The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2021–1014; Project Identifier MCAI–2021–00428–T] RIN 2120–AA64 Airworthiness Directives; Bombardier, Inc., Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model BD–100–1A10 airplanes. This proposed AD was prompted by a report that the design of the spoiler control system causes certain engine indication and crew alerting system (EICAS) messages to be posted intermittently and repetitively during flight and on the ground, and flightcrews must action the appropriate checklist each time these messages appear. This proposed AD would require revising the Non-Normal Procedures section of the existing airplane flight manual (AFM) associated with the spoiler electronic control unit (SECU) EICAS messages. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by January 10, 2022.

Background Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF– 2021–14, dated April 7, 2021 (also referred to after this as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all 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–2021–1014. This proposed AD was prompted by a report that the design of the spoiler control system causes certain EICAS messages to be posted intermittently and repetitively during flight and on the ground, and flightcrews must action the appropriate checklist each time these messages appear. The FAA is proposing this AD to address intermittent and E:\FR\FM\26NOP1.SGM 26NOP1 Federal Register / Vol. 86, No. 225 / Friday, November 26, 2021 / Proposed Rules repetitive messaging, which increases overall workload and introduces a risk that flightcrews could become desensitized over time to the messages. This could result in the required checklist not being carried out or completed, and could adversely affect the airplane’s continued safe flight and landing. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following AFM procedures, which include a Caution and a Note to the SPOILERS FAULT (C) Non-Normal Procedures, to reinforce the importance of completing the procedure in its entirety each time the message appears. • Section 05–23, Flight Controls, of Chapter 05, Non-Normal Procedures, of the Bombardier Challenger 300 (Imperial Version) Airplane Flight Manual, Publication No. CSP 100–1, Revision 61, dated September 25, 2020. (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.) • Section 05–23, Flight Controls, of Chapter 05, Non-Normal Procedures, of the Bombardier Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, Revision 27, dated September 25, 2020. 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 67363 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 AFMs already described. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 654 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $55,590 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. jspears on DSK121TN23PROD with PROPOSALS1 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 VerDate Sep<11>2014 16:58 Nov 24, 2021 Jkt 256001 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.

Background

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2021-14, dated April 7, 
2021 (also referred to after this as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all 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-2021-1014.
    This proposed AD was prompted by a report that the design of the 
spoiler control system causes certain EICAS messages to be posted 
intermittently and repetitively during flight and on the ground, and 
flightcrews must action the appropriate checklist each time these 
messages appear. The FAA is proposing this AD to address intermittent 
and

[[Page 67363]]

repetitive messaging, which increases overall workload and introduces a 
risk that flightcrews could become desensitized over time to the 
messages. This could result in the required checklist not being carried 
out or completed, and could adversely affect the airplane's continued 
safe flight and landing. See the MCAI for additional background 
information.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following AFM procedures, which include a 
Caution and a Note to the SPOILERS FAULT (C) Non-Normal Procedures, to 
reinforce the importance of completing the procedure in its entirety 
each time the message appears.
     Section 05-23, Flight Controls, of Chapter 05, Non-Normal 
Procedures, of the Bombardier Challenger 300 (Imperial Version) 
Airplane Flight Manual, Publication No. CSP 100-1, Revision 61, dated 
September 25, 2020. (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.)
     Section 05-23, Flight Controls, of Chapter 05, Non-Normal 
Procedures, of the Bombardier Challenger 350 Airplane Flight Manual, 
Publication No. CH 350 AFM, Revision 27, dated September 25, 2020.
    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 AFMs already described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 654 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

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.

List of Subjects in 14 CFR Part 39

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Bombardier, Inc.: Docket No. FAA-2021-1014; Project Identifier MCAI-
2021-00428-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by January 10, 2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Bombardier, Inc., Model BD-100-1A10 
airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
controls.

(e) Unsafe Condition

    This AD was prompted by a report that the design of the spoiler 
control system causes certain engine indication and crew alerting 
system (EICAS) messages to be posted intermittently and repetitively 
during flight and on the ground, and flightcrews must action the 
appropriate checklist each time these messages appear. The FAA is 
issuing this AD to address intermittent and repetitive messaging, 
which increases overall workload and introduces a risk that 
flightcrews could become desensitized over time to the messages. 
This could result in the required checklist not being carried out or 
completed, and could adversely affect the airplane's continued safe 
flight and landing.

[[Page 67364]]

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Revision of the Airplane Flight Manual (AFM)

    Within 60 days after the effective date of this AD: Revise the 
existing AFM to incorporate the information specified in Section 05-
