ACTION: Final rule.
AGENCY:
The FAA is adopting a new
airworthiness directive (AD) for certain
Bombardier, Inc., Model BD–100–1A10
airplanes. This AD was prompted by
reports of erratic electrical system status
on the push button annunciators (PBAs)
and the engine instrument and crew
alerting system (EICAS). This AD
requires revising the existing airplane
flight manual (AFM) to incorporate
procedures to be applied during
erroneous electrical status indication
conditions. The FAA is issuing this AD
to address the unsafe condition on these
products.
DATES: This AD is effective January 10,
2022.

SUPPLEMENTARY INFORMATION:
Background
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued TCCA AD CF–
2020–46, dated November 17, 2020
(TCCA AD CF–2020–46) (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–100–1A10 airplanes. You
may examine the MCAI in the AD
docket at https://www.regulations.gov
by searching for and locating Docket No.
FAA–2021–0691.
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–100–1A10 airplanes. The NPRM
published in the Federal Register on
August 23, 2021 (86 FR 47036). The
NPRM was prompted by reports of
erratic electrical system status on the
PBAs and the EICAS. The NPRM
proposed to require revising the existing
AFM to incorporate procedures to be
applied during erroneous electrical
status indication conditions. The FAA is
issuing this AD to address erroneous
indications that could mislead pilots,
causing them to turn off active electrical
power sources, leading to partial or
complete loss of electrical power. Loss
of electrical power could result in the
loss of flight displays and reduced
controllability of the airplane. See the
MCAI for additional background
information.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. 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 and the
public interest require adopting this
final rule as proposed, except for minor
editorial changes. The FAA has
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

CFR Part 51

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.

authority for Canada, has issued TCCA AD CF-2020-46, dated November 17,
2020 (TCCA AD CF-2020-46) (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-100-1A10
airplanes. You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0691.
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-100-1A10 airplanes. The NPRM published in the Federal
Register on August 23, 2021 (86 FR 47036). The NPRM was prompted by
reports of erratic electrical system status on the PBAs and the EICAS.
The NPRM proposed to require revising the existing AFM to incorporate
procedures to be applied during erroneous electrical status indication
conditions. The FAA is issuing this AD to address erroneous indications
that could mislead pilots, causing them to turn off active electrical
power sources, leading to partial or complete loss of electrical power.
Loss of electrical power could result in the loss of flight displays
and reduced controllability of the airplane. See the MCAI for
additional background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. 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
and the public interest require adopting this final rule as proposed,
except for minor editorial changes. The FAA has determined that these
minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

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.
