SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Hawker Beechcraft Corporation (type certificate previously held by
Raytheon Aircraft Company) Models B300 and B300C airplanes. This AD
requires you to inspect the terminal board on the circuit card rack
assembly to determine if the correct bus bar is installed and replace
if necessary. This AD also requires you to do an operational check of
the left and right pitot heat annunciators for proper operation and
take corrective action as necessary. This AD results from reports of
the left and right pitot heat annunciators not illuminating for an
inoperative pitot heat condition. We are issuing this AD to detect and
correct installation of an incorrect bus bar, which could result in
failure of the pitot heat annunciators to illuminate. This failure
could lead to the pilot being unaware that moisture has frozen on the
pitot tube(s) and cause erroneous flight instrument indication.
DATES: This AD becomes effective on April 8, 2010.
On April 8, 2010, the Director of the Federal Register approved the
incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION:
Discussion
On December 8, 2009, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain Hawker Beechcraft Corporation Models B300 and
B300C airplanes. This proposal was published in the Federal Register as
a notice of proposed rulemaking (NPRM) on December 17, 2009 (74 FR
66924). The NPRM proposed to require inspecting the terminal board on
the circuit card rack assembly to determine if the correct bus bar is
installed and replacing if necessary. The NPRM also proposed to require
doing an operational check of the left and right pitot heat
annunciators for proper operation and taking corrective action as
necessary.
Comments
We provided the public the opportunity to participate in developing
this AD. We received no comments on the proposal 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
except for minor editorial corrections. We have determined that these
minor corrections:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD will affect 131 airplanes in the U.S.
registry.
We estimate the following costs to do the operational check:
----------------------------------------------------------------------------------------------------------------
Total cost
Labor cost Parts cost Total cost on U.S.
per airplane operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85................ Not applicable.................... $85 $11,135
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary placard
fabrication and installation that will be required based on the results
of the operational check. We have no way of determining the number of
airplanes that may need the placard:
[[Page 9754]]
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per airplane
------------------------------------------------------------------------
.5 work-hour x $85 per hour = Not applicable....... $42.50
$42.50.
------------------------------------------------------------------------
We estimate the following costs to do the inspection of the
terminal board:
----------------------------------------------------------------------------------------------------------------
Total cost
Labor cost Parts cost Total cost on U.S.
per airplane operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85................ Not applicable.................... $85 $11,135
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that will be required based on the results of the inspection of the
terminal board. We have no way of determining the number of airplanes
that may need to replace the bus bar:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per airplane
------------------------------------------------------------------------
3 work-hours x $85 per hour = $255.......... $50 $305
------------------------------------------------------------------------
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 AD.
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 the 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 summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2009-1180; Directorate Identifier 2009-CE-060-AD'' in your
request.
