Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of the passenger door failing to dampen during opening at regularly scheduled maintenance checks, causing the door to open more rapidly than normal. An investigation found that a contributing factor was erroneous aircraft maintenance manual (AMM) procedures. This proposed AD would prohibit using certain versions of certain aircraft maintenance manual (AMM) tasks for the passenger door. The FAA is proposing this AD to address the unsafe condition on these products.

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

Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2021-41, dated November 24,
2021 (TCCA AD CF-2021-41) (also referred to after this as the MCAI), to
correct an unsafe condition for certain Bombardier, Inc., Model BD-700-
1A10 and BD-700-1A11 airplanes. You may examine the MCAI in the AD
docket at <a href="http://www.regulations.gov">www.regulations.gov</a> by searching for and locating Docket No.
FAA-2022-0995.
This proposed AD was prompted reports of the passenger door failing
to dampen during opening at regularly scheduled maintenance checks,
causing the door to open more rapidly than normal. An investigation
found that a contributing factor was erroneous AMM procedures. The AMM
tasks related to passenger door maintenance have since been corrected,
and only versions of these tasks dated May 19, 2021, or later have the
correct procedures. The FAA is proposing this AD to prevent rapid
opening of the passenger door, which can result in damage to the door
and consequent injury to maintenance personnel. See the MCAI for
additional background information.
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,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
the unsafe condition
[[Page 49780]]
described previously is likely to exist or develop on other products of
the same type design.
Proposed Requirements of This NPRM
This proposed AD would prohibit using versions issued prior to May
19, 2021 of certain AMM tasks for the passenger door.
Costs of Compliance
The FAA estimates that this proposed AD affects 408 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $34,680
----------------------------------------------------------------------------------------------------------------
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.
