2021-11-02 MHI RJ AVIATION ULC (TYPE CERTIFICATE PREVIOUSLY HELD BY BOMBARDIER, INC.): Amendment 39-21564; Docket No. FAA-2021-0098; Project Identifier MCAI-2020-01121-T.
(a) EFFECTIVE DATE

    This airworthiness directive (AD) is effective July 13, 2021.

(b) AFFECTED ADS

    This AD replaces AD 2019-22-07, Amendment 39-19786 (85 FR 439, January
    6, 2020) (AD 2019-22-07).

(c) APPLICABILITY

    This AD  applies  to  the  MHI RJ Aviation ULC airplanes identified in
    paragraphs (c)(1) through (6) of this AD, certificated in any category
    all manufacturer serial numbers.

(1) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes.

(2) Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes.

(3) Model CL-600-2C11 (Regional Jet Series 550) airplanes.

(4) Model CL-600-2D15 (Regional Jet Series 705) airplanes.

(5) Model CL-600-2D24 (Regional Jet Series 900) airplanes.

(6) Model CL-600-2E25 (Regional Jet Series 1000) airplanes.

(d) SUBJECT

    Air Transport Association (ATA) of America Code 22, Auto Flight.

(e) REASON

    This AD was prompted by a report that during the Automatic Flight Con-
    trol System (AFCS) ALTS CAP, (V) ALTS CAP,  or (V) ALTV CAP 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 al-
    ready done.

(g) REVISION OF THE AIRPLANE FLIGHT MANUAL (AFM)

    Within 60 days after the effective date of this AD:  Revise the exist-
    ing AFM to include  the information  in  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," or 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";  as applicable; of the
    applicable AFM identified in figure 1 to paragraph (g) of this AD.

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-22-
07, which applied 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 required revising the existing airplane flight manual
(AFM) to include a limitation and an abnormal operating procedure for
the Automatic Flight Control System (AFCS). This AD requires revising
the existing AFM and adding airplanes to the applicability. This AD was
prompted by a finding that the limitation and abnormal operating
procedure did not include reference to a certain mode. The FAA is
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective July 13, 2021.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 13,
2021.

SUPPLEMENTARY INFORMATION:

Background

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2018-32R1, dated August 21,
2020 (also referred to 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.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2019-22-07, Amendment 39-19786 (85 FR 439,
January 6, 2020) (AD 2019-22-07). AD 2019-22-07 applied 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. The NPRM published in the Federal
Register on February 24, 2021 (86 FR 11165). The NPRM was prompted by a
finding that the limitation and abnormal operating procedure did not include
reference to (V) ALTV CAP mode and a finding that the MHI RJ Aviation ULC
Model CL-600-2C11 (Regional Jet Series 550) airplanes are also affected by
the same unsafe condition (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 NPRM proposed to require revising
the existing AFM and adding airplanes to the applicability. 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.
See the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in
developing this final rule. The FAA has considered the comment
received. The Air Line Pilots Association, International (ALPA) stated
that it supports the NPRM.

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
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 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.

Costs of Compliance

The FAA estimates that this AD affects 992 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
New actions 1 work-hour x $85 per hour = $85
$0
$85
$84,320

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 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.
