Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed 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 proposed AD would require revising the existing airplane flight manual (AFM) and applicable corresponding operational procedures to incorporate procedures to be applied during erroneous electrical status indication conditions. The FAA is proposing this AD to address the unsafe condition on these products.

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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0691.
This proposed AD was prompted by reports of erratic electrical
system status on the PBA and the EICAS, while on-ground and during
flight. Some of those incidents resulted in the airplane experiencing
momentary loss of electrical power and loss of flight displays
following flightcrew actions. The FAA is proposing 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.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following sections of the applicable
AFMs. This service information provides procedures to inform the pilots
not to turn off active generators in the event of an erroneous
electrical status indication.
<bullet> Section 03-19, Electrical, of Chapter 03, Emergency
Procedures, of the Bombardier Challenger 300 (Imperial Version)
Airplane Flight Manual, Publication No. CSP 100-1, Revision 63, dated
April 1, 2021. (For obtaining this section of the Bombardier Challenger
300 (Imperial Version) Airplane Flight Manual, Publication No. CSP 100-
1, use Document Identification No. CH 300 AFM-I.)
<bullet> Section 05-19, Electrical, of Chapter 05, Non-Normal
Procedures, of

the Bombardier Challenger 300 (Imperial Version) Airplane Flight
Manual, Publication No. CSP 100-1, Revision 63, dated April 1, 2021.
(For obtaining this section of the Bombardier Challenger 300 (Imperial
Version) Airplane Flight Manual, Publication No. CSP 100-1, use
Document Identification No. CH 300 AFM-I.)
<bullet> Section 03-19, Electrical, of Chapter 03, Emergency
Procedures, of the Bombardier Challenger 350 Airplane Flight Manual,
Publication No. CH 350 AFM, Revision 29, dated April 1, 2021.
<bullet> Section 05-19, Electrical, of Chapter 05, Non-Normal
Procedures, of the Bombardier Challenger 350 Airplane Flight Manual,
Publication No. CH 350 AFM, Revision 29, dated April 1, 2021.
These documents are distinct since they apply to different airplane
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 the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
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 AFM and
applicable corresponding operational procedures to incorporate
procedures to be applied during erroneous electrical status indication
conditions.
Explanation of Incorporating Information Specified in an AFM Revision
This proposed AD would require including the information that is
provided in the referenced AFM revisions in paragraph (g) of this
proposed AD. The language in paragraph (g) of this proposed AD is
designed to allow incorporating the specific information, regardless of
the revision level of the AFM in use, provided the language is
identical to the referenced AFM revisions specified in paragraph (g) of
this proposed AD. The language in a later revision of the Bombardier
Challenger 300 (Imperial Version) Airplane Flight Manual, Publication
No. CSP 100-1 that is the same as the language in Bombardier Challenger
300 (Imperial Version) Airplane Flight Manual, Publication No. CSP 100-
1, Revision 63, dated April 1, 2021; or in a later revision of the
Bombardier Challenger 350 Airplane Flight Manual, Publication No. CH
350 AFM that is the same as the language in Bombardier Challenger 350
Airplane Flight Manual, Publication No. CH 350 AFM, Revision 29, dated
April 1, 2021; may be incorporated.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 275 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $23,375
----------------------------------------------------------------------------------------------------------------
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.
