14 CFR Part 39
[Docket No. FAA-2005-20111; Directorate Identifier 2004-NM-154-AD;
Amendment 39-14207; AD 2005-16-02]
RIN 2120-AA64
Airworthiness Directives; Raytheon Model HS.125 Series 700A
Airplanes, Model BAe.125 Series 800A Airplanes, and Model Hawker 800
and 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 HS.125 series 700A airplanes, Model BAe.125
series 800A airplanes, and Model Hawker 800 and Hawker 800XP airplanes.
This AD requires inspecting to determine the current rating of the
circuit breakers of certain cockpit ventilation and avionics cooling
system blowers; and replacing the circuit breakers and modifying the
blower wiring, as applicable. This AD results from a report indicating
that a blower motor seized up and gave off smoke. We are issuing this
AD to prevent smoke and fumes in the cockpit in the event that a blower
motor seizes and overheats due to excessive current draw.
DATES: Effective September 6, 2005.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of September 6,
2005.
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.
Contact Raytheon Aircraft Company, Department 62, P.O. Box 85,
Wichita, Kansas 67201-0085, for service information identified in this
AD.
FOR FURTHER INFORMATION CONTACT: Philip Petty, Aerospace Engineer,

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may 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) 647-5227) is located on the
plaza level of the Nassif Building at the street address stated in the
ADDRESSES section.
Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to certain
Raytheon Model HS.125 series 700A airplanes, Model BAe.125 series 800A
airplanes, and Model Hawker 800 and Hawker 800XP airplanes. That
supplemental NPRM was published in the Federal Register on May 9, 2005
(70 FR 24341). That supplemental NPRM proposed to require inspecting to
determine the current rating of the circuit breakers of certain cockpit
ventilation and avionics cooling system blowers; and replacing the
circuit breakers and modifying the blower wiring, as applicable.
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 350 airplanes of the affected design in the
worldwide fleet. This AD will affect about 250 airplanes of U.S.
registry. The required inspection will take about 1 work hour per
airplane, at an average labor rate of $65 per work hour. Based on these
figures, the estimated cost of this AD on U.S. operators is $16,250, or
$65 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.
[[Page 44274]]
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.

while accomplishing the service bulletin, this AD requires you to
contact the Manager, Wichita Aircraft Certification Office (ACO),
FAA.
No Reporting Requirement
(h) Although the service bulletin referenced in this AD
specifies to submit certain information to the manufacturer, this AD
does not include this requirement.
