SUPPLEMENTARY INFORMATION:
Background
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-700-1A10 and -1A11 airplanes. The NPRM published in the
Federal Register on February 27, 2023 (88 FR 12276). The NPRM was
prompted by AD CF-2022-15, dated April 7, 2022, issued by Transport
Canada, which is the aviation authority for Canada (referred to after
this as the MCAI). 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 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.
In the NPRM, the FAA proposed to require revising the existing
maintenance or inspection program as applicable to incorporate more
restrictive airworthiness limitations. The FAA is issuing 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 takeoff.
<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.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from an individual who supported the NPRM
without change.
The FAA received additional comments from NetJets. The following
presents the comments received on the NPRM and the FAA's response to
each comment.
Request for Clarification on Repetitive Intervals
NetJets requested that the FAA clarify the repetitive intervals for
the CMR tasks after initial accomplishment. NetJets pointed to the
language in paragraph B of Transport Canada AD CF-2022-15, which states
that after doing the initial actions at the time specified in Table 1
of Transport Canada AD CF-2022-15 (similar to Figure 1 to paragraph (g)
of this AD), accomplishing the CMR tasks are to be done at the
intervals specified in the applicable TLMC manual identified in Table 2
of the Transport Canada AD CF-2022-15 (similar to Figure 2 to paragraph
(g) of this AD).
The FAA agrees that the repetitive interval is not specified in
this AD; however, operators can find this information in the
corresponding TLMC as identified in Figure 2 to paragraph (g) of this
AD. Although Transport Canada AD CF-2022-15 requires both revising the
maintenance program to include limitations, and doing certain
repetitive actions and/or maintaining CDCCLs, this AD only requires the
revision of the maintenance program. Requiring a revision of the
maintenance program rather than requiring individual repetitive actions
or maintaining CDCCLs requires operators to record AD compliance only
at the time the revision to the program is made. Repetitive actions or
maintaining the CDCCLs specified in the airworthiness limitations must
be complied with in accordance with 14 CFR 91.403(c). This AD has not
been changed in this regard.
Request To Clarify Initial Compliance Time for Certain Airplanes
NetJets requested clarification on initial compliance times for
airplanes having more than 1,550 flight hours but have not previously
accomplished the specific CMR or associated airplane maintenance manual
(AMM) task.
The FAA agrees to clarify. For an airplane that has more than 1,550
flight hours, but has not previously accomplished an associated task,
the initial compliance time is within 30 days after the effective date
of this AD. Paragraph (g) of this AD specifies the initial compliance
time is within 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. For example, for task 32-34-00-101, an airplane
that has more than 1,550 flight hours is beyond the initial compliance
time specified in Figure 1 to paragraph (g) of the AD, so the ``within
30 days after the effective date of this AD'' would come later. This AD
has not been changed in this regard.
Conclusion
This product has been approved by the aviation authority of another
[[Page 42595]]
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, considered the
comments received, 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 operator.

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.
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 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).
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
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
Order 12866,
(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.
