(5) Do not install any spherical locking bolt, P/N
102–3500.21 (or FAA-approved equivalent
part number), that does not have revision letter ‘‘b’’ permanently marked on the bottom of
the bolt.
(6) 14 CFR 21.303 allows for replacement parts
through parts manufacturer approval (PMA).
The phrase ‘‘or FAA-approved equivalent part
number’’ in this AD is intended to signify
those parts that are PMA parts approved
through identicality to the design of the part
under the type certificate and replacement
parts to correct the unsafe condition under
PMA (other than identicality). If parts are installed that are identical to the unsafe parts,
then the corrective actions of the AD affect
these parts also. In addition, equivalent replacement parts to correct the unsafe condition under PMA (other than identicality) may
also be installed provided they meet current
airworthiness standards, which include those
actions cited in this AD.

Note: During ground handling, it has been
noted that a tendency exists for the ground
crew to move these gliders by using the
horizontal stabilizer as a lifting point. This
practice may facilitate damage to the
stabilizer assembly and should be avoided.

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Gulfstream Model GV and GV–
SP series airplanes. This proposed AD
would require repairing the force link
assembly wire harness. This proposed
AD results from a report indicating that
the wiring harness outer shield and
insulation on the primary conductors
may have been inadvertently cut due to
an improper method used to remove the
wiring outer jacket. We are proposing
this AD to prevent the loss of the
hardover prevention system (HOPS) in
the roll axis due to a short circuit in the
wiring harness, which could result in
reduced controllability of the airplane.
DATES: We must receive comments on
this proposed AD by July 21, 2006.

proposed AD.

Model GIV–X series airplane, a
technician noticed that the wiring
harness outer shield and insulation on
the primary conductors were cut. The
cuts did not appear to sever the
electrical wire core, but the potential for
severed wires prompted an investigation
by the force link supplier. The
investigation revealed that an improper
method had been used to remove the
wiring outer jacket on approximately
221 affected force links. If this condition
causes the hardover prevention system
(HOPS) to fire inadvertently, the HOPS
would shut down the hydraulics system
in that axis, increasing pilot workload.
Also, an electrical short circuit in the
wiring harness could result in loss of
the HOPS in the roll axis, and
consequent reduced controllability of
the airplane.

We have reviewed Gulfstream G500
Customer Bulletin 14 and G550
Customer Bulletin 14 (for Model GV–SP
series airplanes), and Gulfstream GV
Customer Bulletin 135 (for Model GV
series airplanes), all dated June 23,
2005. The customer bulletins describe
procedures for repairing the force link
assembly wire harness. The repair
includes installing new wiring, visually
inspecting the seal around the wires for
nicks and other damage, and visually
inspecting the mating ends of the
connectors to ensure the contacts are
properly inserted. Accomplishing the
actions specified in the service
information is intended to adequately
address the unsafe condition.
The Gulfstream customer bulletins
include Vought Service Bulletin SB–
VAIGV/GVSP–27–PG0098, dated May 9,
2005, as an additional source of service
information for the repair.
FAA’s Determination and Requirements
of the Proposed AD
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to exist or
develop on other airplanes of this same
type design. For this reason, we are
proposing this AD, which would require
accomplishing the actions specified in
the service information described
previously, except as discussed below.
Clarification of Proposed Repair
Requirements
The service bulletins do not provide
corrective action for nicks or other
damage found during the inspection of
the environmental seal around the
installed wires. This proposed AD
would require operators to repair those
conditions using a method approved by
the FAA.
Costs of Compliance
There are about 99 airplanes of the
affected design in the worldwide fleet.
The following table provides the
estimated costs for U.S. operators to
comply with this proposed AD.

is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on

national Government and the States, or
on the distribution of power and

2. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and

Discussion
While installing an aileron force link assembly during the
production of a Model GIV-X series airplane, a technician noticed that
the wiring harness outer shield and insulation on the primary
conductors were cut. The cuts did not appear to sever the electrical
wire core, but the potential for severed wires prompted an
investigation by the force link supplier. The investigation revealed
that an improper method had been used to remove the wiring outer jacket
on approximately 221 affected force links. If this condition causes the
hardover prevention system (HOPS) to fire inadvertently, the HOPS would
shut down the hydraulics system in that axis, increasing pilot
workload. Also, an electrical short circuit in the wiring harness could
result in loss of the HOPS in the roll axis, and consequent reduced
controllability of the airplane.
Relevant Service Information
We have reviewed Gulfstream G500 Customer Bulletin 14 and G550
Customer Bulletin 14 (for Model GV-SP series airplanes), and Gulfstream
GV Customer Bulletin 135 (for Model GV series airplanes), all dated
June 23, 2005. The customer bulletins describe procedures for repairing
the force link assembly wire harness. The repair includes installing
new wiring, visually inspecting the seal around the wires for nicks and
other damage, and visually inspecting the mating ends of the connectors
to ensure the contacts are properly inserted. Accomplishing the actions
specified in the service information is intended to adequately address
the unsafe condition.

SB-VAIGV/GVSP-27-PG0098, dated May 9, 2005, as an additional source of

short circuit in the wiring harness of the aileron force link
assembly, which could result in reduced controllability of the
airplane.

AD performed within the compliance times specified, unless the
