2022-19778. 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 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.

Costs of Compliance

The FAA estimates that this AD affects 123 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	$10,455

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.
