SUBJECT

(d) Air Transport Association of America (ATA) Code 31: Instruments.

UNSAFE CONDITION

(e) 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 the installation of  an
    incorrect bus  bar, which  could result  in failure  of the pitot heat
    annunciators  to  illuminate.  This  failure  could  lead  to moisture
    freezing on the  pitot tube(s) and  cause erroneous flight  instrument
    indication.

COMPLIANCE

(f) To  address this  problem, you  must do  the following, unless already
    done:

    ______________________________________________________________________


    ACTIONS » » »

    (1) Do  an  operational  check  of  the  left  and  right  pitot  heat
        annunciators for illumination.

                Within the next 15 hours time-in-service (TIS) after April

                30 days after  April 8, 2010  (the effective date  of this
                AD), whichever occurs first.

PREAMBLE

AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION: Final rule.

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.

ADDRESSES: For service information identified in this AD, contact Hawker Beechcraft Corporation, Attn: Airline Technical Support, P.O. Box 85, Wichita, Kansas 67201; telephone: (800) 429-5372; fax: (316) 676-8745; Internet: http://www.hawkerbeechcraft.com.

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:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
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:

Labor Cost	Parts Cost	Total Cost Per Airplane	Total Cost on U.S. 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:

Labor Cost	Parts Cost	Total Cost Per Airplane
.5 work-hour X $85 per hour = $42.50	Not applicable	$42.50

We estimate the following costs to do the inspection of the terminal board:

Labor Cost	Parts Cost	Total Cost Per Airplane	Total Cost on U.S. 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:

Labor Cost	Parts Cost	Total 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.
