Airworthiness Directives; Hawker Beechcraft Corporation (Type 
Certificate No. A00010WI Previously Held by Raytheon Aircraft Company) 
Model 390 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 Model 390 airplanes. This 
proposed AD would require inspecting for installation of certain serial 
number (S/N) starter generators and replacing the starter generator if 
one with an affected serial number is found. This proposed AD results 
from reports that starter generators with deficient armature insulating 
materials may have been installed on certain airplanes. We are 
proposing this AD to detect and replace starter generators with 
defective armature insulating materials. This condition could result in 
the loss of operation of one or both starter generators with consequent 
loss of all non-battery electrical power.

DATES: We must receive comments on this proposed AD by July 6, 2010.

ADDRESSES: Use one of the following addresses to comment on this 
proposed AD:

arguments regarding this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number, ``FAA-
2010-0523; Directorate Identifier 2010-CE-018-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 http://www.regulations.gov, including any personal information you provide. We

receive concerning this proposed AD.

Discussion

    We have received reports that certain serial number starter 
generators with deficient armature insulating materials may have been 
installed on Hawker Beechcraft Corporation Model 390 airplanes. Starter 
generators with deficient armature fabrication may result in loss of 
operation of one or both starter generators in flight.
    This condition could result in the loss of operation of one or both 
starter generators with consequent loss of all non-battery electrical 
power.

Relevant Service Information

    We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB 
24-3963, issued May 2009, and AMETEK Advanced Industries, Inc. 
Mandatory Service Bulletin--Number: 2009-0414, dated April 2009.
    The service information describes procedures for:
     Inspection for starter generators with serial numbers that 
may have the deficient armature materials; and
     Removal and replacement of starter generators with the 
affected serial numbers.

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 an inspection for suspect starter generators and their 
replacement if found.

Costs of Compliance

    We estimate that this proposed AD would affect 213 airplanes in the 
U.S. registry.
    We estimate the following costs to do the proposed inspection:

----------------------------------------------------------------------------------------------------------------
                                                                            Total cost per    Total cost on U.S.
                Labor cost                           Parts cost                airplane            operators
----------------------------------------------------------------------------------------------------------------
.5 work-hour x $85 per hour = $42.50......  Not applicable..............             $42.50           $9,052.50
----------------------------------------------------------------------------------------------------------------

    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 
this replacement:

------------------------------------------------------------------------
                                                        Total cost per
           Labor cost                 Parts cost           airplane
------------------------------------------------------------------------
10 work-hours (5 work-hours per   $4,069 per side =              $8,988
 side) x $85 per hour = $850.      $8,138.
------------------------------------------------------------------------

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.

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Hawker Beechcraft Corporation (Type Certificate No. A00010WI 
Previously Held By Raytheon Aircraft Company): Docket No. FAA-2010-
0523; Directorate Identifier 2010-CE-018-AD.
