14 CFR Part 39

[Docket No. FAA-2009-1180; Directorate Identifier 2009-CE-060-AD; 
Amendment 39-16220; AD 2010-05-10]
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: 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.

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:


----------------------------------------------------------------------------------------------------------------
                                                                                                     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:

------------------------------------------------------------------------
                                                             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.
