ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2019–11–08, which applies to all International Aero Engines, LLC (IAE) PW1133G–JM, PW1133GA–JM, PW1130G–JM, PW1129G–JM, PW1127G–JM, PW1127GA–JM, PW1127G1–JM, PW1124G–JM, PW1124G1–JM, and PW1122G–JM model turbofan engines. AD 2019–11– 08 requires the removal of the main gearbox (MGB) assembly and electronic engine control (EEC) software and the installation of a part and software version eligible for installation for engines that operate on extended operations (ETOPS) flights. The actions in AD 2019–11–08 were interim and only addressed engines that operate on 180-minute or 120-minute ETOPS flights. The FAA now proposes to supersede AD 2019–11–08 to require removal and replacement of the MGB assembly on all affected engines, including engines that do not operate on 180-minute or 120-minute ETOPS flights. This proposed AD would retain all requirements of AD 2019–11–08 for ETOPS engines, and would also require replacement of the affected MGB assembly and EEC software at the next engine shop visit after the effective date of this AD for engines that do not operate on ETOPS flights. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by November 18, 2019.

Discussion The FAA issued AD 2019–11–08, Amendment 39–19654 (84 FR 27511, June 13, 2019), (‘‘AD 2019–11–08’’), for PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 all IAE PW1133G–JM, PW1133GA–JM, PW1130G–JM, PW1129G–JM, PW1127G–JM, PW1127GA–JM, PW1127G1–JM, PW1124G–JM, PW1124G1–JM, and PW1122G–JM model turbofan engines. AD 2019–11– 08 requires the removal of the MGB assembly and EEC software and the installation of a part and software version eligible for installation for engines that operate on ETOPS flights. AD 2019–11–08 resulted from multiple reports of in-flight engine shutdowns (IFSDs) as the result of high-cycle fatigue causing fracture of certain parts of the MGB assembly. The FAA issued AD 2019–11–08 to prevent failure of the MGB assembly. Actions Since AD 2019–11–08 Was Issued The actions in AD 2019–11–08 were interim and only addressed engines that operate on 180-minute or 120-minute ETOPS flights. The FAA now proposes to supersede AD 2019–11–08 to require removal and replacement of the MGB assembly on all affected engines, including engines that do not operate on 180-minute or 120-minute ETOPS flights. The FAA also determined the required actions should be revised to update the required compliance times for engines that operate on 180-minute ETOPS flights to ‘‘before further flight,’’ because the FAA expects that all engines that operate on ETOPS flights have complied with the required actions of AD 2019–11–08. Related Service Information The FAA reviewed PW Service Bulletin (SB) PW1000G–C–72–00–0129– 00A–930A–D, Original Issue, dated April 18, 2019, and PW SB PW1000G– C–73–00–0037–00A–930A–D, Original Issue, dated May 28, 2019. PW SB PW1000G–C–72–00–0129–00A–930A– D, Original Issue, dated April 18, 2019, describes procedures for replacing the IDG oil pump drive gearshaft assembly in the MGB assembly. PW SB PW1000G–C–73–00–0037–00A–930A– D, Original Issue, dated May 28, 2019, describes procedures for replacing the EEC software to incorporate FCS 5.0 software. FAA’s Determination The FAA is proposing this AD because it evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. E:\FR\FM\04OCP1.SGM 04OCP1 Federal Register / Vol. 84, No. 193 / Friday, October 4, 2019 / Proposed Rules Proposed AD Requirements This proposed AD would retain certain requirements of AD 2019–11–08. For engines that operate on 180-minute ETOPS flights, this proposed AD would require replacement of the affected MGB assembly before further flight. For engines that operate on 120-minute ETOPS flights, this proposed AD would require replacement of the affected MGB assembly within 120 days after June 28, 2019 (the effective date of AD 2019–11– 08). This proposed AD would require replacement of the affected MGB assembly at the next engine shop visit after the effective date of this AD for engines that do not operate on ETOPS flights. This proposed AD would also retain the replacement requirement of 53083 EEC software within 120 days after June 28, 2019 (the effective date of AD 2019– 11–08). Costs of Compliance The FAA estimates that this proposed AD affects 72 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 Replace the MGB assembly ........................... Replace the EEC software ............................. 13 work-hours × $85 per hour = $1,105 ........ 3 work-hours × $85 per hour = $255 ............. The new requirements of this proposed AD add no additional economic burden. khammond on DSKJM1Z7X2PROD with PROPOSALS 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division. Regulatory Findings The FAA has 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 VerDate Sep<11>2014 16:19 Oct 03, 2019 Jkt 250001 Parts cost 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 the proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) Will 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. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2019–11–08, Amendment 39–19654 (84 FR 27511, June 13, 2019), and adding the following new AD: ■ International Aero Engines: Docket No. FAA–2019–0614; Product Identifier 2019–NE–14–AD.

