Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes.
This AD was prompted by reports of the loss of all air data system
information provided to the flightcrew during flight; the air data
system information was recovered as the airplane descended to lower
altitudes. This AD requires revising the existing airplane flight
manual (AFM) to update the Unreliable Airspeed and Landing Distance
Factor emergency procedures, which provide instructions for the
flightcrew to stabilize the airspeed and altitude. The FAA is issuing
this AD to address the unsafe condition on these products.

DATES: This AD is effective August 11, 2022.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of August 11,
2022.

SUPPLEMENTARY INFORMATION:

Background

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2020-50, dated November 20,
2020 (TCCA AD CF-2020-50) (also referred to after this as the Mandatory
Continuing Airworthiness Information, or 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
https://www.regulations.gov by searching for and locating Docket No.
FAA-2022-0453.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to for certain Bombardier,
Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on April 11, 2022 (87 FR 21047). The NPRM was
prompted by reports of the loss of all air data system information
provided to the flightcrew during flight; the air data system
information was recovered as the airplane descended to lower altitudes.
The NPRM proposed to require revising the existing AFM to update the
Unreliable Airspeed and Landing Distance Factor emergency procedures,
which provide instructions for the flightcrew to stabilize the airspeed
and altitude. The FAA is issuing this AD to address loss of all air
data system information, which could lead to loss of continued safe
flight and landing of the airplane. See the MCAI for additional
background information.

Discussion of Final Airworthiness Directive

Comments

The FAA received no comments on the NPRM or on the determination of
the cost to the public.

Conclusion

The FAA reviewed the relevant data and determined that air safety
requires adopting this AD as proposed. 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. Accordingly,
the FAA is issuing this AD to address the unsafe condition on these
products.

Estimated Costs for Required Actions

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.
