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.

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.
    (2) Before using any AMOC approved in accordance with Sec.  
39.19 on any airplane to which the AMOC applies, notify the 
appropriate principal inspector in the FAA Flight Standards 
Certificate Holding District Office.
