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 BD-100-1A10 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 to 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 July 21, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 21, 
2020.

SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-24, dated July 5, 
2019 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc., Model BD-100-1A10 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-
1081.
    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 BD-100-1A10 airplanes. The NPRM published in the Federal 
Register on January 27, 2020 (85 FR 4614). 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 airplane flight manual (AFM) 
to provide the flightcrew with procedures to 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. Two commenters indicated support for the 
NPRM. The following presents the comments received on the NPRM and the 
FAA's response to each comment.

Request To Allow Operators To Use Current AFM Revision

    NetJets Inc. requested it be allowed to use Bombardier Challenger 
350 Airplane Flight Manual (AFM), Publication No. CH 350 AFM, Revision 
24, dated January 15, 2020, for accomplishing the proposed actions. The 
proposed AD referred to Revision 22, dated July 8, 2019.
    The FAA acknowledges the commenter's request and provides the 
following clarification: This AD requires including the information 
that is provided in the referenced AFM revisions in paragraph (g) of 
this AD. The language in paragraph (g) of this AD is designed to allow 
incorporating the specific information, regardless of the revision 
level of the AFM in use, provided the language is identical to the 
referenced AFM revisions specified in paragraph (g) of this AD. The 
language in the latest AFM revisions is the same. We have not changed 
this AD in this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
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

[[Page 36319]]

     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 
provides a procedure for ``Unreliable Airspeed'' in the Emergency 
Procedures section, and also provides a procedure for ``Go-Around'' in 
the Normal Procedures section of the applicable AFM. These documents 
are distinct since they apply to different airplane models.
     Bombardier Challenger 300 AFM, Publication No. CSP 100-1, 
Revision 56, dated July 8, 2019.
     Bombardier Challenger 350 AFM, Publication No. CH 350 AFM, 
Revision 22, dated July 8, 2019.
    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.

Costs of Compliance

    The FAA estimates that this AD affects 560 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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

    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.
