Amendment 39-16407; AD 2010-17-15]

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: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you 
to inspect for installation of certain serial number (S/N) starter 
generators and replace the starter generator if one with an affected 
serial number is found. This AD results from reports that starter 
generators with deficient armature insulating materials may have been 
installed on certain airplanes. We are issuing 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: This AD becomes effective on September 29, 2010.
    On September 29, 2010, the Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion

    On May 14, 2010, 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 serial number starter generators where deficient 
armature insulating materials may have been installed on Hawker 
Beechcraft Corporation Model 390 airplanes. This proposal was published 
in the Federal Register as a notice of proposed rulemaking (NPRM) on 
May 21, 2010 (FR 75 28506). The NPRM proposed to detect and replace 
starter generators with deficient armature insulating materials. This 
condition could result in the loss of operation of one or both starter

[[Page 52236]]

generators with consequent loss of all non battery electrical power.

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 affects 213 airplanes in the U.S. 
registry.
    We estimate the following costs to do the inspection:

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

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of airplanes that may need this 
replacement:

------------------------------------------------------------------------
                                                              Total cost
             Labor cost                    Parts cost            per
                                                               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 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-2010-0523; Directorate Identifier 2010-CE-018-AD'' in your 
request.
