Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2013-0134, dated July 2, 2013 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

During an inspection of a P2006T, a nose landing gear (NLG) lower link was found with two cracks. The affected NLG lower link is part of NLG lower link assembly P/N 26-8-1417-000.

This condition, if not detected and corrected, could lead to NLG failure, possibly resulting in damage to the aeroplane and injury to the occupants.

To address this potential unsafe condition, Costruzioni Aeronautiche Tecnam (hereafter referred to as Tecnam) issued Service Bulletin (SB) SB-128-CS, providing inspection instructions. Tecnam also developed an improved NLG lower link assembly with P/N 26-8-8000-000, which can be installed in service by accomplishment of Tecnam SB-104-CS.

For the reasons described above, this AD requires, for aeroplanes equipped with NLG lower link assembly P/N 26-8-1417-000, a one-time inspection of the NLG lower link and, depending on findings, accomplishment of the applicable corrective action. This AD also requires installation of the improved NLG lower link assembly P/N 26-8-8000-000.

You may obtain further information by examining the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-2013-0888.

Relevant Service Information

Costruzioni Aeronautiche Tecnam srl issued Service Bulletin No. SB 104-CS, Edition 2, Revision 1, dated March 28, 2013 (now superseded); Service Bulletin No. SB 128-CS, Revision 0, dated May 15, 2013; Job Card 442, Revision 1, dated February 11, 2013; Job Card 468, dated October 12, 2012; and Job Card 528, Revision 1, dated April 2, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.Start Printed Page 63908

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 7 products of U.S. registry. We also estimate that it would take about .5 work-hour 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 $0 per product.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $297.50, or $42.50 per product.

In addition, we estimate that any necessary follow-on actions would take about 6 work-hours and require parts costing $1,800, for a cost on U.S. operators of $16,170, or $2,310 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.