SUPPLEMENTARY INFORMATION: Executive Summary Purpose and Authority This proposed rule would amend PBGC’s regulation on rules for administrative review of agency decisions to clarify, simplify, and make other editorial changes to the language, and codify PBGC practices. PBGC’s legal authority for this action comes from section 4002(b)(3) of the Employee Retirement Income Security Act of 1974 (ERISA) which authorizes PBGC to issue regulations to carry out the purposes of title IV of ERISA. Major Provisions The proposed rulemaking would: • Subject all coverage determinations to appeal. • Subject all determinations concerning the allocation of a trusteed plan’s assets upon plan termination to appeal, except for determinations concerning the distribution of residual assets, which would remain subject to reconsideration. • Clarify that, consistent with PBGC’s long-standing practice, when PBGC makes an initial determination effective on the date of issuance, a person aggrieved by the initial determination has no right to request reconsideration or appeal of the determination. • Clarify where to send requests for extensions on appeals and extensions for reconsideration. • Clarify that persons seeking administrative review may request information in PBGC’s possession by using PBGC’s procedures for requests under the Freedom of Information Act and the Privacy Act. Background The Pension Benefit Guaranty Corporation (PBGC) administers two insurance programs for private-sector defined benefit pension plans under title IV of the Employee Retirement Income Security Act of 1974 (ERISA): A single-employer plan termination insurance program and a multiemployer plan insolvency insurance program. The amendments proposed in this rulemaking only apply to the singleemployer program. PBGC is committed to the ongoing retrospective review of its regulations. E:\FR\FM\04OCP1.SGM 04OCP1

Airworthiness Directives; International Aero Engines Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2019-11-08, which applies to all International Aero Engines, LLC (IAE) 
PW1133G-JM, PW1133GA-JM, PW1130G-JM, PW1129G-JM, PW1127G-JM, PW1127GA-
JM, PW1127G1-JM, PW1124G-JM, PW1124G1-JM, and PW1122G-JM model turbofan 
engines. AD 2019-11-08 requires the removal of the main gearbox (MGB) 
assembly and electronic engine control (EEC) software and the 
installation of a part and software version eligible for installation 
for engines that operate on extended operations (ETOPS) flights. The 
actions in AD 2019-11-08 were interim and only addressed engines that 
operate on 180-minute or 120-minute ETOPS flights. The FAA now proposes 
to supersede AD 2019-11-08 to require removal and replacement of the 
MGB assembly on all affected engines, including engines that do not 
operate on 180-minute or 120-minute ETOPS flights. This proposed AD 
would retain all requirements of AD 2019-11-08 for ETOPS engines, and 
would also require replacement of the affected MGB assembly and EEC 
software at the next engine shop visit after the effective date of this 
AD for engines that do not operate on ETOPS flights. The FAA is 
proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by November 
18, 2019.

Discussion

    The FAA issued AD 2019-11-08, Amendment 39-19654 (84 FR 27511, June 
13, 2019), (``AD 2019-11-08''), for all IAE PW1133G-JM, PW1133GA-JM, 
PW1130G-JM, PW1129G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-
JM, PW1124G1-JM, and PW1122G-JM model turbofan engines. AD 2019-11-08 
requires the removal of the MGB assembly and EEC software and the 
installation of a part and software version eligible for installation 
for engines that operate on ETOPS flights. AD 2019-11-08 resulted from 
multiple reports of in-flight engine shutdowns (IFSDs) as the result of 
high-cycle fatigue causing fracture of certain parts of the MGB 
assembly. The FAA issued AD 2019-11-08 to prevent failure of the MGB 
assembly.

Actions Since AD 2019-11-08 Was Issued

    The actions in AD 2019-11-08 were interim and only addressed 
engines that operate on 180-minute or 120-minute ETOPS flights. The FAA 
now proposes to supersede AD 2019-11-08 to require removal and 
replacement of the MGB assembly on all affected engines, including 
engines that do not operate on 180-minute or 120-minute ETOPS flights.
    The FAA also determined the required actions should be revised to 
update the required compliance times for engines that operate on 180-
minute ETOPS flights to ``before further flight,'' because the FAA 
expects that all engines that operate on ETOPS flights have complied 
with the required actions of AD 2019-11-08.

Related Service Information

    The FAA reviewed PW Service Bulletin (SB) PW1000G-C-72-00-0129-00A-
930A-D, Original Issue, dated April 18, 2019, and PW SB PW1000G-C-73-
00-0037-00A-930A-D, Original Issue, dated May 28, 2019. PW SB PW1000G-
C-72-00-0129-00A-930A-D, Original Issue, dated April 18, 2019, 
describes procedures for replacing the IDG oil pump drive gearshaft 
assembly in the MGB assembly. PW SB PW1000G-C-73-00-0037-00A-930A-D, 
Original Issue, dated May 28, 2019, describes procedures for replacing 
the EEC software to incorporate FCS 5.0 software.

FAA's Determination

    The FAA is proposing this AD because it evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would retain certain requirements of AD 2019-11-
08. For engines that operate on 180-minute ETOPS flights, this proposed 
AD would require replacement of the affected MGB assembly before 
further flight. For engines that operate on 120-minute ETOPS flights, 
this proposed AD would require replacement of the affected MGB assembly 
within 120 days after June 28, 2019 (the effective date of AD 2019-11-
08). This proposed AD would require replacement of the affected MGB 
assembly at the next engine shop visit after the effective date of this 
AD for engines that do not operate on ETOPS flights. This proposed AD 
would also retain the replacement requirement of EEC software within 
120 days after June 28, 2019 (the effective date of AD 2019-11-08).

Costs of Compliance

    The FAA estimates that this proposed AD affects 72 engines 
installed on airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

burden.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

Regulatory Findings

    The FAA has 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 that the proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will 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

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.
