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 a report indicating that during production, the manual opening and closing of the over-wing emergency exit door (OWEED) prior to the installation of the OWEED interior panel could have resulted in damaged insulation blankets below the left and right OWEEDs. This proposed AD would require a one-time inspection for damage of the insulation blankets below the left and right OWEEDs, and replacement if necessary, as specified in a 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.

SUMMARY: 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 a report
indicating that during production, the manual opening and closing of
the over-wing emergency exit door (OWEED) prior to the installation of
the OWEED interior panel could have resulted in damaged insulation
blankets below the left and right OWEEDs. This proposed AD would
require a one-time inspection for damage of the insulation blankets
below the left and right OWEEDs, and replacement if necessary, as
specified in a 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
TCCA, which is the aviation authority for Canada, issued TCCA AD
CF-2021-03 on February 11, 2021 (TCCA AD CF-2021-03) (also referred to
as the Mandatory Continuing Airworthiness Information, or the MCAI), to
correct an unsafe condition for certain Airbus Canada Limited
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes.
This proposed AD was prompted by a report indicating that during
production, the manual opening and closing of the OWEED prior to the
installation of the OWEED interior panel could have resulted in damaged
insulation blankets below the left and right OWEEDs. The insulation
blanket acts as a fire penetration barrier. The FAA is proposing this
AD to address potential damage to the insulation blankets, which could
result in delayed passenger evacuation in the event of post-crash/post-
impact fire events outside the airplane. See the MCAI for additional
background information.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2021-03 describes procedures for a one-time visual
inspection for damage of the insulation blankets below the left and
right OWEEDs, and replacement of any damaged insulation blankets. 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 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 TCCA AD CF-2021-03 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 developed a process to use certain 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,
TCCA AD CF-2021-03 will be incorporated by reference in the FAA final
rule. This proposed AD would, therefore, require compliance with TCCA
AD CF-2021-03 in its entirety, through that incorporation, except for
any differences identified as exceptions in the regulatory text of this
proposed AD. Service information specified in TCCA AD CF-2021-03 that
is required for compliance with it will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0615 after the FAA final rule is published.
Costs of Compliance
The FAA estimates that this proposed AD affects 33 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
[[Page 41790]]
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........................... $0 $255 $8,415
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:
Estimated Costs of On-Condition Action
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170.... $150 $320
------------------------------------------------------------------------
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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
