Federal Aviation Administration (FAA), DOT.
Final rule; request for comments.
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.
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.
You may send comments by any of the following methods:

End Further Info
Start Supplemental Information
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 Start Printed Page 42418to 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.
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.
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.

This AD was prompted by 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 ensure the structural integrity of the airplane.
