Federal Aviation Administration (FAA), Department of Transportation (DOT).
Notice of proposed rulemaking (NPRM).
We propose to adopt a new airworthiness directive (AD) for PILATUS AIRCRAFT LTD. Model PC-12, PC-12/45, 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 a malfunction of the universal joint. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
We must receive comments on this proposed AD by August 28, 2015.
You may send comments by any of the following methods:

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2015-0111, dated June 16, 2015 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:
A case of malfunctioning was reported of a universal joint installed between the control tube assembly and the control column on a PC-12/47E aeroplane.
Investigation determined that the malfunction was caused by an incorrectly manufactured universal joint. Universal joints from the same manufacturing batch were provided to operators between 01 March 2014 and 28 February 2015, and are thus potentially affected.
This condition, if not corrected, could lead to other cases of malfunctioning of a universal joint, possibly resulting in reduced control of the aeroplane.
To address this potential unsafe condition, Pilatus Aircraft Ltd. issued Service Bulletin (SB) No. 27-022 to provide instructions for replacement of the universal joints in the flight controls.
For the reason described above, this AD requires removal from service of the potentially incorrectly manufactured universal joints.
You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-2775.
Related Service Information Under 1 CFR Part 51
Pilatus Aircraft Limited has issued PILATUS PC-12 Service Bulletin No: 27-022, dated March 17, 2015. The PILATUS PC-12 Service Bulletin No: 27-022, dated March 17, 2015, describes procedures for replacement of the universal joint on the aileron control system. 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 55 products of U.S. registry. We also estimate that it would take about 3 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 $69,025 or $1,255 per product.
According to the manufacturer, all 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.
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, andStart Printed Page 40951
(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.Start List of Subjects

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 a malfunction of the universal joint. We are issuing this proposed AD to replace defective aileron control system universal joints.
(f) Actions and Compliance
Unless already done, do the following actions in paragraphs (f)(1) through (f)(2) of this AD:
(1) For airplanes equipped with aileron control system universal joints part number (P/N) 944.61.73.012 or P/N 5220.127.116.11, purchased between March 1, 2014, and February 28, 2015; or universal joints installed in service through an aileron control system inspection kit P/N 500.50.12.314, purchased between March 1, 2014, and February 28, 2015, do one of the following actions as applicable:
(i) For airplanes with less than 200 flight cycles since first flight of the airplane or less than 200 flight cycles since installation of an affected universal joint or inspection kit, whichever applies: Within 10 flight cycles after the effective date of this AD or 3 months after the effective date of this AD, whichever occurs first, replace with a new universal joint P/N 518.104.22.168 purchased after March 1, 2015, and marked with a placard “RT iO” following the Accomplishment Instructions in PILATUS PC-12 Service Bulletin No: 27-022, dated March 17, 2015.
