AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for Piaggio Aero Industries S.p.A Model P-180 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 need to restore the safe fatigue life of the bulkhead structure. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by August 20, 2015.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2015-0071, dated: April 30, 2015 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

In 1997, Piaggio Aero Industries S.p.A (PAI) developed a modification of the forward pressurized bulkhead, published through PAI Service Bulletin (SB) 80-0081, aiming to restore the safe fatigue life of the bulkhead structure.

Consequently, ENAC Italy (formerly RAI) issued Prescrizione di Aeronavigabilita (PA) 97-148 to require compliance with this SB.

After RAI PA 97-148 was issued, PAI issued SB 80-0081 Revision 2 to provide improved instructions for specific serial numbers. Prompted by this development, EASA issued AD 2010-0146 superseding PA 97-148 and requiring accomplishment of instruction of PAI issued SB 80-0081 Revision 2.

After that AD was issued, PAI issued SB 80-0081 Revision 3 to make the instructions for inspection (and, depending on findings, rework/reinforcement) applicable to all aeroplanes.

For the reasons described above, this AD retains the requirements of EASA AD 2010-0146, which is superseded, requires inspection and, depending on findings, reinforcement of the pressurized bulkhead structure on extended population of aeroplanes. This AD also specifies that certain aeroplanes modified in accordance with SB 80-0081 up to Revision 2 need to be inspected and, depending on findings, reinforced as required by this AD.

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-2466.

Related Service Information Under 1 CFR Part 51

Piaggio Aero Industries S.p.A has issued Piaggio Aero Industries S.p.A. Service Bulletin 80-0081, Revision No. 3, dated: January 20, 2015. The service information describes procedures for inspection and, depending on findings, rework/reinforcement of the bulkhead. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means Start Printed Page 38407identified 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 28 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $2,380, or $85 per product.

In addition, we estimate that any necessary follow-on actions would take about 88 work-hours and require parts costing $30,000, for a cost of $37,480 per product. We have no way of determining the number of products that may need these actions.

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.
