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 a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2022-15, dated April 7, 2022 (Transport
Canada AD CF-2022-15) (also referred to after this as the MCAI), to
correct an unsafe condition on certain Bombardier, Inc., Model BD-700-
1A10, and BD-700-1A11 airplanes. The MCAI states that during a design
review, it was discovered that three candidate certification
maintenance requirements (CCMRs) which were dispositioned as
maintenance review board report (MRBR) tasks had reached or exceeded
the limit for escalation and that exceeding the CCMR limitations could
result in unsafe conditions. The MCAI also states that Bombardier
issued
[[Page 12277]]
certification maintenance requirements (CMRs) to prevent escalation and
reduce the interval, as applicable, for these tasks, which consist of a
functional test of the landing-gear emergency extension; an operational
test of the brake shutoff valve; and a visual check of the passenger-
door vent-flap mechanism.
The FAA is proposing this AD to address the following unsafe
conditions:
<bullet> Dormant failure of the landing gear emergency extension
system, which could lead to failure to extend the landing gear when
normal gear extension has failed. This unsafe condition, if not
addressed, could result in an annunciated failure to extend both main
landing gears or all landing gears.
<bullet> Dormant failure of the brake shut off valve in the open
state. This unsafe condition, if not addressed, could result in
uncommanded braking during take-off.
<bullet> Dormant failure of the vent flap assembly where it fails
in the closed position, which could result in the failure to prevent
the initiation of cabin pressurization when the passenger door is not
fully closed, latched and locked. This unsafe condition, if not
addressed, could result in the passenger door opening under pressure on
ground or during flight.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-0169.

This service information specifies more restrictive airworthiness
limitations for CMRs. These documents are distinct since they apply to
different airplane models in different configurations.
This service information 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 this State of Design Authority,
it has notified the FAA of the unsafe condition described in the MCAI
and service information described above. The FAA is issuing this NPRM
after determining that the unsafe condition described previously is
likely to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require revising the existing maintenance or
inspection program as applicable to incorporate more restrictive
airworthiness limitations.
This proposed AD would require revisions to certain operator
maintenance documents to include new actions (e.g., inspections).
Compliance with these actions is required by 14 CFR 91.403(c). For
airplanes that have been previously modified, altered, or repaired in
the areas addressed by this proposed AD, the operator may not be able
to accomplish the actions described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must request
approval for an alternative method of compliance according to paragraph
(i)(1) of this proposed AD.
Differences Between This NPRM and the MCAI
Where Transport Canada AD CF-2022-15 references associated MRBRs
tasks, Figure 1 to paragraph (g) of this proposed AD references AMM
tasks instead. The FAA has determined that CCMRs cannot be mandated by
the FAA. However, equivalent AMM tasks may be mandated in lieu of
CCMRs.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 413 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
The FAA has determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although the
agency recognizes that this number may vary from operator to operator.
Since operators incorporate maintenance or inspection program changes
for their affected fleet(s), the FAA has determined that a per-operator
estimate is more accurate than a per-airplane estimate. Therefore, the
agency estimates the average total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).
[[Page 12278]]
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.

to address the unsafe conditions identified in paragraphs (e)(1)
through (3) of this AD.
(1) Dormant failure of the landing gear emergency extension
system, which could lead to failure to extend the landing gear when
normal gear extension has failed. This unsafe condition, if not
addressed, could result in an annunciated failure to extend both
main landing gears or all landing gears.
(2) Dormant failure of the brake shut off valve in the open
state. This unsafe condition, if not addressed, could result in
uncommanded braking during take-off.
(3) Dormant failure of the vent flap assembly where it fails in
the closed position, which could result in the failure to prevent
the initiation of cabin pressurization when the passenger door is
not fully closed, latched and locked. This unsafe condition, if not
addressed, could result in the passenger door opening under pressure
on ground or during flight.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Maintenance or Inspection Program Revision
Within 30 days from the effective date of this AD, revise the

maintenance requirements (CMR) tasks identified in Figure 1 to
paragraph (g) of this AD of Part 2, ``Airworthiness Limitations,''
of the applicable Time Limits/Maintenance Checks (TLMC) manuals
identified in Figure 2 to paragraph (g) of this AD. The initial
compliance time for doing the tasks is at the applicable time
specified in Figure 1 to paragraph (g) of this AD, or within 30 days
after the effective date of this AD, whichever occurs later.
