Airworthiness Directives; Hawker Beechcraft Corporation (Type 
Certificate Previously Held by Raytheon Aircraft Company) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Hawker Beechcraft Corporation (Type Certificate Previously Held by 
Raytheon Aircraft Company) Model BAe.125 Series 800A (including C-29A 
and U-125), and 800B airplanes; and Model Hawker 800 (including variant 
U-125A) and 800XP airplanes modified in accordance with a certain 
winglet supplemental type certificate. This AD requires revising the 
Limitations section of the airplane flight manual (AFM) and installing 
placards on the instrument panel. This AD was prompted by reports of 
several instances of severe vibration and wing/aileron oscillations. We 
are issuing this AD to prevent vibration and wing/aileron oscillations, 
which could cause structural damage or lead to divergent flutter, and 
result in loss of integrity of the wing, loss of control of the 
airplane, and in-flight breakup.

DATES: This AD is effective July 2, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of July 2, 2013.
    We must receive comments on this AD by August 1, 2013.

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: 

Discussion

    We have received reports of several instances of severe vibration 
and wing/aileron oscillation due to lack of sufficient flutter margin 
with winglets installed. This condition, if not corrected, could cause 
structural damage or lead to divergent flutter, and result in loss of 
integrity of the wing, loss of control of the airplane, and in-flight 
breakup.

Relevant Service Information

    We reviewed Aviation Partners Service Bulletin SBH-13-001, Revision 
A, dated May 3, 2013. The service information describes procedures for 
revising the Limitations section of the AFM to include an altitude 
restriction, and installing placards on the instrument panel.

FAA's Determination

    We are issuing 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.

[[Page 36090]]

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

Interim Action

    We consider this AD interim action. Aviation Partners Inc. is 
currently developing a modification that will address the unsafe 
condition identified in this AD. Once this modification is developed, 
approved, and available, we may consider additional rulemaking. The 
modification is expected to remove the altitude restriction.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
severe vibration and wing/aileron oscillations could cause structural 
damage or lead to divergent flutter, and result in loss of integrity of 
the wing, loss of control of the airplane, and in-flight breakup. 
Therefore, we find that notice and opportunity for prior public comment 
are impracticable and that good cause exists for making this amendment 
effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2013-0462 and 
Directorate Identifier 2013-NM-092-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
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 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 102 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

    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 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.
