SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued an NPRM that 

proposed to amend 14 CFR part 39 by 

adding an AD for all Airbus SAS Model 

A319–111, –112, –113, –114, –115, 

–131, –132, and –133 airplanes; Model

A320–211, –212, –214, –216, –231,

–232, and –233 airplanes; and Model

A321–111, –112, –131, –211, –212,

–213, –231, –232, and –271N airplanes.

The NPRM was published in the

Federal Register on May 24, 2024 (89

FR 45800). The NPRM was prompted by

a determination that a damage-tolerance

and fatigue reassessment of NLG repairs

is necessary for certain parts fitted on

airplanes approved for operation in the

CIS. The NPRM proposed to require

repair and replacement of all affected

parts, and to limit the installation of

affected parts, as specified in an EASA

AD.

The proposed actions were intended 

to address NLG repairs for certain parts 

fitted on airplanes approved for 

operation in the CIS, and to prevent 

damage or failure of the affected parts 

and the NLG, and possible damage to 

the airplane and injury to occupants. 

Actions Since the NPRM Was Issued 

Since issuance of the NPRM, the FAA 

has learned of errors in the 

applicability. Paragraph (c)(3) of the 

NPRM included some airplanes that 

were not intended to be included, and 

it omitted airplanes that should have 

been included. In light of this error, the 

FAA is issuing further rulemaking 

(Docket No. FAA–2024–2314) to correct 

the applicability. 

Withdrawal of the NPRM constitutes 

only such action and does not preclude 

the FAA from further rulemaking on 

this issue, nor does it commit the FAA 

to any course of action in the future. 

Comments 

The Air Line Pilots Association, 

International (ALPA) supported the 

NPRM. American Airlines advised the 

FAA of errors in the applicability 

specified in the NPRM. 

Explanation of Applicability Errors 

The following errors were included in 

the NPRM: 

• Paragraph (c)(1) of the proposed AD

incorrectly omitted Model A319–151N 

and –153N airplanes. 

• Paragraph (c)(2) of the proposed AD

incorrectly omitted Model A320–251N, 

–252N, –253N, –271N, –272N, and

–273N airplanes.

• Paragraph (c)(3) of the proposed AD

incorrectly included A321–111, –112, 

and –131 airplanes, and omitted Model 

A321–211, –212, –213, –231, –232, 

–251N, –251NX, –252N, –252NX,

–253N, –253NX, –271N, –271NX,

–272N, and –272NX airplanes.

FAA’s Conclusions

Upon further consideration, the FAA 

has determined that the NPRM does not 

adequately address the identified unsafe 

condition. Accordingly, the NPRM is 

withdrawn. 

Regulatory Findings 

Since this action only withdraws an 

NPRM, it is neither a proposed nor a 

final rule. This action therefore is not 

covered under Executive Order 12866, 

the Regulatory Flexibility Act, or DOT 

Regulatory Policies and Procedures (44 

FR 11034, February 26, 1979).

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2022–15–06, which applies to all The 

Boeing Company Model 777–200, 

–200LR, –300, –300ER, and 777F series

airplanes. AD 2022–15–06 requires

disconnecting certain connectors and

capping and stowing the wires that had

been attached to the affected transorb

modules. Since the FAA issued AD

2022–15–06, the agency has determined

additional connectors are affected. Also,

a replacement has been developed to

address the unsafe condition, which

would terminate the existing actions.

This proposed AD would continue to

require the actions specified in AD

2022–15–06 and would require those

actions for additional connectors. This

proposed AD would also require

determining if affected transorb

modules are installed, replacing or

testing affected transorb modules, and

applicable on-condition actions. This

proposed AD would also prohibit the

installation of affected parts. 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 12,

2024.

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

rulemaking. 

Background 

The FAA issued AD 2022–15–06, 

Amendment 39–22126 (87 FR 47334, 

August 3, 2022) (AD 2022–15–06), for 

all The Boeing Company Model 777– 

200, –200LR, –300, –300ER, and 777F 

series airplanes. AD 2022–15–06 was 

prompted by high electrical resistance 

within the gust suppression sensor 

(GSS) transorb modules due to corrosion 

on the transorb threads. AD 2022–15–06 

requires disconnecting certain 

connectors and capping and stowing the 

wires that had been attached to the 

affected transorb modules. The FAA 

issued AD 2022–15–06 to address high 

electrical resistance in both transorb 

modules, which can result in two 

actuator control electronics (ACEs) 

being exposed to damaging lightning 

transient voltages in excess of the 

qualification levels, potentially 

inducing erroneous or oscillatory 

outputs to flight control surfaces. The 

unsafe condition, if not addressed, 

could result in loss of control of the 

airplane. 

Actions Since AD 2022–15–06 Was 

Issued 

Since the FAA issued AD 2022–15– 

06, a replacement mitigating action has 

been developed to address the unsafe 

condition, which would terminate the 

existing actions. The preamble to AD 

2022–15–06 explains that the FAA 

considers the requirements ‘‘interim 

action’’ and may consider further 

rulemaking. The FAA has now 

determined that further rulemaking is 

indeed necessary, and the replacement 

specified in this proposed AD follows 

from that determination. 

