14 CFR Part 39

[Docket No. FAA-2022-0398; Project Identifier MCAI-2020-00881-T; 
Amendment 39-22085; AD 2022-12-13]

Airworthiness Directives; Bombardier, Inc., Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), 
and CL-600-2B16 (601-3A and 601-3R Variants) airplanes. This AD was 
prompted by reports that during certain operating modes, the flight 
guidance/autopilot does not account for engine failure while capturing 
an altitude. This AD requires revising the existing airplane flight 
manual (AFM) to provide the flightcrew with a new limitation and 
procedure for operation during certain

[[Page 56260]]

flight modes. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective October 19, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 19, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2020-02, dated February 13, 
2020 (TCCA AD CF-2020-02), to correct an unsafe condition for certain 
Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-
600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes.
    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 CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-
3A, 601-3R, and 604 Variants) airplanes. The NPRM published in the 
Federal Register on April 11, 2022 (87 FR 21037). The NPRM was prompted 
by reports that during certain operating modes, the flight guidance/
autopilot does not account for engine failure while capturing an 
altitude. The NPRM proposed to require revising the existing AFM to 
provide the flightcrew with a new limitation and procedure for 
operation during certain flight modes. The FAA is issuing this AD to 
address a possible engine failure during or before a climb while in 
ALTSEL, ASEL or ALTS CAP mode, which could cause the airspeed to drop 
significantly below the safe operating speed. Prompt crew intervention 
may be required to maintain a safe operating speed.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Change to the Applicability

    Since the FAA issued the NPRM, TCCA revised AD CF-2020-02 and 
issued TCCA AD CF-2020-02R1, dated August 11, 2022 (TCCA AD CF-2020-
02R1) (also referred to as the MCAI). TCCA stated the applicability was 
revised to remove Model CL-600-2B16 (604 Variants) as it was determined 
that these airplanes do not utilize ALTSEL, ASEL and ALTS CAP modes in 
their configurations. TCCA also stated that the AFM references for 
these airplanes were removed from the TCCA AD. You may examine the MCAI 
in the AD docket on the internet at regulations.gov by searching for 
and locating Docket No. FAA-2022-0398.
    The FAA concurs with the change to the applicability because Model 
CL-600-2B16 (604 Variants) airplanes are not affected by the identified 
unsafe condition. The FAA has revised the applicability of this AD 
accordingly. The FAA has also removed the AFM references for these 
airplanes from this final rule and revised the Costs of Compliance 
paragraph in this final rule to specify there are 123 affected U.S. 
airplanes.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
requires adopting this AD as proposed. Except for minor editorial 
changes and the changes described previously, this AD is adopted as 
proposed in the NPRM. None of the changes will increase the economic 
burden on any operator. Accordingly, the FAA is issuing this AD to 
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information. This 
service information contains a new AFM limitation and procedure for 
operation during certain flight modes. These documents are distinct 
since they apply to different airplane configurations. These 
configurations may include the presence or absence of winglets, 
incorporation of service bulletin 601-0300 which introduces an airspeed 
limitation placard, and the type of engine installed on the airplane.

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.

The Amendment

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

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]

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

2022-12-13 Bombardier, Inc.: Amendment 39-22085; Docket No. FAA-
2022-0398; Project Identifier MCAI-2020-00881-T.

(a) Effective Date

    This airworthiness directive (AD) is effective October 19, 2022.

(b) Affected Airworthiness Directives (ADs)

    None.

(c) Applicability

    This AD applies to the Bombardier, Inc., airplanes, certificated 
in any category, identified in paragraphs (c)(1) through (3) of this 
AD.
    (1) Model CL-600-1A11 (600), serial numbers 1001 through 1085 
inclusive.
    (2) Model CL-600-2A12 (601), serial numbers 3001 through 3066 
inclusive.
    (3) Model CL-600-2B16 (601-3A and 601-3R Variants), serial 
numbers 5001 through 5194 inclusive.

(d) Subject

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

(e) Reason

    This AD was prompted by reports that during certain operating 
modes, the flight guidance/autopilot does not account for engine 
failure while capturing an altitude. The FAA is issuing this AD to 
address a possible engine failure during or before a climb while in 
ALTSEL, ASEL or ALTS CAP mode, which could cause the airspeed to 
drop significantly below the safe operating speed. Prompt crew 
intervention may be required to maintain a safe operating speed.

(f) Compliance

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

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

    Within 30 days after the effective date of this AD: Revise the 
existing AFM to incorporate the information specified in the 
limitation and procedure specified in the applicable AFM specified 
in figure 1 to paragraph (g) of this AD.
