PROPOSED AD BOMBARDIER, INC.: Docket No. FAA-2019-0256; Product Identifier 2019-NM-027-AD.
(a) COMMENTS DUE DATE

    We must receive comments by June 28, 2019.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This  AD  applies  to the  Bombardier,  Inc.  airplanes identified  in
    paragraphs  (c)(1)  through (c)(5)  of  this AD,  certificated  in any
    category, all manufacturer serial numbers.

(1) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes.

(2) Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes.

(3) Model CL-600-2D15 (Regional Jet Series 705) airplanes.

(4) Model CL-600-2D24 (Regional Jet Series 900) airplanes.

(5) Model CL-600-2E25 (Regional Jet Series 1000) airplanes.

(d) SUBJECT

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

(e) REASON

    This AD was prompted by a report  that during Automatic Flight Control
    System (AFCS) ALTS CAP  or  (V) ALTS CAP  mode  the  flight  guidance/
    autopilot  does  not account  for  engine failure  while  capturing an
    altitude. We  are issuing  this AD  to address  an engine failure that
    occurs during  or before  a climb  while in  ALTS CAP  or (V) ALTS CAP
    mode, which  may cause  the airspeed  to drop  significantly below the
    safe operating  speed, possibly  resulting in  reduced control  of the
    airplane.

(f) COMPLIANCE

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

(g) REVISION OF THE AIRPLANE FLIGHT MANUAL (AFM)

    Within 30 days after the effective date of this AD: Revise the AFM  to
    include the information in Subject 2, "Automatic Flight Control System
    (AFCS),"  of  Section  02-08,  "System  Limitations,"  of  Chapter  2,
    "LIMITATIONS," and  Subject C,  "Engine Failure  in Climb  During ALTS
    CAP," or "Engine Failure in Climb During (V) ALTS CAP," of Section  05
    -02, "In-flight Engine Failures," of Chapter 5, "ABNORMAL PROCEDURES,"
    as  applicable,  of  the  applicable AFM  identified  in  figure  1 to
    paragraph (g) of this AD.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes; Model CL-600-2C10 (Regional Jet Series 700, 701 & 702)
airplanes; Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model
CL-600-2D24 (Regional Jet Series 900) airplanes; and Model CL-600-2E25

a report that during Automatic Flight Control System (AFCS) 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 airplane flight manual (AFM) to include a
limitation and abnormal operating procedure for the AFCS. We are
proposing this AD to address the unsafe condition on these products.

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2018-32, dated December
10, 2018 (referred to after this as the Mandatory Continuing
Airworthiness Information, or "the MCAI"), to correct an unsafe
condition for all Bombardier, Inc., Model CL-600-2B19 (Regional Jet
Series 100 & 440) airplanes; Model CL-600-2C10 (Regional Jet Series 700,
701 & 702) airplanes; Model CL-600-2D15 (Regional Jet Series 705) air-
planes; Model CL-600-2D24 (Regional Jet Series 900) airplanes; and Model
CL-600-2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

It was determined that during ALTS CAP or (V) ALTS CAP mode, the
flight guidance/autopilot does not account for engine failure while
capturing an altitude. If an engine failure occurs during or before
a climb while in ALTS CAP or (V) ALTS CAP mode, the airspeed may
drop significantly below the safe operating speed. Prompt crew
intervention may be required to maintain a safe operating speed.

This [Canadian] AD mandates the introduction of a Limitation and
Abnormal procedure to the [airplane flight manual] AFM to address
the above mentioned unsafe condition.

You may examine the MCAI in the AD docket on the internet at http://www.
regulations.gov by searching for and locating Docket No. FAA-2019-0256.

Related Service Information Under 1 CFR Part 51

Bombardier has issued the following service information, which
describes procedures for revising the AFM by including a warning for
the AFCS and procedures if an engine failure occurs during or before a
climb while in ALTS CAP mode or if an engine failure occurs during or
before a climb while in (V) ALTS CAP mode. These documents are distinct
since they apply to different airplane models.

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 our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
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 AFM by including a
warning for the AFCS and procedures if an engine failure occurs during
or before a climb while in ALTS CAP mode and if an engine failure
occurs during or before a climb while in (V) ALTS CAP mode.

Costs of Compliance

We estimate that this proposed AD affects 985 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
AD:

Estimated Costs for Required Actions

Labor cost
Parts cost
Cost per product
Cost on U.S. operators
1 work-hour x $85 per hour = $85
$0
$85
$83,725

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.

We are 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

We 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. Is not a "significant rule" under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979);

3. Will not affect intrastate aviation in Alaska; and

4. 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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

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 (AD):
