Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0227, dated October 19, 2020 

(EASA AD 2020–0227) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain ATR–GIE Avions de 

Transport Re ́gional Model ATR72–212A 

airplanes. 

This proposed AD was prompted by 

a report of an engine electrical control 

#1 fault during flight caused by damage 

on an electrical harness bundle. It was 

determined that this event was due to 

the bundle chafing with an air duct 

clamp located behind the overhead bins 

in fuselage zone 253. Investigation 

revealed that the chafing damage was 

due to insufficient length between the 

air duct clamp and the harness bundle, 

leading to tension in the wire sheath. 

The FAA is proposing this AD to 

address such damage, which could 

result in wire failure and a short circuit, 

an uncontrolled fire, and consequent 

loss of multiple systems, possibly 

resulting in reduced controllability of 

the airplane. See the MCAI for 

additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0227 describes 

procedures for modifying the 

installation of the electrical harness 

routes 1M and 1S–1V, and rotating the 

de-icing pipe coupling installation. 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.

10492 Federal Register / Vol. 86, No. 33 / Monday, February 22, 2021 / Proposed Rules 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is proposing this AD 

because the FAA 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 require 

accomplishing the actions specified in 

EASA AD 2020–0227 described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA initially worked with 

Airbus and EASA to develop a process 

to use certain EASA ADs as the primary 

source of information for compliance 

with requirements for corresponding 

FAA ADs. The FAA has since 

coordinated with other manufacturers 

and civil aviation authorities (CAAs) to 

use this process. As a result, EASA AD 

2020–0227 will be incorporated by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2020–0227 

in its entirety, through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

the EASA AD does not mean that 

operators need comply only with that 

section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in the EASA AD. Service 

information specified in EASA AD 

2020–0227 that is required for 

compliance with EASA AD 2020–0227 

will be available on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2020–1184 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 3 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

1 work-hour × $85 per hour = $85 .............................................................................................. $20 $105 $315 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2020–09–14, which applies to certain 

Airbus SAS Model A350–941 and –1041 

airplanes. AD 2020–09–14 requires 

revising the existing airplane flight 

manual (AFM) to define a liquidprohibited zone on the flight deck and 

provide procedures following liquid 

spillage on the center pedestal. AD 

2020–09–14 also requires installing a 

removable integrated control panel (ICP) 

cover on the flight deck and further 

revising the AFM to include 

instructions for ICP cover use. Since the 

FAA issued AD 2020–09–14, a new, 

water-resistant ICP has been developed. 

This proposed AD would require 

installing a new, water-resistant ICP, 

which would allow removing the ICP 

protective cover and the AFM revisions, 

as specified in a European Union 

Aviation Safety Agency (EASA) AD, 

which will be incorporated by reference. 

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 April 8, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
