[Docket No. FAA-2022-1646; Project Identifier MCAI-2022-01135-T;
Amendment 39-22348; AD 2023-04-01]
Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
SUMMARY: The FAA is adopting a new airworthiness directive (AD)
certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was
prompted by report that the passenger door functional test engineering
requirements (FTERs) were not fully accomplished on several airplanes.
This AD requires measuring the passenger door steps, passenger door
gaps, and passenger door stops rigging, and re-adjusting the door if
necessary. The FAA is issuing this AD to address the unsafe condition
on these products.
DATES: This AD is effective April 7, 2023.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 7,
AD Docket: You may examine the AD docket at regulations.gov under
Docket No. FAA-2022-1646; or in person at Docket Operations between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains this final rule, the mandatory continuing airworthiness
information (MCAI), any comments received, and other information. The

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Bombardier,
Inc., Model BD-700-2A12 airplanes. The NPRM published in the Federal
Register on December 16, 2022 (87 FR 77040). The NPRM was prompted by
AD CF-2022-48, dated August 18, 2022, issued by Transport Canada, which
is the aviation authority for Canada (Transport Canada AD CF-2022-48)
(also referred to as the MCAI). The MCAI states that non-conformities
have been reported involving the passenger door FTERs. It has been
found that the FTER was not fully accomplished on several airplanes
with the assembled airplane in the weight-on-wheel condition, which
could affect the rigging of the passenger door. Door mis-rigging could
result in higher loads on the passenger door stops that could initiate
cracks before the intended design service goal, and an in-flight
opening of the passenger door
In the NPRM, the FAA proposed to require measuring the passenger
door steps, passenger door gaps, and passenger door stops rigging, and
re-adjusting the door if necessary. The FAA is issuing this AD to
address the unsafe condition on these products.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2022-1646.
Discussion of Final Airworthiness Directive
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
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 this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
referenced above. The FAA reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD to address the unsafe condition on this product.
Except for minor editorial changes, this AD is adopted as proposed in
the NPRM. None of the changes will increase the economic burden on any
Related Service Information Under 1 CFR Part 51
The FAA reviewed Bombardier Service Bulletin 700-52-7511, dated
July 22, 2022. This service information specifies procedures for
measuring the passenger door steps and gaps, rigging of the passenger
door stops, and corrective actions if the measurements are not within
the specified limits. 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.
Costs of Compliance
The FAA estimates that this AD affects 29 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
|Up to 4 work-hours x $85 per
hour = $340
Up to $9,860
The FAA estimates the following costs
to do any necessary on-
condition actions 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 these on-condition actions:
Estimated Costs of On-Condition Actions
|Up to 30 work-hours x $85 per
hour = $3,400
Up to $3,400
The FAA has included all known costs
in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected operators.
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.
This AD will not have federalism implications under Executive Order
13132. This AD will 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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