In addition, Boeing and several 

operators notified the FAA that certain 

bundles/connectors were not identified 

in AD 2022–15–06. Boeing noted that 

there are connector designation 

variances between earlier and later 

Model 777 airplanes and that bundle/ 

connector W7314/D02099P is on the 

right-hand side of certain line number 

airplanes. Boeing stated it sent a Boeing 

multi-operator message to operators to 

reduce confusion and recommended 

bundle/connector W7314/D02099P be 

identified as an affected bundle/ 

connector. American Airlines, Qatar 

Airways, and United Airlines also noted 

that bundle/connector W7314/D02099P 

is not identified in AD 2022–15–06. 

United Airlines, All Nippon Airways, 

and Kilitta Air, LLC, noted that bundle/ 

connector W6313/D02098P is not 

identified in AD 2022–15–06 but it is 

identified as a bundle/connector for 

certain airplanes. 

The FAA has determined the 

additional connectors are affected by the 

unsafe condition. Therefore, this 

proposed AD would require that 

operators disconnect the connectors and 

cap and stow the wires to bundles/ 

connectors W6313/D02098P and 

W7314/D02099P until the proposed 

replacement is done as specified in 

paragraph (h) of this proposed AD. 

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. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 777–27A0125 

RB, dated February 3, 2023. This 

material specifies procedures for 

replacing affected transorb modules 

with new or serviceable transorb 

modules or testing affected transorb 

modules and accomplishing applicable 

on-condition actions. The on-condition 

actions include part marking any 

module that meets certain specifications 

or replacing any modules that do not 

meet the specifications. 

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 the ADDRESSES section.

Federal Register / Vol. 89, No. 187 / Thursday, September 26, 2024 / Proposed Rules 78829 

Proposed AD Requirements in This 

NPRM 

This proposed AD would retain all 

requirements of AD 2022–15–06 and 

would require those actions for 

additional connectors. This proposed 

AD would also require determining if 

affected transorb modules are installed, 

replacing or testing affected transorb 

modules, and applicable on-condition 

actions. This proposed AD would also 

prohibit the installation of affected 

parts. 

For information on the procedures 

and compliance times, see Boeing Alert 

Requirements Bulletin 777–27A0125 

RB, dated February 3, 2023, at 

regulations.gov under Docket No. FAA– 

2024–2144. 

Differences Between This Proposed AD 

and the Referenced Material 

The effectivity of Boeing Alert 

Requirements Bulletin 777–27A0125 

RB, dated February 3, 2023, is limited 

to Model 777–200, –200LR, –300, 

–300ER, and 777F series airplanes, 

having certain line numbers. However, 

the applicability of this proposed AD 

includes all Model 777–200, –200LR, 

–300, –300ER, and 777F series 

airplanes. Because the affected parts are 

rotable parts, the FAA has determined 

that these parts could later be installed 

on airplanes that were initially 

delivered with acceptable parts, thereby 

subjecting those airplanes to the unsafe 

condition. The FAA has confirmed with 

Boeing that the Accomplishment 

Instructions in Boeing Alert 

Requirements Bulletin 777–27A0125 

RB, dated February 3, 2023, are 

applicable to the expanded group of 

airplanes. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 312 

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 

Disconnecting connectors, capping and 

stowing wires (retained actions from 

AD 2022–15–06).

3 work-hours × $85 per hour = $255 ....... $0 ..................... $255 ................. $79,560. 

Disconnecting additional connectors, capping and stowing wires (new proposed 

action).

3 work-hours × $85 per hour = $255 ....... $0 ..................... $255 ................. $79,560. 

Determining if affected transorb modules 

are installed, and replacing or testing 

affected modules (new proposed action).

Up to 3 work-hours × $85 per hour = 

$255.

Up to $3,668 .... Up to $3,923 ..... Up to $1,223,976. 

The FAA estimates the following 

costs to do any necessary on-condition 

actions that would be required based on 

the results of the proposed testing. The 

agency has no way of determining the 

number of aircraft that might need these 

actions: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Part marking or replacing affected modules .............. Up to 3 work-hours × $85 per hour = $255 .............. Up to $3,668 .... Up to $3,923. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

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, 

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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority, as it would 

establish Class E airspace extending 

upward from 700 feet above the surface 

at Transylvania Community Hospital, 

Brevard, NC, to support standard 

instrument approach procedures for IFR 

operations at this heliport.

proposal, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should submit only one 

time if comments are filed 

electronically, or commenters should 

send only one copy of written 

comments if comments are filed in 

writing. 

The FAA will file in the docket all 

comments it receives, as well as a report 

summarizing each substantive public 

contact with FAA personnel concerning 

this proposed rulemaking. Before acting 

on this proposal, the FAA will consider 

all comments it receives on or before the 

closing date for comments. The FAA 

will consider comments filed after the 

comment period has closed if it is 

possible to do so without incurring 

expense or delay. The FAA may change 

this proposal in light of the comments 

it receives. 

Privacy: In accordance with 5 U.S.C. 

553(c), DOT solicits comments from the 

public to better inform its rulemaking 

process. DOT posts these comments, 

without edit, including any personal 

information the commenter provides, to
