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


Notice of proposed rulemaking (NPRM); rescission.


We propose to rescind an airworthiness directive (AD) for PIAGGIO AERO INDUSTRIES S.p.A. Model P-180 airplanes. The existing AD resulted 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 partial detachment of the inner protective film of the composite nacelles. Since issuance of that AD, we have determined that the unsafe condition does not exist or is not likely to develop on affected type design airplanes, and therefore the AD should be rescinded. The proposed AD would allow the public the opportunity to comment on the FAA's determination of the unsafe condition no longer existing before it is officially rescinded.


We must receive comments on this proposed AD by July 15, 2013.

We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD.

On March 18, 1999, we issued AD 99-07-10, Amendment 39-11095 (64 FR 14824, March 29, 1999). That AD required actions intended to address an unsafe condition on the products listed above.

Since we issued AD 99-07-10, Amendment 39-11095 (64 FR 14824, March 29, 1999), the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD Cancellation Notice No.: 2013-0085-CN, dated April 8, 2013, which cancelled Ente Nazionale per l'Aviazione Civile (ENAC) (the airworthiness authority for Italy) AD No. 98-208, dated June 9, 1998. Italian AD No. 98-208 required the inspections and corrective actions of Piaggio Service Bulletin (Mandatory) No.: SB-80-0101, Original Issue: May 6, 1998. AD 99-07-10, Amendment 39-11095 (64 FR 14824, March 29, 1999), is the result of mandatory continuing airworthiness information (MCAI) issued by ENAC.

We have been notified that since 2000, all nacelles for PIAGGIO AERO INDUSTRIES S.p.A Model P-180 airplanes have been manufactured by a different supplier, and no new occurrences of film detachment have been reported on earlier manufactured airplanes. Therefore, nacelle inner panel protective film detachment is no longer considered probable. Consequently, PIAGGIO AERO INDUSTRIES S.p.A. issued Mandatory Service Bulletin No. SB 80-0101, Rev. N. ZZ, dated February 19, 2013, to cancel the previous revision of this service bulletin.

FAA's Determination and Requirements of the Proposed AD

We are proposing this AD because we evaluated all information and determined the unsafe condition identified in the existing AD no longer exists and the AD is not necessary.

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 Start Printed Page 32364is 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.
