(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. As of the effective date of this AD ................... Not applicable. Not Applicable .................................................. Procedures Not Applicable. 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. See Caution note in GROB Service Bulletin MSB306–38, dated February 12, 2004.

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.

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.

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.
    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.

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 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 that the 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); 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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.
