14 CFR Part 39

39-19769; AD 2019-21-03]
RIN 2120-AA64


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 of the loss of all air data system information 
provided to the flightcrew, which was caused by icing at high 
altitudes. This AD requires revising the existing airplane flight 
manual (AFM) to provide the flightcrew with procedures for ``Unreliable 
Airspeed'' that stabilize the airplane's airspeed and attitude. The FAA 
is issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective December 18, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 18, 
2019.

SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2018-36, dated December 
27, 2018 (``Canadian AD CF-2018-36'') (also referred to as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Bombardier, Inc., Model CL-600-
1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A and 601-3R 
Variants) 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-2019-0582.
    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 and 601-3R Variants) airplanes. The NPRM published in the Federal 
Register on August 12, 2019 (84 FR 39778). The NPRM was prompted by 
reports of the loss of all air data system information provided to the 
flightcrew, which was caused by icing at high altitudes. The NPRM 
proposed to require revising the existing AFM to provide the flightcrew 
with procedures for ``Unreliable Airspeed'' that stabilize the 
airplane's airspeed and attitude. The FAA is issuing this AD to address 
the loss of all air data system information provided to the flightcrew. 
If not addressed, this condition may adversely affect continued safe 
flight and landing. See the MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Explanation of Change to Format of Paragraph Designation References

    The FAA has revised the format the agency uses for referring to 
paragraph designations throughout this AD. This change is necessary to 
meet the Office of the Federal Register's drafting requirements. For 
example, where the FAA previously referred to paragraphs (g)(1) and 
(g)(2) of this AD, we now refer to paragraphs (g)(1) and (2) of this 
AD. This change does not affect the requirements of this AD.

Conclusion

    The FAA reviewed the relevant data 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.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to

[[Page 61531]]

the Director of the System Oversight Division.

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.
