Airworthiness Directives; Hawker Beechcraft Corporation Model
BH.125 Series 600A Airplanes and Model HS.125 Series 700A Airplanes
Modified in Accordance With Supplemental Type Certificate (STC)
SA2271SW
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Hawker Beechcraft Corporation Model BH.125 series 600A airplanes and
Model HS.125 series 700A airplanes. This AD requires inspecting the
wiring diagrams containing the cockpit blowers and comparing with the
current airplane configuration, and reworking the wiring if necessary.
This AD results from a report indicating that a blower motor of the
cockpit ventilation and avionics cooling system 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: This AD is effective May 14, 2009.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of May 14, 2009.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
certain Hawker Beechcraft Corporation Model BH.125 series 600A
airplanes and Model HS.125 series 700A airplanes. That NPRM was
published in the Federal Register on November 26, 2008 (73 FR 71959).
That NPRM proposed to require inspecting the wiring diagrams containing
the cockpit blowers and comparing with the current airplane
configuration, and reworking the wiring if necessary.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Explanation of Change to Final Rule
We have changed the product identification line to specify the
airplane type certificate holder.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD with the change described
previously. We also determined that this change will not increase the
economic burden on any operator or increase the scope of the AD.
Costs of Compliance
We estimate that this AD affects 40 airplanes of U.S. registry. We
also estimate that it takes about 1 work-hour per product to comply
with this AD. The average labor rate is $80 per work-hour. Based on
these figures, we estimate the cost of this AD to U.S. operators to be
$3,200, or $80 per product.
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
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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.

Hawker Beechcraft Mandatory Service Bulletin SB 24-3850, dated
January 2008; except as provided by paragraph (g) of this AD.
(1) If the current airplane configuration does not match the
applicable cockpit blower wiring diagrams, before further flight,
rework the wiring using a method approved by the Manager, Special
Certification Office, ASW-190, Rotorcraft Directorate, FAA. For the
determination to be approved by the Manager, Special Certification
Office, as required by this paragraph, the Manager's approval letter
must specifically refer to this AD.
(2) If the current airplane configuration matches the applicable
cockpit blower wiring diagrams, before further flight, rework the
wiring in accordance with the Accomplishment Instructions of Hawker
Beechcraft Mandatory Service Bulletin SB 24-3850, dated January
2008.
No Submission of Certain Information
(g) Although Hawker Beechcraft Mandatory Service Bulletin SB 24-
3850, dated January 2008, specifies to submit certain information to
the manufacturer, this AD does not include that requirement.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, Special Certification Office, ASW-190,
Rotorcraft Directorate, FAA, Attn: Andy Shaw, Aerospace Engineer,
Special Certification Office, ASW-190, FAA, Southwest Regional

(817) 222-5188; fax (817) 222-5785; has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19.
(2) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
