Background 

The TCCA, which is the aviation 

authority for Canada, has issued TCCA 

AD CF–2021–39, dated November 10, 

2021 (TCCA AD CF–2021–39) (also 

referred to as the MCAI), to correct an 

unsafe condition for certain Airbus 

Canada Limited Partnership Models 

BD–500–1A10 and BD–500–1A11 

airplanes. 

This proposed AD was prompted by 

the discovery that overwing emergency 

exit door (OWEED) handle covers were 

difficult to open on some airplanes. An 

investigation revealed that brackets of 

certain OWEED handle covers are prone 

to flexure, thus increasing the force 

necessary to remove the OWEED handle 

cover beyond design requirements. As a 

result, the OWEED handle covers must 

be removed in order to access the 

emergency exit, which could delay 

passenger evacuation. The FAA is 

proposing this AD to address the 

increased force necessary to remove the 

OWEED handle cover to access the 

emergency exit, which could hinder 

passenger evacuation in emergency. See 

the MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

TCCA AD CF–2021–39 specifies 

procedures for replacing the existing 

OWEED handle cover brackets with 

newly designed OWEED handle cover 

brackets and also instructions for 

installing a placard regarding this 

replacement. 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. 

FAA’s Determination 

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, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

is issuing this NPRM after determining 

that the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

TCCA AD CF–2021–39 described 

previously, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate TCCA AD CF–2021–39 by 

reference in the FAA final rule. This 

proposed AD would, therefore require 

compliance with TCCA AD CF–2021–39 

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 

TCCA AD CF–2021–39 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 TCCA AD CF–2021–39. 

Service information required by TCCA 

AD CF–2021–39 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2022–0393 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD would affect 21 airplanes of U.S. 

registry. The FAA estimates the 

following costs to comply with this 

proposed AD: 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 87, No. 66 / Wednesday, April 6, 2022 / Proposed Rules 19817 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

3 work-hours × $85 per hour = $255 .......................................................................................... $40 $295 $6,195 

According to the manufacturer, some 

or all of the costs of this proposed AD 

may be covered under warranty, thereby 

reducing the cost impact on affected 

individuals. The FAA does not control 

warranty coverage for affected 

individuals. As a result, the FAA has 

included all known costs in the cost 

estimate. 

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.

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2018–18–05, which applies to all ATR– 

GIE Avions de Transport Re ́gional 

Model ATR42–200, –300, and –320 

airplanes; and AD 2020–09–16, which 

applies to all ATR–GIE Avions de 

Transport Re ́gional Model ATR42–200, 

–300, and –320 airplanes. AD 2018–18– 

05 and AD 2020–09–16 require revising 

the existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations. Since the FAA issued AD 

2018–18–05 and AD 2020–09–16, the 

FAA has determined that new or more 

restrictive airworthiness limitations are 

necessary. This proposed AD would 

retain the requirements of AD 2020–09– 

16. This proposed AD would also 

require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation 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 May 23, 2022.

Confidential Business Information 

CBI is commercial or financial

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

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 Shahram
