2020-11-10 BOMBARDIER, INC.: Amendment 39-19914; Docket No. FAA-2019-1076; Product Identifier 2019-NM-173-AD.
(a) EFFECTIVE DATE

    This AD is effective July 14, 2020.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This  AD applies  to  Bombardier, Inc.,  Model  BD-100-1A10 airplanes,
    certificated  in any category,  serial numbers 20003 through 20788 in-
    clusive.

(d) SUBJECT

    Air Transport Association (ATA) of America Code 27, Flight controls.

(e) REASON

    This AD was prompted by a report of an in-flight event where a flight-
    crew observed a  SPOILER FAIL message  and had difficulty  maintaining
    roll control of the  airplane. The FAA is  issuing this AD to  address
    uncommanded  deployment  of  the  multi-function  spoiler  at  certain
    positions,  which  in  combination with  specific  flap  positions and
    airspeeds, could  create an  unacceptably high  flightcrew workload in
    maintaining roll control  of the airplane  and could possibly  lead to
    loss of controllability of the airplane.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) AIRPLANE FLIGHT MANUAL (AFM) REVISIONS

    Within 30 days  after the effective date  of this AD:  Revise the Non-
    Normal Procedures section of the existing AFM  to incorporate  the in-
    formation in Section 05-23,  "Flight Controls,"  of the applicable AFM
    specified in figure 1 to paragraph (g) of this AD.

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 BD-100-1A10 airplanes. This AD was
prompted by a report of an in-flight event where a flightcrew observed
a SPOILER FAIL message and had difficulty maintaining roll control of
the airplane. This AD requires revising the existing airplane flight
manual (AFM) to provide the flightcrew with procedures related to roll
spoiler failures that reduce the flightcrew workload during this type
of failure scenario. The FAA is issuing this AD to address the unsafe
condition on these products.

DATES: This AD is effective July 14, 2020.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 14,
2020.

ADDRESSES: For service information identified in this final rule,

SUPPLEMENTARY INFORMATION:

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-29, dated August
12, 2019 (also referred to 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-2019-1076.
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 22, 2020 (85 FR 3553). The NPRM was prompted by a
report of an in-flight event where a flightcrew observed a SPOILER FAIL
message and had difficulty maintaining roll control of the airplane.
The NPRM proposed to require revising the existing AFM to provide the
flightcrew with procedures related to roll spoiler failures that reduce
the flightcrew workload during this type of failure scenario. The FAA
is issuing this AD to address uncommanded deployment of the multi-
function spoiler at certain positions, which in combination with
specific flap positions and airspeeds, could create an unacceptably
high flightcrew workload in maintaining roll control of the airplane
and could possibly lead to loss of controllability of the airplane. See
the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comment received
on the NPRM and the FAA's response to that comment.

Request To Use the Latest Service Information


Net Jets requested that the FAA use the latest service information.
Net Jets stated that Bombardier has released Challenger 350 Airplane
Flight Manual, Publication No. CH 350 AFM, Revision 24, dated January
15, 2020.
The FAA agrees to clarify. Paragraph (g) of this AD specifies to
revise the Non-Normal Procedures section of the existing AFM to
incorporate the information in Section 05-23, ``Flight Controls,'' of
Bombardier Challenger 350, Airplane Flight Manual, Publication No. CH
350 AFM, Revision 22, dated July 8, 2019 (for the applicable
airplanes). The language in paragraph (g) of this AD is designed to
allow incorporating the specific information in Section 05-23,
regardless of the revision level of the AFM, so long as the language is
identical to the information in Section 05-23, ``Flight Controls,''
Revision 22. The FAA has not changed this AD in this regard.

Conclusion

The FAA reviewed the relevant data, considered the comment
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

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 Challenger 300 Airplane Flight Manual,
Publication No. CSP 100-1, Revision 56, dated July 8, 2019; and
Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM,
Revision 22, dated July 8, 2019. This service information describes
non-normal procedures for flight controls. These documents are distinct
since they apply to different airplane serial numbers. 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 577 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 x $85 per hour = $85
$0
$85
$49,045

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.
