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 Bombardier, Inc., Model
BD–100–1A10 airplanes. The NPRM
published in the Federal Register on
February 28, 2017 (82 FR 12071). The
NPRM was prompted by several reports
of nose wheel steering failures in
service. The NPRM proposed to require
a part verification and replacement of
certain steering manifolds. We are
issuing this AD to prevent moisture
from entering the electrical stage of the
electro-hydraulic servo valve (EHSV),
which, in combination with a steering
selector valve failure, could lead to
uncommanded nose wheel steering, and
a consequent runway excursion at high
speed.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2016–24,
dated August 19, 2016 (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. The MCAI states:
Several cases of nose wheel steering
failures have been reported in service. In one
case, the aeroplane experienced
uncommanded nose wheel steering, resulting
in a runway excursion.
Investigations found the presence of
moisture inside the electrical stage of the
electro-hydraulic servo valve (EHSV) unit,
which resulted in low insulation resistance
and corrosion. This condition, in
combination with a steering selector valve
failure, could result in uncommanded nose
wheel steering, which could lead to a runway
excursion at high speed.
This [Canadian] AD mandates the
replacement of the steering manifold to
provide better moisture ingress protection of
the EHSV.
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–2017–
0124.
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.
Related Service Information Under 1
CFR Part 51
We reviewed Bombardier Service
Bulletin 100–32–25, Revision 01, dated
June 30, 2015. This service information
describes procedures for a one-time
verification of the steering manifold part
number and replacement of the steering
manifold and mod plate. 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 161
airplanes of U.S. registry.
We estimate the following costs to
comply with this AD:

Labor cost
Parts cost
Cost per
product
Cost on U.S.

cost impact on affected individuals. We
do not control warranty coverage for
affected individuals. As a result, we
have included all costs in our cost
estimate.

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
PO 00000
Frm 00014

Sfmt 4700
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
E:\FR\FM\06JNR1.SGM
06JNR1
Federal Register / Vol. 82, No. 107 / Tuesday, June 6, 2017 / Rules and 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.

