RIN 2120-AA64

Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This 
proposed AD was prompted by a report that during ALTS CAP or (V) ALTS 
CAP mode, the flight guidance/autopilot does not account for engine 
failure while capturing an altitude. This proposed AD would require 
revising the existing airplane flight manual (AFM) to provide the 
flightcrew with new warnings for ``Autoflight'' and ``Engine Failure in 
Climb During ALTS CAP.'' The FAA is proposing this AD to address the 
unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by December 
23, 2019.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-12, dated April 3, 
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.
    This proposed AD was prompted by a report that during ALTS CAP or 
(V) ALTS CAP mode, the flight guidance/autopilot does not account for 
engine failure while capturing an altitude. The FAA is proposing this 
AD to address the occurrence of an engine failure during or before a 
climb while in ALTS CAP or (V) ALTS CAP mode, as it could cause the 
airspeed to drop significantly below the safe operating speed and may 
require prompt flightcrew intervention to maintain a safe operating 
speed. See the MCAI for more information.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information, which 
provides new warnings for ``Autoflight'' and ``Engine Failure in Climb 
During ALTS CAP,'' in the LIMITATIONS--System Limitations and the 
EMERGENCY PROCEDURES--Powerplant sections of the applicable AFM.
     Bombardier Challenger 300, Airplane Flight Manual, 
Publication No. CSP 100-1, Revision 55, dated April 8, 2019.
     Bombardier Challenger 350, Airplane Flight Manual, 
Publication No. CH 350 AFM, Revision 21, dated April 8, 2019.
    These documents are distinct since they apply to different airplane 
models in different configurations. 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.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to a bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI and 
service information referenced above. The FAA is proposing this AD 
because the agency evaluated all the relevant information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require revising the existing AFM with new 
warnings for ``Autoflight'' and ``Engine Failure in Climb During ALTS 
CAP,'' in the LIMITATIONS--System Limitations and the EMERGENCY 
PROCEDURES--Powerplant sections, as described previously.

Costs of Compliance

    The FAA estimates that this proposed AD affects 252 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed 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.
    This proposed 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 the 
Director of the System Oversight Division.

Regulatory Findings

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (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.
