Airworthiness Directives; Hawker Beechcraft Corporation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Hawker Beechcraft Corporation Model G58 airplanes. This 
proposed AD was prompted by notification from Hawker Beechcraft 
Corporation that certain affected aircraft were produced with the 
incorrect gauge wiring installed. This proposed AD would require 
replacement of the incorrect gauge wiring with the correct wiring 
required by type design and the aircraft's circuit protection. We are 
proposing this AD to correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by September 24, 
2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2012-0829; 
Directorate Identifier 2012-CE-024-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because 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 about this proposed AD.

Discussion

    We received notification from Hawker Beechcraft Corporation that 
their wiring fabricators created wiring bundles with the incorrect 
gauge wiring for the three-light strobe system of certain Model G58 
airplanes. The wire used is a smaller gauge wire than required by type 
design and the aircraft's circuit protection is not adequate to protect 
the incorrect gauge wire. This condition, if not corrected, could 
result in smoke in the cockpit and the possible failure of the 
aircraft's strobe light system. The failure of the wiring for the 
aircraft's strobe light system could also cause potential damage to 
surrounding wires.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin No. SB 33-
4053, dated February 2011. The service bulletin describes procedures 
for replacing the existing 20-gauge wire with a new wire of 18-gauge 
size, part number (P/N) M27500-18TE1T14, or equivalent.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 40 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Replace supply wire of the three       16 work-hours x $85 per               $50          $1,410         $56,400
 light strobe system.                   hour = $1,360.
----------------------------------------------------------------------------------------------------------------

     According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 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 this 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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
