Airworthiness Directives; International 

Aero Engines, LLC 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 International Aero Engines, LLC 

(IAE) Model PW1124G1–JM, PW1127G– 

JM, PW1127GA–JM, PW1129G–JM, 

PW1130G–JM, PW1133G–JM, and 

PW1133GA–JM engines. This proposed 

AD was prompted by a report that 

certain high-pressure compressor (HPC) 

2nd stage rotors and HPC 4th stage 

rotors have potentially degraded knifeedge seals and abrasive coating of the 

rear wing 4th stage rotor due to having 

been cleaned in alkaline solution 

without masking the knife-edge seal 

coating. Operating in this condition 

could result in material degradation and 

fracture of the HPC 2nd stage rotor and 

HPC 4th stage rotor. This proposed AD 

would require replacement of certain 

HPC 2nd stage rotors and HPC 4th stage 

rotors. 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 20, 

2023. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

regulations.gov. Follow the instructions 

for submitting comments.

SUPPLEMENTARY INFORMATION: 

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–2023–1989; Project Identifier AD– 

2023–00512–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 this 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 received 

about this NPRM. 

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 Mark Taylor, Aviation 

Safety Engineer, FAA, 2200 South 216th 

Street, Des Moines, WA 98198. 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 was notified that on certain 

IAE Model PW1124G1–JM, PW1127G– 

JM, PW1127GA–JM, PW1129G–JM, 

PW1130G–JM, PW1133G–JM, and 

PW1133GA–JM engines, a batch of HPC 

2nd stage rotors and HPC 4th stage 

rotors could have degraded knife-edge 

seals and abrasive coating on the rear 

wing 4th stage rotor due to having been 

cleaned in alkaline solution without 

masking the knife-edge seal coating. 

Operating in this condition could result 

in material degradation and fracture of 

the HPC 2nd stage rotor and HPC 4th 

stage rotor. This condition, if not 

addressed, could result in uncontained 

part release or dual-engine shutdown, 

damage to the engine, damage to the 

airplane, and loss of the airplane. 

FAA’s Determination 

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. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Pratt & Whitney 

Service Bulletin (SB) PW1000G–C–72– 

00–0208–00A–930A–D, Issue 001, dated 

September 13, 2022. This service 

information identifies the affected HPC 

2nd stage rotors and HPC 4th stage 

rotors and specifies procedures for 

inspection and repair of the HPC 2nd 

stage rotors and HPC 4th stage rotors. 

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. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

replacement of the affected HPC 2nd 

stage rotor and HPC 4th stage rotor with 

parts eligible for installation. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 6 

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 Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replace HPC 2nd stage rotor and HPC 4th 

stage rotor with repaired parts.

73 work-hours × $85 per hour = $6,205 ........ $0 $6,205 $37,230 

Operators may choose to use new 

parts instead of repaired parts to comply 

with this proposed AD. For replacement 

with new parts, the FAA estimates the 

following costs:

Replace HPC 4th stage rotor ....................................... 32 work-hours × $85 per hour = $2,720 ...................... 244,000 246,720 

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. 

The Proposed Amendment

Airworthiness Directives; ATR—GIE 

Avions de Transport Re ́gional 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–17–02, which applies to all ATR— 

GIE Avions de Transport Re ́gional 

Model ATR42–200, –300, and –320 

airplanes. AD 2021–17–02 requires a 

one-time inspection for discrepancies of 

the wire bundles between the left- and 

right-hand angle of attack (AOA) probes 

and the crew alerting computer, and, 

depending on findings, applicable 

corrective actions. AD 2021–17–02 also 

required for certain airplanes, modifying 

the captain stick shaker wiring, and for 

all airplanes, revising the existing 

aircraft flight manual (AFM) and 

applicable corresponding operational 

procedures to incorporate procedures 

for the stick pusher/shaker. Since the 

FAA issued AD 2021–17–02, a 

modification was developed to the 

affected wiring. This proposed AD 

would require installing a new AOA 

power supply unit and revising the 

existing AFM, as specified in a 

European Union Aviation Safety Agency 

(EASA) 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 proposed AD by November 20, 

2023. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
