Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Pilatus Aircraft Ltd. Model PC-6/B2-H4 airplanes. This AD results from 
mandatory continuing airworthiness information (MCAI) issued by the 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as faulty rivets installed in the airframes during production 
could reduce the structural integrity of the airplane. We are issuing 
this AD to require actions to address the unsafe condition on these 
products.

DATES: This AD is effective August 5, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of August 5, 
2013.
    We must receive comments on this AD by August 30, 2013.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2013-0115-E, dated May 28, 2013 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

Reports have been received that rivets with insufficient shear 
(about 50% shear allowable) were delivered from the supplier

[[Page 42418]]

to Pilatus. Investigations revealed that the faulty rivets were 
already installed in various airframes and spare parts during the 
production process.

This condition, if not corrected, could result in a reduced strength 
of the aeroplane structure.

For the reasons described above, this AD prohibits all flight 
operations for the affected aeroplanes, except for a ferry flight 
under limited flight conditions to a repair station. In order to 
resume flights, this AD requires accomplishment of an inspection 
and, depending on findings, a repair of all affected areas of the 
aeroplane.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Pilatus Aircraft Ltd. has issued Technical Memo TM-06-000004, Issue 
01, dated May 16, 2013. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of the 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 issuing this AD because we 
evaluated all information provided by the State of Design Authority and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design.

FAA's 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 there 
are no airplanes currently on the U.S. registry and thus, does not have 
any impact upon the public. Therefore, we find that notice and 
opportunity for prior public comment are unnecessary 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 we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2013-0598; Directorate 
Identifier 2013-CE-015-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 will affect 0 products of U.S. registry at 
this time. We also estimate that it will take about 5 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $85 per work-hour. Required parts will cost about $1,000 
per product.
    Based on these figures, we estimate there to be no cost for U.S. 
operators for this AD. However, if an airplane affected by this AD is 
at any time placed on the U.S. registry, it will cost approximately 
$1,425 per product to comply with this AD.
    According to the manufacturer, some of the costs of this 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 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),
    (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.

specified in paragraph (j)(3) of this AD to obtain FAA-approved 
inspection procedures approved specifically for compliance with this 
AD for inspecting the airplane for loose rivets and for places where 
rivets are missing, and do the inspection.
    (2) If any rivet deficiencies are found during the inspection 
required in paragraph (f)(1) of this AD, before further fight, 
contact PILATUS Aircraft Ltd. at the address specified in paragraph 
(j)(3) of this AD to obtain an FAA-approved repair scheme approved 
specifically for compliance with this AD and incorporate the repair.
