202) 482–6292 and Hendricks Valenzuela at (202) 482– 4750. SUPPLEMENTARY INFORMATION: Background on Particular Market Situation In 2015, pursuant to the Trade Preferences Extension Act (TPEA), section 771(15) of the Act was amended to provide that Commerce consider sales to be outside the ‘‘ordinary course of trade’’ when there are situations in which Commerce ‘‘determines that the particular market situation prevents a proper comparison with the export price or constructed export price.’’ Further, section 773(e) of the Act was amended to provide that in determining the ‘‘costs of material and fabrication or other processing of any kind employed in producing the merchandise, during a period which would ordinarily permit the production of the merchandise in the ordinary course of trade,’’ for determining constructed value, ‘‘if a particular market situation exists such that the cost of materials and fabrication or other processing of any kind does not accurately reflect the cost of production in the ordinary course of trade,’’ Commerce ‘‘may use another calculation methodology under this subtitle or any other calculation methodology.’’ The Act does not (1) define a particular market situation (‘‘PMS’’), (2) identify the information which Commerce should consider in determining the existence of a PMS that ‘‘does not accurately reflect the costs of production in the ordinary course of trade,’’ or (3) provide Commerce with guidance as to the information which Commerce should consider in determining if a market situation is, or is not, ‘‘particular.’’ The legislative history of the costbased particular market situation reflects that Congress intended for Commerce to not only identify such situations, but to also effectively address them in its calculations.

Airworthiness Directives; Pratt & Whitney Canada Corp. Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2004-04-09, which applies to certain Pratt & Whitney Canada Corp. 
(P&WC) JT15D-1, JT15D-1A, and JT15D-1B model turbofan engines. AD 2004-
04-09 requires a one-time borescope inspection (BSI) of the rear face 
of certain impellers for evidence of a machined groove or step, and 
repair or replacement of the impeller if a groove or step is found. 
Since the FAA issued AD 2004-04-09, the FAA was notified of an 
uncontained failure of an impeller installed on a P&WC JT15D-1A engine 
during takeoff and subsequent investigation by the manufacturer that 
discovered machining marks on the impeller. This proposed AD would 
require borescope fluorescent penetrant inspection (FPI) of the rear 
face of certain impellers for evidence of machining witness lines and, 
depending on the results of the inspection, replacement of the 
impeller, as specified in a Transport Canada AD, which is proposed for 
incorporation by reference (IBR). The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this NPRM by January 3, 2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

agency will also post a report summarizing each substantive verbal 
contact we receive about this proposed AD.

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 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 FAA issued AD 2004-04-09, Amendment 39-13490 (69 FR 9520, March 
1, 2004) (AD 2004-04-09), for certain P&WC JT15D-1, JT15D-1A, and 
JT15D-1B model turbofan engines. AD 2004-04-09 was prompted by three 
reports of uncontained failure of the impeller. AD 2004-04-09 requires 
a one-time borescope inspection of the rear face of certain impellers 
for evidence of a machined groove or step, and repair or replacement of 
the impeller if a groove or step is found. The FAA issued AD 2004-04-09 
to prevent uncontained failure of the impeller and possible damage to 
the airplane.

Actions Since AD 2004-04-09 Was Issued

    Since the FAA issued AD 2004-04-09, Transport Canada, which is the 
aviation authority for Canada, has issued Transport Canada AD CF-2022-
27, dated June 2, 2022 (Transport Canada AD CF-2022-27), to address an 
unsafe condition for P&WC JT15D-1, JT15D-1A, and JT15D-1B model 
turbofan engines. The MCAI states that there has been one recent in-
service event of a JT15D-1A engine uncontained failure during a takeoff 
roll of the airplane. An investigation by P&WC has determined that a 
crack originated from machining marks on the back face of the impeller 
and subsequently propagated until the impeller fractured. There is 
evidence that the event engine had been previously inspected in 
accordance with P&WC Service Bulletin (SB) No. JT15D-72-7590, dated May 
23, 2003 (mandated by Transport Canada AD CF-2003-17, dated June 23, 
2003), but it appears that the machining marks were not detected. P&WC, 
therefore, published P&WC SB JT15D-72-7655, Original Issue, dated April 
14, 2022, to inspect the rear face of the impeller using a new 
borescope FPI procedure. As a result, Transport Canada issued AD CF-
2022-27 to require accomplishment of the borescope FPI at the next hot 
section inspection until the impeller, part number (P/N) 3020365, is 
replaced at the next scheduled engine overhaul.
    This proposed AD was prompted by three prior reports of uncontained 
failure of the impeller, and one additional recent report of an in-
service uncontained failure event. The FAA is proposing this AD to 
address uncontained failure of the impeller. This condition, if not 
addressed, could result in fracture of the impeller, subsequent 
uncontained failure of the engine, and damage to the airplane. See 
Transport Canada AD CF-2022-27 for additional background information.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1478.

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 the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the 
Transport Canada AD. The FAA is issuing this AD after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Transport Canada AD CF-2022-27. Transport Canada 
AD CF-2022-27 specifies instructions for performing a one-time 
inspection of the rear face of the impeller and replacing the impeller 
if unacceptable machining witness lines or crack indications are found. 
Transport Canada AD CF-2022-27 also specifies instructions for 
replacing the impeller at the next scheduled engine overhaul.
    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 ADDRESSES.

Proposed AD Requirements in This NPRM

    This proposed AD would retain none of the requirements of AD 2004-
04-09. This proposed AD would require

[[Page 69233]]

accomplishing the actions specified in Transport Canada AD CF-2022-27, 
described previously.

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 since 
coordinated with other manufacturers and CAAs to use this process. As a 
result, the FAA proposes to incorporate by reference Transport Canada 
AD CF-2022-27 in the FAA final rule. This proposed AD would, therefore, 
require compliance with Transport Canada AD CF-2022-27 in its entirety 
through that incorporation. Using common terms that are the same as the 
heading of a particular section in the Transport Canada AD does not 
mean that operators need comply only with that section. For example, 
where the AD requirement refers to ``Compliance,'' compliance with this 
AD requirement is not limited to the section titled ``Corrective 
Actions'' in Transport Canada AD CF-2022-27. Service information 
required by the Transport Canada AD for compliance will be available at 
regulations.gov by searching for and locating Docket No. FAA-2022-1478 
after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 100 engines installed on airplanes of U.S. Registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs

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

    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.
