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 all 

The Boeing Company Model MD–11 

and MD–11F airplanes. This proposed 

AD was prompted by reports indicating 

incidents of wires chafing against the 

inboard upper corner of the observer 

station circuit breaker panel. This 

proposed AD would require, depending 

on airplane configuration, doing a 

general visual inspection of the right 

observer station upper main circuit 

breaker panel and wiring for certain 

missing parts; doing an inspection of the 

right observer station upper main circuit 

breaker panel to determine if a certain 

bracket part number is installed; doing 

a general visual inspection of certain 

wire assemblies for any damage; 

modifying the observer station upper 

main circuit breaker panel; and 

applicable on-condition actions. 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 October 4, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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 Eric Igama, Aerospace 

Engineer, Systems and Equipment 

Section, FAA, Los Angeles ACO Branch,

CBI will be placed in the public docket 

for this rulemaking. 

Background 

The FAA has received reports 

indicating incidents of wires chafing 

against the inboard upper corner of the 

observer station circuit breaker panel. It 

has been determined that this condition 

allows for the chafed electrical wires to 

arc against the metal panel during the 

opening and closing of the panel. This 

condition, if not addressed, could result 

in wire chafing and arcing on the panel, 


jbell on DSKJLSW7X2PROD with PROPOSALS
46168 Federal Register / Vol. 86, No. 157 / Wednesday, August 18, 2021 / Proposed Rules 

which could cause damage to 

equipment, and result in loss of 

electrical power and a possible in-flight 

fire. 

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 Boeing Alert 

Service Bulletin MD11–24A204, 

Revision 2, dated April 14, 2021. For 

certain airplanes, this service 

information describes procedures for 

doing a general visual inspection of the 

right observer station upper main circuit 

breaker panel and wiring for missing 

installation of sleeving, grommets, and 

spacers; doing an inspection of the right 

observer station upper main circuit 

breaker panel to determine if bracket 

part number SR11240046–11 is 

installed; and applicable on-condition 

actions. On-condition actions include 

repairing or replacing damaged wires, 

installing sleeves and routing wires, 

trimming and re-identifying the bracket, 

and replacing any missing grommets or 

spacers. 

For certain other airplanes, this 

service information describes 

procedures for doing a general visual 

inspection of wire assemblies ABS9110 

and ABS9115 for any damage (i.e., wire 

chafing, arcing), modifying the observer 

station upper main circuit breaker 

panel, and applicable on-condition 

actions. On-condition actions include 

repairing or replacing damaged wires. 

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 

accomplishing the actions identified as 

‘‘RC’’ (required for compliance) in the 

Accomplishment Instructions of Boeing 

Alert Service Bulletin MD11–24A204, 

Revision 2, dated April 14, 2021, 

already described, except for any 

differences identified as exceptions in 

the regulatory text of this proposed AD. 

For information on the procedures and 

compliance times, see this service 

information at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0564. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 118 

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 

Inspections ................ Up to 17 work-hours × $85 per hour = Up to $1,445 ... $0 Up to $1,445 ............. Up to $170,510. 

The FAA estimates the following 

costs to do any necessary actions that 

would be required based on the results 

of the proposed inspection. The FAA 

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 

Replacement, installation and trimming ...................... Up to 3 work-hours × $85 per hour = Up to $255 ..... $428 Up to $683. 

* The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs specified in this proposed AD. 

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: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows:

issuing this AD to address wire chafing and 

arcing on the panel, which could cause 

damage to equipment, and result in loss of 

electrical power and a possible in-flight fire. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Except as specified in paragraph (h) of this

Alert Service Bulletin MD11–24A204, 

Revision 2, dated April 14, 2021, do all 

applicable actions identified as ‘‘RC’’ 

(required for compliance) in, and in 

accordance with, the Accomplishment 

Instructions of Boeing Alert Service Bulletin 

MD11–24A204, Revision 2, dated April 14, 

2021. 

(h) Exception to Service Information 

Specifications 

Where Boeing Alert Service Bulletin 

MD11–24A204, Revision 2, dated April 14, 

2021, uses the phrase ‘‘the Revision 2 date of 

this service bulletin,’’ this AD requires using 

‘‘the effective date of this AD.’’ 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Los Angeles ACO Branch, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. In accordance with 

14 CFR 39.19, send your request to your 

principal inspector or responsible Flight 

Standards Office, as appropriate. If sending 

information directly to the manager of the 

certification office, send it to the attention of 

the person identified in Related Information. 

Information may be emailed to: 9-ANMLAACO-AMOC-Requests@faa.gov. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the responsible Flight Standards Office. 

(3) An AMOC that provides an acceptable 

level of safety may be used for any repair, 

modification, or alteration required by this 

AD if it is approved by The Boeing Company 

Organization Designation Authorization 

(ODA) that has been authorized by the 

Manager, Los Angeles ACO Branch, FAA, to 

make those findings. To be approved, the 

repair method, modification deviation, or 

alteration deviation must meet the 

certification basis of the airplane, and the 

approval must specifically refer to this AD. 

(4) For service information that contains 

steps that are labeled as Required for 

Compliance (RC), the provisions of 

paragraphs (i)(4)(i) and (ii) of this AD apply. 

(i) The steps labeled as RC, including 

substeps under an RC step and any figures 

identified in an RC step, must be done to 

comply with the AD. If a step or substep is 

labeled ‘‘RC Exempt,’’ then the RC 

requirement is removed from that step or 

substep. An AMOC is required for any 

deviations to RC steps, including substeps 

and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps, 

including substeps and identified figures, can 

still be done as specified, and the airplane 

can be put back in an airworthy condition.

ENVIRONMENTAL PROTECTION 

AGENCY 

40 CFR Part 52 

[EPA–R10–OAR–2019–0574, FRL–8814–01– 

R10] 

Approval and Promulgation of Air 

Quality Implementation Plans; 

Washington; Low Emission Vehicle 

Program 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to approve a 

revision to the Washington State 

Implementation Plan (SIP) pertaining to 

adoption by reference of a Low 

Emission Vehicle (LEV) program by the 

State of Washington. The Clean Air Act 

(CAA) grants authority to the EPA to 

adopt federal standards relating to the 

control of emissions from new motor 

vehicles, and generally preempts states 

from doing so. However, the CAA 

provides California the ability to adopt 

and enforce its own new motor vehicle 

emission standards, as long as the EPA 

approves California’s standards via a 

preemption waiver. The CAA also 

allows other states to adopt California’s 

new motor vehicle emission standards 

for which the EPA has granted such a 

waiver providing other relevant criteria 

are met. Washington adopted 

California’s LEV emission standards in 

2005, effective with new vehicles sold 

in model year 2009. Washington 

subsequently amended its new motor 

vehicle emissions program to 

incorporate California’s LEV updates to 

its program. The purpose of this SIP 

revision is to implement programs to 

reduce vehicle emissions that contribute 

to formation of ground level ozone and 

fine particulate matter. Washington did 

not submit provisions related to 

greenhouse gas emissions from new 

motor vehicles or zero-emission 

vehicles requirements for inclusion in 

the SIP. The EPA is proposing to 

approve Washington’s LEV SIP revision, 

as it relates to criteria pollutants, in 

accordance with the requirements of the 

CAA.