Discussion
On October 20, 2016, at 81 FR 72552,
the Federal Register published our
notice of proposed rulemaking (NPRM),
which proposed to amend 14 CFR part
39 by adding an AD that would apply
to NavWorx ADS–B Model ADS600–B
units, part number (P/N) 200–0012 and
P/N 200–0013, and Model ADS600–EXP
units, P/N 200–8013. The NPRM
proposed to require removing the ADS–
B unit before further flight and proposed
to prohibit installing the affected ADS–
B unit on any aircraft. The NPRM was
prompted by a design change that
resulted in the ADS–B units
broadcasting a Source Integrity Level
(SIL) of 3 instead of 0. A broadcast of
SIL 0 is required because of the
uncertified Global Positioning System
(GPS) source included in the unit. The
proposed actions were intended to
prevent an ADS–B unit from
communicating unreliable position
information to Air Traffic Control (ATC)
and nearby aircraft and a subsequent
aircraft collision.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received approximately 200 comments,
mostly from individuals but also from
NavWorx and organizations such as the
Aircraft Owners and Pilots Association
(AOPA), the Experimental Aircraft
Association (EAA), and the Aircraft
Electronics Association (AEA). The
following presents the comments
received on the NPRM and the FAA’s
response to each comment.
A. Support for the NPRM
Five individual commenters
supported the NPRM.
B. Comments Regarding the FAA’s
Justification of the Unsafe Condition
Several commenters, including
AOPA, requested that the FAA provide
more information about the events that
prompted this AD and the technical
aspects surrounding the unsafe
condition. We agree.
PO 00000
Frm 00016
Fmt 4700
Sfmt 4700
Request: AOPA requested the FAA
clarify whether the internal position
source in the ADS–B units meets the
performance requirements in Appendix
B to Advisory Circular (AC) 20–165B. In
support of this request, AOPA stated the
FAA’s contention that NavWorx did not
present any data substantiating its SIL
change is contrary to NavWorx’s public
statements that its testing verified the
position source met the integrity levels
required by the regulations. Similarly,
NavWorx commented on the AD and
maintained it has provided the FAA
with data demonstrating the internal
GPS met the requirements to transmit a
SIL of 3.
FAA Response: NavWorx has not
demonstrated to the FAA that the
internal position source meets the
performance requirements in Appendix
B to AC 20–165B 1 for a SIL of 3. The
design specifications for NavWorx’s P/N
200–0012 and 200–0013 ADS–B units
identify the internal GPS source for
those units as an uncertified SiRF IV
GPS. The SiRF IV is a commercial grade
chipset not manufactured under an FAA
Technical Standard Order (TSO). AC
20–165B requires the SIL be set at 0
when the ADS–B is integrated with an
uncertified GPS source. When NavWorx
submitted its software upgrade changing
the SIL value from 0 to 3, no hardware
design changes associated with the SIL
value change were made to the ADS–B
units and no testing data substantiating
that SIL change was provided to the
FAA. The only justification NavWorx
cited for the software change was the
FAA’s termination of Traffic
Information Service—Broadcast (TIS–B)
services to aircraft broadcasting ADS–B
with a SIL of 0. This data is available
for review in Docket No. FAA–2016–
9226.
Request: AOPA requested the FAA
clarify its meaning of ‘‘uncertified GPS
source’’ since NavWorx has design
approval through STC No. SA11172SC
to install the ADS–B unit with the
internal GPS on type-certificated
aircraft, and since a compliant position
source does not need to meet a specific
TSO to meet the requirements set forth
in Appendix B of AC 20–165B.
Some commenters requested the FAA
explain why it approved NavWorx’s
ADS–B units at all if the internal,
uncertified GPS source is objectionable.
Many commenters stated the NavWorx
ADS–B units meet the performance and
accuracy/integrity standards of TSO C–
154c; others noted that NavWorx has
stated its testing showed the units meet
the requirements to broadcast a SIL of

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 Bombardier, Inc.,
Model BD-100-1A10 airplanes. The NPRM published in the Federal Register
on February 28, 2017 (82 FR 12071). The NPRM was prompted by several
reports of nose wheel steering failures in service. The NPRM proposed
to require a part verification and replacement of certain steering
manifolds. We are issuing this AD to prevent moisture from entering the
electrical stage of the electro-hydraulic servo valve (EHSV), which, in
combination with a steering selector valve failure, could lead to
uncommanded nose wheel steering, and a consequent runway excursion at
high speed.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-24, dated August 19, 2016 (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. The MCAI states:
Several cases of nose wheel steering failures have been reported
in service. In one case, the aeroplane experienced uncommanded nose
wheel steering, resulting in a runway excursion.
Investigations found the presence of moisture inside the
electrical stage of the electro-hydraulic servo valve (EHSV) unit,
which resulted in low insulation resistance and corrosion. This
condition, in combination with a steering selector valve failure,
could result in uncommanded nose wheel steering, which could lead to
a runway excursion at high speed.
This [Canadian] AD mandates the replacement of the steering
manifold to provide better moisture ingress protection of the EHSV.
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-2017-
0124.
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.
Related Service Information Under 1 CFR Part 51
We reviewed Bombardier Service Bulletin 100-32-25, Revision 01,
dated June 30, 2015. This service information describes procedures for
a one-time verification of the steering manifold part number and
replacement of the steering manifold and mod plate. 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 161 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Steering manifold part 1 work-hour x $85 per $0............................ $85........................... $13,685.
verification. hour = $85.
Replacement of steering manifold.. Up to 4 work-hours x Up to $18,522................. Up to $18,862................. Up to $3,036,7823.
$85 per hour = $340.
--------------------------------------------------------------------------------------------------------------------------------------------------------
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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
[[Page 25945]]
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.
