Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for all
Gulfstream Aerospace Corporation
Model G–IV airplanes. This proposed
AD was prompted by a report indicating
that the G–IV gust lock system allows
more throttle travel than was intended
and could allow the throttle to be
advanced to reach take-off thrust. This
proposed AD would require
modification of the gust lock system,
and a revision of the maintenance or
inspection program to incorporate
functional tests. We are proposing this
AD to address the unsafe condition on
these products.
DATES: We must receive comments on
this proposed AD by January 26, 2017.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following
methods:
• Federal eRulemaking Portal: Go to

Discussion
We have received a report indicating
that the G–IV gust lock system allows
more throttle travel than was intended
and could allow the throttle to be
advanced to reach take-off thrust. The
intended function of the gust lock
system is to restrict throttle lever
movement to a maximum of 6 degrees
of forward travel, which provides an
unmistakable warning to the pilot that
the gust lock system is still engaged,
prohibiting the use of the primary flight
control surfaces. This condition, if not
corrected, could result in the aircraft
reaching near take-off thrust and high
velocities without primary flight
controls (aileron, elevator, and rudder)
that can cause a failure to rotate and
high-speed runway overrun.

CFR Part 51
We reviewed Gulfstream IV Customer
Bulletin Number 236A, dated August 8,
2016; Gulfstream G300 Customer
Bulletin Number 236A, dated August 8,
2016; and Gulfstream G400 Customer
Bulletin Number 236A, dated August 8,
2016. The service information describes
procedures for modifying the gust lock
system by doing a retrofit of the gust
lock throttle interlock. These documents
are distinct since they apply to different
airplane models.
We reviewed Gulfstream IV
Maintenance Manual Temporary
Revision (TR) 27–3, dated April 29,
2016; Gulfstream IV MSG–3
Maintenance Manual TR 27–3, dated
April 29, 2016; Gulfstream G300

task to do functional tests of the throttle
lever gust lock protection. 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
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 in other products of the same
type design.
Proposed AD Requirements
This proposed AD would require
modification of the gust lock system,
and a revision of the maintenance or
inspection program to incorporate
functional tests of the throttle level gust
lock protection.
Costs of Compliance
We estimate that this proposed AD
affects 425 airplanes of U.S. registry. We
estimate the following costs to comply
with this proposed AD:
ESTIMATED COSTS
Action
Labor cost
Modification and Maintenance or Inspection
Program Revision.
109 work-hours × $85 per hour = $9,265 ......
We have received no definitive data
that would enable us to provide cost
estimates for the on-condition actions
specified in this proposed AD.
According to the manufacturer, some
of the costs of this proposed 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
srobinson on DSK5SPTVN1PROD with PROPOSALS
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 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
VerDate Sep<11>2014

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.

(c) Applicability
This AD applies to all Gulfstream
Aerospace Corporation Model G–IV
airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of
America Code 27, Flight controls.
(e) Unsafe Condition
This AD was prompted by a report
indicating that the G–IV gust lock system
allows more throttle travel than was intended
and could allow the throttle to be advanced
to reach take-off thrust. The intended
function of the gust lock system is to restrict
throttle lever movement to a maximum of 6
degrees of forward travel, which provides an
unmistakable warning to the pilot that the
gust lock system is still engaged, prohibiting
the use of the primary flight control surfaces.
We are issuing this AD to prevent the throttle
lever movement from advancing more than 6
degrees of forward travel, which could result
in the aircraft reaching near take-off thrust
and high velocities without primary flight
controls (aileron, elevator, and rudder) that
can cause a failure to rotate and high speed
runway overrun.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(g) Modification

procedures for a functional test of the throttle lever gust lock
protection. These documents are distinct since they apply to different
airplane models.
We reviewed Gulfstream IV Maintenance Manual TR 5-7, dated April
29, 2016; Gulfstream IV MSG-3 Maintenance Manual TR 5-6, dated April
29, 2016; Gulfstream G300 Maintenance Manual TR 5-3, dated April 29,
2016; and Gulfstream G400 Maintenance Manual TR 5-3, dated April 29,
2016. The service information describes an airworthiness limitation
[[Page 89398]]
(certification maintenance requirement) task to do functional tests of
the throttle lever gust lock protection. 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
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 in other products of the same type design.
Proposed AD Requirements
This proposed AD would require modification of the gust lock
system, and a revision of the maintenance or inspection program to
incorporate functional tests of the throttle level gust lock
protection.
Costs of Compliance
We estimate that this proposed AD affects 425 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Modification and Maintenance or 109 work-hours x $85 per $9,080 $18,345 $7,796,625
Inspection Program Revision. hour = $9,265.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this proposed
AD.
According to the manufacturer, some of the costs of this proposed
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 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 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.

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
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
Gulfstream Aerospace Corporation: Docket No. FAA-2016-9437;
Directorate Identifier 2016-NM-131-AD.
(a) Comments Due Date
We must receive comments by January 26, 2017.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Gulfstream Aerospace Corporation Model G-
IV airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
controls.
(e) Unsafe Condition
This AD was prompted by a report indicating that the G-IV gust
lock system allows more throttle travel than was intended and could
allow the throttle to be advanced to reach take-off thrust. The
intended function of the gust lock system is to restrict throttle
lever movement to a maximum of 6 degrees of forward travel, which
provides an unmistakable warning to the pilot that the gust lock
system is still engaged, prohibiting the use of the primary flight
control surfaces. We are issuing this AD to prevent the throttle
lever movement from advancing more than 6 degrees of forward travel,
which could result in the aircraft reaching near take-off thrust and
high velocities without primary flight controls (aileron, elevator,
and rudder) that can cause a failure to rotate and high speed runway
overrun.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Modification
Within 36 months after the effective date of this AD, modify the
gust lock system by doing a retrofit of the gust lock throttle
interlock, in accordance with the applicable service information
specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD.
