Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model 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. This proposed AD would require replacing the existing OWEED handle cover brackets with newly designed OWEED handle cover brackets and the installation of a placard regarding this replacement, as specified in Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> 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:
[[Page 19817]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $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.

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
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Airbus Canada Limited Partnership (Type Certificate Previously Held
by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.):
Docket No. FAA-2022-0393; Project Identifier MCAI-2021-01249-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by May 23, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Airbus Canada Limited Partnership (Type
Certificate Previously Held by C Series Aircraft Limited Partnership
(CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11
airplanes, certificated in any category, as identified in Transport
Canada Civil Aviation (TCCA) AD CF-2021-39, dated November 10, 2021

(e) Unsafe Condition
This AD was prompted by 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. 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 an emergency.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, TCCA AD CF-2021-39.
(h) Exception to TCCA AD CF-2021-39
Where TCCA AD CF-2021-39 refers to its effective date, this AD
requires using the effective date of this AD.
(i) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York ACO Branch, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. In
