DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2006-24951; Directorate Identifier 2005-NM-184-AD;
Amendment 39-14752; AD 2006-18-13]
RIN 2120-AA64

Airworthiness Directives; Gulfstream Model GV and GV-SP Series
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Gulfstream Model GV and GV-SP series airplanes. This AD
requires repairing the force link assembly wire harness. This 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 issuing 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: This AD becomes effective October 13, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of October 13,
2006.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Management Facility, U.S.

Department of Transportation, 400 Seventh Street, SW., Nassif Building,
Room PL-401, Washington, DC.

SUPPLEMENTARY INFORMATION:

Examining the Docket

You may examine the airworthiness directive (AD) docket on the
Internet at http://dms.dot.gov or in person at the Docket Management

Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.

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 Gulfstream
Model GV and GV-SP series airplanes. That NPRM was published in the
Federal Register on June 6, 2006 (71 FR 32487). That NPRM proposed to
require repairing the force link assembly wire harness.

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.

Conclusion

We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.

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 AD.

Estimated Costs
----------------------------------------------------------------------------------------------------------------
Number of U.S.-
Work hours Average labor Parts Cost per registered Fleet cost
rate per hour airplane airplanes
----------------------------------------------------------------------------------------------------------------
3.................... $80 The manufacturer states $240 77 $18,480
that it will supply
required parts to the
operators at no cost.
----------------------------------------------------------------------------------------------------------------

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.
