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 detect damage of certain wiring in the flight 
compartment, performing corrective actions if necessary, modifying 
certain wiring connections, and revising the airplane flight manual. 
This AD is prompted by reports of miswiring in the power distribution 
system. We are issuing this AD to ensure that the flightcrew is aware 
of the source of battery power for certain equipment, and to prevent 
damage to wiring and surrounding equipment that could result in smoke 
or fire on the airplane.

DATES: This AD becomes effective June 1, 2005.
    The incorporation by reference of certain publications listed in 
the AD is approved by the Director of the Federal Register as of June 
1, 2005.

ADDRESSES: For service information identified in this AD, contact 
Raytheon Aircraft Company, Department 62, P.O. Box 85, Wichita, Kansas 
67201-0085.
    Docket: The AD docket contains the proposed AD, comments, and any 
final disposition. You can examine the 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-

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39 
with an AD for certain Raytheon Model Hawker 800XP airplanes. That 
action, published in the Federal Register on February 2, 2005 (70 FR 
5387), proposed to require inspecting to detect damage of certain 
wiring in the flight compartment, performing corrective actions if 
necessary, modifying certain wiring connections, and revising the 
airplane flight manual.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been submitted on the proposed 
AD 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 45 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

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. See the ADDRESSES section for a location to 
examine the regulatory evaluation.

the airplane flight manual to inform the flightcrew which standby 
batteries provide power to what equipment once the actions in the 
service bulletin have been done.
    (3) Where the service bulletin specifies to report compliance 
information to the manufacturer, this AD does not include that 
requirement.

Inspection

    (g) Within 50 flight hours or 30 days after the effective date 
of this AD, whichever is first: Perform a detailed inspection for 
damage (primarily but not limited to evidence of heat damage) of 
wiring in the

flight compartment, and all applicable corrective actions, by doing 
all actions in Part 1 of the Accomplishment Instructions of the 
service bulletin, except as provided by paragraphs (f)(1) and (f)(3) 
of this AD. Any applicable corrective action must be done before 
further flight.


    Note 1: For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''

Modification

    (h) At the applicable time specified in paragraph (h)(1) or 
(h)(2) of this AD, modify wiring in the flight compartment by doing 
all actions in accordance with Part 2 of the Accomplishment 
Instructions of the service bulletin. Following accomplishment of 
the actions in Part 2 of the service bulletin, before further 
flight, do all actions associated with the functional test, 
including revising the Emergency Procedures section of the Raytheon 
Hawker 800XP Airplane Flight Manual to include the information in 
Temporary Change P/N 140-590032-0005TC7, in accordance with the 
Accomplishment Instructions of the service bulletin.
