ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (type certificate previously held by Raytheon Aircraft Company) Models B300 and B300C airplanes. This proposed AD would require you to inspect the terminal board on the circuit card rack assembly to determine if the correct bus bar is installed. This proposed AD would also require you to replace the bus bar if necessary and inspect the left and right pitot heat annunciators for proper operation. This proposed AD results from reports of the left and right pitot heat annunciators not illuminating for an inoperative pitot heat condition. We are proposing 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: We must receive comments on this proposed AD by February 1, 2010. ADDRESSES: Use one of the following addresses to comment on this proposed AD:Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments regarding this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number, ``FAA- 2009-1180; Directorate Identifier 2009-CE-060-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed AD. We will consider all comments received by the closing date and may amend the proposed AD in light of those comments. We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD. Discussion We have received reports indicating that there was a discrepancy between the installation drawing and the wiring diagram for installing the bus bar for the pitot heat annunciators on Hawker Beechcraft Corporation Models B300 and B300C airplanes. Installing the incorrect bus bar creates a condition where the left and right pitot heat annunciators may not illuminate for an inoperative pitot heat condition. This condition, if not corrected, 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. Relevant Service Information We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB 31-3948, Issued: April 2009. The service information describes procedures for: Inspecting the left and right pitot heat annunciators for proper operation; Inspecting the terminal board on the circuit card rack assembly to determine if the correct bus bar is installed; and Replacing the bus bar if necessary. FAA's Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would require inspecting the terminal board on the circuit card rack assembly to determine if the correct bus bar is installed. This proposed AD would also require replacing the bus bar if necessary and inspecting the left and right pitot heat annunciators for proper operation. Costs of Compliance We estimate that this proposed AD would affect 131 airplanes in the U.S. registry. We estimate the following costs to do the proposed operational check: [[Page 66925]] ---------------------------------------------------------------------------------------------------------------- Total cost per Total cost on Labor cost Parts cost airplane U.S. operators ---------------------------------------------------------------------------------------------------------------- 1 work-hour x $80 per hour = $80.............. Not applicable.................. $80 $10,480 ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary placard fabrication and installation that would be required based on the results of the proposed operational check. We have no way of determining the number of airplanes that may need the placard: ------------------------------------------------------------------------ Total cost per Labor cost Parts cost airplane ------------------------------------------------------------------------ .5 work-hour x $80 per hour = $40....... Not applicable $40 ------------------------------------------------------------------------ We estimate the following costs to do the proposed inspection: ---------------------------------------------------------------------------------------------------------------- Total cost per Total cost on Labor cost Parts cost airplane U.S. operators ---------------------------------------------------------------------------------------------------------------- 1 work-hour x $80 per hour = $80.............. Not applicable.................. $80 $10,480 ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We have no way of determining the number of airplanes that may need replacement: ------------------------------------------------------------------------ Total cost per Labor cost Parts cost airplane ------------------------------------------------------------------------ 3 work-hours x $80 per hour = $240...... $50 $290 ------------------------------------------------------------------------ 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: 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 regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. Examining the AD Docket You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at https://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5527) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
