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 Models 58 and G58 airplanes. This 
proposed AD was prompted by installation of oversized clamps on fuel 
vapor return and/or fuel vent lines in the outboard sections of the 
left and right wings. This proposed AD would require inspecting for 
oversized or deformed fuel hose clamps and replacing as necessary. We 
are proposing this AD to correct the unsafe condition on these 
products.

DATES: We must receive comments on this proposed AD by April 16, 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-12-0218; 
Directorate Identifier 2012-CE-003-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

Discussion

    We received reports of installation of oversized clamps on fuel 
vapor return and/or fuel vent lines in the outboard sections of the 
left and right wings on Hawker Beechcraft Corporation Models 58 and G58 
airplanes. This condition, if not corrected, could result in leakage of 
fuel or vapor in areas where electrical wiring and other potential 
ignition sources are present, which could lead to an inflight fire.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin No. SB 28-
4039, Revision 1, dated October 2011. The service bulletin describes 
procedures for inspecting for oversized or deformed fuel hose clamps 
and replacing as necessary.

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 244 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
----------------------------------------------------------------------------------------------------------------
Defueling, inspection of the      3.5 work-hours x $85 per  Not applicable....         $297.50          $72,590
 fuel hose clamps, and refueling.  hour = $297.50.
----------------------------------------------------------------------------------------------------------------

    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 aircraft that might need 
these replacements:

[[Page 12758]]



                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                  Action                                Labor cost                 Parts cost        product
----------------------------------------------------------------------------------------------------------------
Replacement of fuel hose clamps (Cost       3 work-hours x $85 per hour = $255             $20             $275
 represents replacement of a maximum of 20
 clamps depending on airplane
 configuration).
----------------------------------------------------------------------------------------------------------------


    Note: 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.
