Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA–2005–22034; Directorate

39–14607; AD 2006–11–03]
RIN 2120–AA64
Airworthiness Directives; Gulfstream
Model GV and GV–SP Series Airplanes
Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for all
Gulfstream Model GV and certain Model
GV–SP series airplanes. This AD
requires a one-time inspection of the left
and right aileron and elevator actuators
to determine the part and serial
numbers of each actuator, repetitive
inspections of suspect actuators to
detect broken damper shafts, and
replacement of any actuator having a
broken damper shaft. This AD also
requires that operators report any
broken damper shaft they find to the
FAA. This AD also requires a
terminating action for the repetitive
inspections. This AD results from
reports of broken or cracked damper
shafts within the aileron and elevator
actuator assemblies. We are issuing this
AD to prevent broken damper shafts,
which could result in locking of an
aileron or elevator actuator (hard-over
condition), which would activate the
hard-over protection system (HOPS),
resulting in increased pilot workload
and consequent reduced controllability
of the airplane.
DATES: This AD becomes effective June
29, 2006.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of June 29, 2006.

Discussion
The FAA issued a supplemental
notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an
AD that would apply to all Gulfstream
Model GV and certain Model GV–SP
series airplanes. That supplemental
NPRM was published in the Federal
Register on March 30, 2006 (71 FR
16066). That supplemental NPRM
proposed to require a one-time
inspection of the left and right aileron
and elevator actuators to determine the
part and serial numbers of each
actuator, repetitive inspections of
suspect actuators to detect broken
damper shafts, and replacement of any
actuator having a broken damper shaft.
That supplemental NPRM also proposed
to require that operators report any
broken damper shaft they find to the
FAA. That supplemental NPRM also
proposed to mandate the previously
optional terminating action.
Comments
We provided the public the
opportunity to participate in the
development of this AD. No comments
have been received on the supplemental
NPRM or on the determination of the
cost to the public.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed in the
supplemental NPRM.
Costs of Compliance
There are about 214 airplanes of the
affected design in the worldwide fleet.
This AD will affect about 174 airplanes
of U.S. registry. The following table
provides the estimated costs for U.S.
operators to comply with this AD.
Gulfstream has stated that it will
provide replacement parts at no cost to
operators.

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 have 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
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
I
PART 39—AIRWORTHINESS
DIRECTIVES
(a) This AD becomes effective June 29,
2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Gulfstream
Model GV series airplanes, and Model GV–

SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Raytheon Model Hawker 800XP
airplanes. This AD requires inspecting
certain bus bars in the DA–A panel to
ensure that the bus bars match the panel
configuration and clearance is adequate
between the bus bars and adjacent
components, and performing corrective
action if necessary. This AD results from
two reports of inadequate clearance
between the bus bars in the DA–A
panel. We are issuing this AD to prevent
insufficient electrical isolation for the
electrical bus configuration and
inability of the flightcrew to isolate the
bus bars in an emergency situation
involving a dual generator failure,
which could result in extra loads on the
main ship batteries and consequent loss
of power to the main essential bus.
DATES: This AD becomes effective June
29, 2006.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of June 29, 2006.

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to certain Raytheon Model
Hawker 800XP airplanes. That NPRM
was published in the Federal Register
on March 7, 2006 (71 FR 11343). That
NPRM proposed to require inspecting
certain bus bars in the DA–A panel to
ensure that the bus bars match the panel
configuration and clearance is adequate
between the bus bars and adjacent
components, and performing corrective
action if necessary.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the NPRM or on the
determination of the cost to the public.
Explanation of Change Made to
Proposed AD
We have clarified the inspection
requirement contained in the proposed
AD. The proposed AD specifies a
detailed inspection. We have revised
this final rule to clarify the definition of
a detailed inspection; Note 1 of this
final rule defines that inspection.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD with the change
described previously. We have
determined that this change will neither
increase the economic burden on any
operator nor increase the scope of the
AD.
Costs of Compliance
There are about 164 airplanes of the
affected design in the worldwide fleet.
This AD will affect about 123 airplanes
of U.S. registry. The required inspection

detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in Subtitle VII,

‘‘General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations

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

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Gulfstream Model GV and certain Model GV-SP series airplanes. This AD
requires a one-time inspection of the left and right aileron and
elevator actuators to determine the part and serial numbers of each
actuator, repetitive inspections of suspect actuators to detect broken
damper shafts, and replacement of any actuator having a broken damper
shaft. This AD also requires that operators report any broken damper
shaft they find to the FAA. This AD also requires a terminating action
for the repetitive inspections. This AD results from reports of broken
or cracked damper shafts within the aileron and elevator actuator
assemblies. We are issuing this AD to prevent broken damper shafts,
which could result in locking of an aileron or elevator actuator (hard-
over condition), which would activate the hard-over protection system
(HOPS), resulting in increased pilot workload and consequent reduced
controllability of the airplane.
DATES: This AD becomes effective June 29, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of June 29, 2006.

Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to all
Gulfstream Model GV and certain Model GV-SP series airplanes. That
supplemental NPRM was published in the Federal Register on March 30,
2006 (71 FR 16066). That supplemental NPRM proposed to require a one-
time inspection of the left and right aileron and elevator actuators to
determine the part and serial numbers of each actuator, repetitive
inspections of suspect actuators to detect broken damper shafts, and
replacement of any actuator having a broken damper shaft. That
supplemental NPRM also proposed to require that operators report any
broken damper shaft they find to the FAA. That supplemental NPRM also
proposed to mandate the previously optional terminating action.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the
supplemental NPRM or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
in the supplemental NPRM.
Costs of Compliance
There are about 214 airplanes of the affected design in the
worldwide fleet. This AD will affect about 174 airplanes of U.S.
registry. The following table provides the estimated costs for U.S.
operators to comply with this AD. Gulfstream has stated that it will
provide replacement parts at no cost to operators.

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 have 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 DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
