Examining the AD Docket DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2019–1076; Product Identifier 2019–NM–173–AD; Amendment 39–19914; AD 2020–11–10] RIN 2120–AA64 Airworthiness Directives; Bombardier, Inc., Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). 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 a report of an in-flight event where a flightcrew observed a SPOILER FAIL message and had difficulty maintaining roll control of the airplane. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with procedures related to roll spoiler failures that reduce the flightcrew workload during this type of failure scenario. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective July 14, 2020. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of July 14, 2020.

SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2019–29, dated August 12, 2019 (also referred to 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 on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 1076. 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 January 22, 2020 (85 FR 3553). The NPRM was prompted by a report of an in-flight event where a flightcrew observed a SPOILER FAIL message and had difficulty maintaining roll control of the airplane. The NPRM proposed to require revising the existing AFM to PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 provide the flightcrew with procedures related to roll spoiler failures that reduce the flightcrew workload during this type of failure scenario. The FAA is issuing this AD to address uncommanded deployment of the multifunction spoiler at certain positions, which in combination with specific flap positions and airspeeds, could create an unacceptably high flightcrew workload in maintaining roll control of the airplane and could possibly lead to loss of 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 following presents the comment received on the NPRM and the FAA’s response to that comment. Request To Use the Latest Service Information Net Jets requested that the FAA use the latest service information. Net Jets stated that Bombardier has released Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, Revision 24, dated January 15, 2020. The FAA agrees to clarify. Paragraph (g) of this AD specifies to revise the Non-Normal Procedures section of the existing AFM to incorporate the information in Section 05–23, ‘‘Flight Controls,’’ of Bombardier Challenger 350, Airplane Flight Manual, Publication No. CH 350 AFM, Revision 22, dated July 8, 2019 (for the applicable airplanes). The language in paragraph (g) of this AD is designed to allow incorporating the specific information in Section 05–23, regardless of the revision level of the AFM, so long as the language is identical to the information in Section 05–23, ‘‘Flight Controls,’’ Revision 22. The FAA has not changed this AD in this regard. Conclusion The FAA reviewed the relevant data, considered the comment received, 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 E:\FR\FM\09JNR1.SGM 09JNR1 35176 Federal Register / Vol. 85, No. 111 / Tuesday, June 9, 2020 / Rules and Regulations • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Bombardier has issued Challenger 300 Airplane Flight Manual, Publication No. CSP 100–1, Revision 56, dated July 8, 2019; and Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, Revision 22, dated July 8, 2019. This service information describes nonnormal procedures for flight controls. These documents are distinct since they apply to different airplane serial numbers. 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 affects 577 airplanes of U.S. registry. The FAA estimates the following costs to comply with this 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 $49,045 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. jbell on DSKJLSW7X2PROD with RULES 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.

Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was 
prompted by a report of an in-flight event where a flightcrew observed 
a SPOILER FAIL message and had difficulty maintaining roll control of 
the airplane. This AD requires revising the existing airplane flight 
manual (AFM) to provide the flightcrew with procedures related to roll 
spoiler failures that reduce the flightcrew workload during this type 
of failure scenario. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective July 14, 2020.

SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-29, dated August 
12, 2019 (also referred to 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 on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2019-
1076.
    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 January 22, 2020 (85 FR 3553). The NPRM was prompted by a 
report of an in-flight event where a flightcrew observed a SPOILER FAIL 
message and had difficulty maintaining roll control of the airplane. 
The NPRM proposed to require revising the existing AFM to provide the 
flightcrew with procedures related to roll spoiler failures that reduce 
the flightcrew workload during this type of failure scenario. The FAA 
is issuing this AD to address uncommanded deployment of the multi-
function spoiler at certain positions, which in combination with 
specific flap positions and airspeeds, could create an unacceptably 
high flightcrew workload in maintaining roll control of the airplane 
and could possibly lead to loss of 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 following presents the comment received 
on the NPRM and the FAA's response to that comment.

Request To Use the Latest Service Information

    Net Jets requested that the FAA use the latest service information. 
Net Jets stated that Bombardier has released Challenger 350 Airplane 
Flight Manual, Publication No. CH 350 AFM, Revision 24, dated January 
15, 2020.
    The FAA agrees to clarify. Paragraph (g) of this AD specifies to 
revise the Non-Normal Procedures section of the existing AFM to 
incorporate the information in Section 05-23, ``Flight Controls,'' of 
Bombardier Challenger 350, Airplane Flight Manual, Publication No. CH 
350 AFM, Revision 22, dated July 8, 2019 (for the applicable 
airplanes). The language in paragraph (g) of this AD is designed to 
allow incorporating the specific information in Section 05-23, 
regardless of the revision level of the AFM, so long as the language is 
identical to the information in Section 05-23, ``Flight Controls,'' 
Revision 22. The FAA has not changed this AD in this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, 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

[[Page 35176]]

     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Challenger 300 Airplane Flight Manual, 
Publication No. CSP 100-1, Revision 56, dated July 8, 2019; and 
Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, 
Revision 22, dated July 8, 2019. This service information describes 
non-normal procedures for flight controls. These documents are distinct 
since they apply to different airplane serial numbers. 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 affects 577 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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

    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.
