Airworthiness Directives; General 

Electric Company Turbofan 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 General Electric Company (GE) 

GEnx-2B67/P model turbofan engines. 

This proposed AD was prompted by the 

detection of an iron inclusion in a 

forging, which may reduce the fatigue 

life of certain low-pressure turbine rotor 

(LPTR) stage 4 disks and LPTR stage 6 

disks. This proposed AD would require 

the removal of certain LPTR stage 4 

disks and LPTR stage 6 disks from 

service and replacement with parts 

eligible for installation. 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 August 8, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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–2022–0587; Project Identifier AD– 

2022–00394–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 https://

www.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 Alexei Marqueen, 

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 was notified by the engine 

manufacturer of the detection of an iron 

inclusion in a forging, which may 

reduce the fatigue life of certain LPTR 

stage 4 disks and LPTR stage 6 disks. 

The manufacturer’s investigation 

determined that the inclusion is a meltrelated defect and that, as a result of the 

inclusion forming in the forging, certain 

LPTR stage 4 disks and LPTR stage 6 

disks may have reduced material 

properties and a lower fatigue life 

capability. Reduced material properties 

may cause premature LPTR stage 4 disk 

and LPTR stage 6 disk fracture, which 

could result in uncontained debris 

release. As a result of its investigation, 

the manufacturer published service 

information that specifies procedures 

for the removal and replacement of 

certain LPTR stage 4 disks and LPTR 

stage 6 disks installed on GEnx–2B67/P 

model turbofan engines. This condition, 

if not addressed, could result in 

uncontained debris release, damage to 

the engine, and damage to 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 

The FAA reviewed GE GEnx-2B 

service bulletin (SB) 72–0448 R00, dated 

February 7, 2022. This SB describes 

procedures for removing the affected 

LPTR stage 4 disks and LPTR stage 6 

disks from service. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require the 

removal and replacement of certain 

LPTR stage 4 disks and LPTR stage 6 

disks. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 4 

engines installed on airplanes of U.S. 

registry. The FAA estimates that the 

affected disk population on engines 

installed on airplanes of U.S. registry 

would include three LPTR stage 4 disks 

and one LPTR stage 6 disk. 

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 the LPTR stage 4 disk ...................... 500 work-hours × $85 per hour = $42,500 .... $378,400 $420,900 $1,262,700 

Replace the LPTR stage 6 disk ...................... 500 work-hours × $85 per hour = $42,500 .... 208,900 251,400 251,400 

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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 87, No. 119 / Wednesday, June 22, 2022 / Proposed Rules 37249 

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. 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 adding 

the following new airworthiness 

directive: 

General Electric Company: Docket No. FAA– 

2022–0587; Project Identifier AD–2022– 

00394–E. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by August 8, 

2022. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to General Electric 

Company (GE) GEnx–2B67/P model turbofan 

engines with an installed: 

(1) Low-pressure turbine rotor (LPTR) stage 

4 disk, part number (P/N) 2440M64P01, with

(e) Unsafe Condition 

This AD was prompted by the detection of 

an iron inclusion in a forging, which may 

reduce the fatigue life of certain LPTR stage 

4 disks and LPTR stage 6 disks. The FAA is 

issuing this AD to prevent fracture and 

subsequent uncontainment of the LPTR stage 

4 disk and LPTR stage 6 disk. The unsafe 

condition, if not addressed, could result in 

uncontained debris release, damage to the 

engine, and damage to the airplane. 

(f) Compliance

Airworthiness Directives; The Boeing 

Company Airplanes 

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 The Boeing Company Model 

777–200, 777–200LR, 777–300, 777– 

300ER, and 777F series airplanes. This 

proposed AD was prompted by reports 

of wing anti-ice (WAI) valve failure that 

can result in undetected structural 

damage to leading edge (LE) slat 

assemblies, and separately a failure of 

the autothrottle (A/T) to disconnect after 

advancing the throttle levers, which 

caused a low speed condition during a 

go-around. This proposed AD was also 

prompted by a determination that 

insufficient low-speed protection exists 

in the 777 fleet and a determination that 

the flightcrew may not recognize and 

properly respond to a multi-channel 

unreliable airspeed event. This 

proposed AD would require installing 

certain new software, and doing a 

software configuration check. The FAA 

is proposing this AD to address the 

unsafe conditions on these products. 

DATES: The FAA must receive comments 

on this proposed AD by August 8, 2022. 

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
