[Docket No. FAA-2009-1180; Directorate Identifier 2009-CE-060-AD]
RIN 2120-AA64

 
Airworthiness Directives; Hawker Beechcraft Corporation (Type 
Certificate Previously Held by Raytheon Aircraft Company) Models B300 
and B300C Airplanes

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

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.

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:

     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:

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 http://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.

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.
