AD 2019–22–07 requires revising the existing AFM to include a limitation and an abnormal operating procedure for the AFCS. AD 2019–22– 07 resulted from a report that during AFCS ALTS CAP or (V) ALTS CAP mode, the flight guidance/autopilot does not account for engine failure while capturing an altitude. The FAA issued AD 2019–22–07 to address an engine failure, if it occurs during or before a climb while in ALTS CAP or (V) ALTS CAP mode, which may cause the airspeed to drop significantly below the safe operating speed, possibly resulting in reduced control of the airplane. VerDate Sep<11>2014 16:41 Feb 23, 2021 Jkt 253001 Since the FAA issued AD 2019–22– 07, it was found that the limitation and abnormal operating procedure did not include reference to (V) ALTV CAP mode. It was also found that the MHI RJ Aviation ULC Model CL–600–2C11 (Regional Jet Series 550) airplanes are also affected by the same unsafe condition. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF– 2018–32R1, dated August 7, 2020 (also referred to after this as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all MHI RJ Aviation ULC Model CL–600–2B19 (Regional Jet Series 100 & 440), CL–600–2C10 (Regional Jet Series 700, 701 & 702), CL– 600–2C11 (Regional Jet Series 550), CL– 600–2D15 (Regional Jet Series 705), CL– 600–2D24 (Regional Jet Series 900), and CL–600–2E25 (Regional Jet Series 1000) 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–2021–0098. This proposed AD was prompted by a report that found that the limitation and abnormal operating procedure did not include reference to (V) ALTV CAP mode (Model CL–600–2B19 airplanes do not have (V) ALTS CAP or (V) ALTV CAP mode). The risk of the unsafe condition also exists during (V) ALTV CAP mode. The FAA is proposing this AD to address an engine failure, if it occurs during or before a climb while in ALTS CAP, (V) ALTS CAP, or (V) ALTV CAP mode, as applicable, which may cause the airspeed to drop significantly below the safe operating speed, possibly resulting in reduced control of the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information, which describes procedures for revising the existing AFM by including a limitation that specifies a warning for the AFCS and an abnormal operating procedure if an engine failure occurs during or before a climb while in ALTS CAP mode, (V) ALTS CAP mode, or (V) ALTV CAP mode, as applicable. These documents are distinct since they apply to different airplane models. • Subject 2, ‘‘Automatic Flight Control System (AFCS),’’ of Section 02– 08, ‘‘System Limitations,’’ of Chapter 2, ‘‘LIMITATIONS’’; and Subject 1.C, PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 ‘‘Engine Failure in Climb During ALTS CAP,’’ of Section 05–02, ‘‘IN–FLIGHT ENGINE FAILURES,’’ of Chapter 5, ‘‘ABNORMAL PROCEDURES’’; of the Bombardier CRJ Series Regional Jet Model CL–600–2B19 AFM, CSP A–012, Volume 1, Revision 73, dated January 3, 2020. • Subject 2,’’ Automatic Flight Control System (AFCS),’’ of Section 02– 08, ‘‘System Limitations,’’ of Chapter 2, ‘‘LIMITATIONS’’; and Subject 1.C, ‘‘Engine Failure in Climb During ALTS CAP,’’ and Subject 1.D, ‘‘Engine Failure in Climb During (V) ALTS CAP or (V) ALTV CAP,’’ of Section 05–02, ‘‘IN– FLIGHT ENGINE FAILURES,’’ of Chapter 5, ‘‘ABNORMAL PROCEDURES’’; of the Bombardier CRJ Series Regional Jet Model CL–600–2C10 (Series 700, 701, 702) and CL–600–2C11 (Series 550) AFM CSP B–012, Revision 31, dated May 8, 2020. • Subject 2, ‘‘Automatic Flight Control System (AFCS),’’ of Section 02– 08, ‘‘System Limitations,’’ of Chapter 2, ‘‘LIMITATIONS’’; and Subject 1.C, ‘‘Engine Failure in Climb During ALTS CAP,’’ and Subject 1.D, ‘‘Engine Failure in Climb During (V) ALTS CAP or (V) ALTV CAP,’’ of Section 05–02, ‘‘IN– FLIGHT ENGINE FAILURES,’’ of Chapter 5, ‘‘ABNORMAL PROCEDURES’’; of the Bombardier CRJ Series Regional Jet Model CL–600–2D24 (Series 900) and CL–600–2D15 (Series 705) AFM, CSP C–012, Volume 1, Revision 24, dated March 27, 2020. • Subject 2, ‘‘Automatic Flight Control System (AFCS),’’ of Section 02– 08, ‘‘System Limitations,’’ of Chapter 2, ‘‘LIMITATIONS’’; and Subject 1.C, ‘‘Engine Failure in Climb During ALTS CAP,’’ and Subject 1.D, ‘‘Engine Failure in Climb During (V) ALTS CAP or (V) ALTV CAP,’’ of Section 05–02, ‘‘IN– FLIGHT ENGINE FAILURES,’’ of Chapter 5, ‘‘ABNORMAL PROCEDURES’’; of the Bombardier CRJ Series Regional Jet Model CL–600–2E25 (Series 1000) AFM CSP D–012, Revision 23, dated February 14, 2020. 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 E:\FR\FM\24FEP1.SGM 24FEP1 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Proposed Rules 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 Requirements of This NPRM This proposed AD would retain none of the requirements of AD 2019–22–07. This proposed AD would require revising the existing AFM to include reference to (V) ALTV CAP mode, as applicable, in the limitation and an 11167 abnormal operating procedure for the AFCS. Costs of Compliance The FAA estimates that this proposed AD affects 992 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost New proposed actions ............ 1 work-hour × $85 per hour = $85 ......................................... 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. khammond on DSKJM1Z7X2PROD with PROPOSALS Regulatory Findings The FAA has 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 VerDate Sep<11>2014 16:41 Feb 23, 2021 Jkt 253001 under the criteria of the Regulatory Flexibility Act.

Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate 
Previously Held by Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2019-22-07, which applies to all MHI RJ Aviation ULC Model CL-600-2B19 
(Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional 
Jet Series 700, 701 & 702) airplanes, Model CL-600-2D15 (Regional Jet 
Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) 
airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. 
AD 2019-22-07 requires revising the existing airplane flight manual 
(AFM) to include a limitation and an abnormal operating procedure for 
the Automatic Flight Control System (AFCS). Since the FAA issued AD 
2019-22-07, it was found that the limitation and abnormal operating 
procedure did not include reference to a certain mode. This proposed AD 
would require revising the existing AFM and adding airplanes to the 
applicability. 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 April 12, 
2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The FAA issued AD 2019-22-07, Amendment 39-19786 (85 FR 439, 
January 6, 2020) (AD 2019-22-07), for all MHI RJ Aviation ULC Model CL-
600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 
(Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2D15 
(Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet 
Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) 
airplanes. AD 2019-22-07 requires revising the existing AFM to include 
a limitation and an abnormal operating procedure for the AFCS. AD 2019-
22-07 resulted from a report that during AFCS ALTS CAP or (V) ALTS CAP 
mode, the flight guidance/autopilot does not account for engine failure 
while capturing an altitude. The FAA issued AD 2019-22-07 to address an 
engine failure, if it occurs during or before a climb while in ALTS CAP 
or (V) ALTS CAP mode, which may cause the airspeed to drop 
significantly below the safe operating speed, possibly resulting in 
reduced control of the airplane.

Actions Since AD 2019-22-07 Was Issued

    Since the FAA issued AD 2019-22-07, it was found that the 
limitation and abnormal operating procedure did not include reference 
to (V) ALTV CAP mode. It was also found that the MHI RJ Aviation ULC 
Model CL-600-2C11 (Regional Jet Series 550) airplanes are also affected 
by the same unsafe condition.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2018-32R1, dated August 7, 
2020 (also referred to after this as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 
& 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 
(Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-
600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet 
Series 1000) 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-2021-0098.
    This proposed AD was prompted by a report that found that the 
limitation and abnormal operating procedure did not include reference 
to (V) ALTV CAP mode (Model CL-600-2B19 airplanes do not have (V) ALTS 
CAP or (V) ALTV CAP mode). The risk of the unsafe condition also exists 
during (V) ALTV CAP mode. The FAA is proposing this AD to address an 
engine failure, if it occurs during or before a climb while in ALTS 
CAP, (V) ALTS CAP, or (V) ALTV CAP mode, as applicable, which may cause 
the airspeed to drop significantly below the safe operating speed, 
possibly resulting in reduced control of the airplane. See the MCAI for 
additional background information.

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

[[Page 11167]]

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 Requirements of This NPRM

    This proposed AD would retain none of the requirements of AD 2019-
22-07. This proposed AD would require revising the existing AFM to 
include reference to (V) ALTV CAP mode, as applicable, in the 
limitation and an abnormal operating procedure for the AFCS.

Costs of Compliance

    The FAA estimates that this proposed AD affects 992 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 has 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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
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:

mode, the flight guidance/autopilot does not account for engine 
failure while capturing an altitude. The FAA is issuing this AD to 
address an engine failure, if it occurs during or before a climb 
while in ALTS CAP, (V) ALTS CAP, or (V) ALTV CAP mode, which may 
cause the airspeed to drop significantly below the safe operating 
speed, possibly resulting in reduced control of the airplane.

(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
