14 CFR Part 39
[Docket No. FAA-2005-22749; Directorate Identifier 2005-NM-188-AD;
Amendment 39-14455; AD 2006-02-03]
RIN 2120-AA64
Airworthiness Directives; Raytheon Model Hawker 800XP 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 Raytheon Model Hawker 800XP airplanes. This AD requires
inspecting to determine if the correct fuse is installed on the
hydraulic over-temperature switch on panel ZK in the rear equipment
bay, and replacing the existing fuse if necessary. This AD results from
a report of the installation of an incorrect fuse on the over-
temperature switch on panel ZK in the rear equipment bay during
airplane maintenance. We are issuing this AD to prevent a short circuit
in the fuse and consequent heat damage to associated wiring and
surrounding equipment, which could result in smoke or fire on the
airplane.
DATES: This AD becomes effective February 24, 2006.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of February 24,
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 Raytheon Model
Hawker 800XP airplanes. That NPRM was published in the Federal Register
on October 27, 2005 (70 FR 61914). That NPRM proposed to require
inspecting to determine if the correct fuse is installed on the
hydraulic over-temperature switch on panel ZK in the rear equipment
bay, and replacing the existing fuse 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.
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 138 airplanes of the affected design in the
worldwide fleet. This AD will affect about 110 airplanes of U.S.
registry. The required actions will take about 2 work hours per
airplane, at an average labor rate of $65 per work hour. Required parts
cost is negligible. Based on these figures, the estimated cost of the
AD for U.S. operators is $14,300, or $130 per airplane.
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.

determine if a 20-amp fuse is installed on the hydraulic over-
temperature switch on panel ZK in the rear equipment bay in
accordance with the Accomplishment Instructions of Raytheon Service
Bulletin SB 24-3724, dated May 2005. If a 20-amp fuse is installed,
before further flight, replace it with a 3-amp fuse in accordance
with the Accomplishment Instructions of the service bulletin.
Note 1: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
enhance visual access to all exposed surfaces in the inspection
area. This level of inspection is made under normally available
lighting conditions such as daylight, hangar lighting, flashlight,
or droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
Note 2: A note in the Accomplishment Instructions of the
Raytheon service bulletin instructs operators to contact Raytheon if
any difficulty is encountered in accomplishing the service bulletin.
However, any deviation from the instructions provided in the service
bulletin must be approved as an alternative method of compliance
(AMOC) under paragraph (g) of this AD.
Repair Approval
(g) Where the Raytheon Service Bulletin SB 24-3724, dated May
2005, says to contact the manufacturer if any sign of damage is
found on associated terminals and wires: Before further flight,
contact the Manager, Wichita Aircraft Certification Office, FAA, for
applicable repair actions; then, before further flight, accomplish
the applicable repair actions specified, according to a method
approved by the Manager, Wichita Aircraft Certification Office.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, Wichita Aircraft Certification Office, has
the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
