We propose to adopt a new airworthiness directive (AD) for Pilatus Aircraft Ltd. Model PC-12/47 and PC-12/47E airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the aileron trim tab disconnecting above 10,000 feet altitude. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2015-0060, dated April 10, 2015 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:


[[Page 24855]]


    During a continued airworthiness review, a potential unsafe 
condition was identified that could result from a disconnected 
aileron trim tab occurring above an altitude of 10.000 feet.
    This condition, if not corrected, could lead, in case of a 
disconnection of an aileron trim tab, to undamped aeroplane 
vibrations, potentially resulting in structural failure.
    To address this potential unsafe condition, Pilatus Aircraft 
Ltd. issued SB No. 27-021 to provide instructions for replacement of 
the aileron tab counter balance weight.
    For the reason described above, this AD requires replacement of 
the aileron tab counter balance weight with a new, slightly heavier, 
aileron tab counter balance weight.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2015-1177.

Related Service Information Under 1 CFR Part 51

    Pilatus Aircraft Ltd. has issued PILATUS PC-12 Service Bulletin No: 
27-021, dated January 20, 2015. The PILATUS PC-12 Service Bulletin No: 
27-021, dated January 20, 2015, describes procedures to replace the 
aileron tab counter balance weight. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed AD will affect 303 products of U.S. 
registry. We also estimate that it would take about 5.5 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $1,000 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $444,652.50, or $1,467.50 per product.
    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.
