SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014–23–06,
Amendment 39–18022 (79 FR 69037,
November 20, 2014) (‘‘AD 2014–23–
06’’). AD 2014–23–06 applied to certain
Bombardier, Inc. Model CL–600–2B19
(Regional Jet Series 100 & 440)
airplanes. The NPRM published in the
Federal Register on October 24, 2016
(81 FR 73042). The NPRM was
prompted by a report indicating that
inboard and outboard hydraulic lines of
the brakes were found connected to the
incorrect ports on the swivel assembly
of the MLG. The NPRM proposed to
require modification of the MLG with an
improved design. We are issuing this
AD to prevent incorrect installation of
the brake hydraulic lines, which could
cause the brakes and the anti-skid
system to operate incorrectly, and result
in catastrophic failure of the airplane
during a high-speed rejected takeoff.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2014–10R1,
dated May 4, 2016 (referred to after this
as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc. Model CL–
600–2B19 (Regional Jet Series 100 &
440) airplanes. The MCAI states:
Cases of inboard and outboard hydraulic
brake lines connected to the incorrect port of
the swivel assembly on the main landing gear
were found in service. Cross-connected brake
hydraulic lines can cause the brakes and/or
the anti-skid system to operate incorrectly.
During a high speed rejected take-off,
inability for the brakes to operate correctly
could be catastrophic. The original issue of
this [Canadian] AD mandated the
modification to prevent inadvertent crossconnection of the inboard and outboard
hydraulic brake lines.
Following the initial release of this
[Canadian] AD, operators reported that the
modifications required by Bombardier
Service Bulletin (SB) 601R–32–110 Rev. NC.,
dated 19 December 2013, still have a
potential for incorrect connection.
Subsequently, the SB has been revised to
introduce a modified design and this
[Canadian] AD revision is issued to mandate
the incorporation of the modified design.
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–2016–
9190.

Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting this AD
as proposed except for minor editorial
changes. We have determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
correcting 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
We reviewed Bombardier Service
Bulletin 601R–32–110, Revision C,
dated May 4, 2016. The service
information describes procedures for
modifying the MLG by installing a block
on the left and right lower aft-wing
planks. 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.
rmajette on DSK2TPTVN1PROD with RULES
Costs of Compliance
We estimate that this AD affects 526
airplanes of U.S. registry.
We also estimate that it will take
about 9 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Required parts will cost
about $190 per product. Based on these
figures, we estimate the cost of this AD
on U.S. operators to be $502,330, or
$955 per product.
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
VerDate Sep<11>2014
14:42 Feb 17, 2017
Jkt 241001
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this rulemaking
action.
Regulatory Findings
We determined that 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. 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.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Gulfstream Aerospace
Corporation Model GVI airplanes. The
NPRM published in the Federal
Register on November 15, 2016 (81 FR
80009). The NPRM was prompted by a
report indicating that there are design
deficiencies in the software used for
monitoring the disconnect for the FCChosted flight controls actuation main
ram LVDT. The NPRM proposed to
require an update of the FCC software.
We are issuing this AD to prevent
undetected actuation of the main ram
LVDT. Undetected actuation of the main
ram LVDT, if not corrected, could result
in mechanical failure of the flight
control surface actuator mechanism
under force fight (the actuator is
working against the intended load
forces), causing primary surface
hardover, spoiler hardover, and loss of
control of the airplane.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the relevant data and
determined that air safety and the
public interest require adopting this AD
as proposed, except for minor editorial
changes. We have determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014-23-06, Amendment 39-18022 (79 FR 69037,
November 20, 2014) (``AD 2014-23-06''). AD 2014-23-06 applied to
certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 &
440) airplanes. The NPRM published in the Federal Register on October
24, 2016 (81 FR 73042). The NPRM was prompted by a report indicating
that inboard and outboard hydraulic lines of the brakes were found
connected to the incorrect ports on the swivel assembly of the MLG. The
NPRM proposed to require modification of the MLG with an improved
design. We are issuing this AD to prevent incorrect installation of the
brake hydraulic lines, which could cause the brakes and the anti-skid
system to operate incorrectly, and result in catastrophic failure of
the airplane during a high-speed rejected takeoff.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-10R1, dated May 4, 2016 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes. The MCAI states:
Cases of inboard and outboard hydraulic brake lines connected to
the incorrect port of the swivel assembly on the main landing gear
were found in service. Cross-connected brake hydraulic lines can
cause the brakes and/or the anti-skid system to operate incorrectly.
During a high speed rejected take-off, inability for the brakes to
operate correctly could be catastrophic. The original issue of this
[Canadian] AD mandated the modification to prevent inadvertent
cross-connection of the inboard and outboard hydraulic brake lines.
Following the initial release of this [Canadian] AD, operators
reported that the modifications required by Bombardier Service
Bulletin (SB) 601R-32-110 Rev. NC., dated 19 December 2013, still
have a potential for incorrect connection. Subsequently, the SB has
been revised to introduce a modified design and this [Canadian] AD
revision is issued to mandate the incorporation of the modified
design.
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-2016-
9190.

Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting this AD as proposed except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for correcting 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
We reviewed Bombardier Service Bulletin 601R-32-110, Revision C,
dated May 4, 2016. The service information describes procedures for
modifying the MLG by installing a block on the left and right lower
aft-wing planks. 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
We estimate that this AD affects 526 airplanes of U.S. registry.
We also estimate that it will take about 9 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $190 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $502,330, or $955 per product.
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.
Regulatory Findings
We determined that 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. 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.
