Airworthiness Directives; Piaggio Aero Industries S.p.A Airplanes

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 certain 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 insufficient clearance between one of the horizontal stabilizer end ribs and the corresponding elevator horn. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2013-0239, dated September 30, 2013 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:

Insufficient clearance between one of the horizontal stabilizer end rib and the corresponding elevator horn was found on an in-

service aeroplane.

This condition, if not detected and corrected, could lead to interference between the elevator and horizontal stabilizer surfaces, resulting in restricted elevator control and consequent reduced control of the aeroplane.

To address this potential unsafe condition, Piaggio Aero Industries (PAI) issued Service

Page 69601

Bulletin (SB) 80-0381 to provide inspection instructions.

For the reasons described above, this AD requires accomplishment of a one-time measurement of the actual clearance between the elevator horn and the horizontal stabilizer tip rib, and depending on findings, restoration of the required minimum clearance value. This AD also requires reporting of the inspection result to PAI.

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-2013-0964.

Relevant Service Information

Piaggio Aero Industries S.p.A. has issued Mandatory Service Bulletin No.: 80-0381, Rev. 0, dated May 2, 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 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 would affect 112 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 this proposed AD on U.S. operators to be $9,520, or $85 per product.

In addition, we estimate that any necessary follow-on actions would take about 5 work-hours and require parts costing $50, for a cost of $475 per product. We have no way of determining the number of products that may need these actions.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-

0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information Collection Clearance Officer, AES-200.

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 proposed 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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 Amended

0

2. The FAA amends Sec. 39.13 by adding the following new AD:

Piaggio Aero Industries S.p.A: Docket No. FAA-2013-0964; Directorate Identifier 2013-CE-035-AD.

(a) Comments Due Date

We must receive comments by January 6, 2014.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Piaggio Aero Industries S.p.A Model P-180 airplanes, manufacturer serial numbers 1002 and 1004 through 1231, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 27: Flight Controls.

(e) Reason

This AD was prompted by 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 insufficient clearance between one of the horizontal stabilizer end ribs and the corresponding elevator horn. We are issuing this proposed AD to detect and correct insufficient clearance between one of the horizontal stabilizer end rib and the corresponding elevator horn, which could result in interference between the elevator and horizontal stabilizer surfaces, consequently resulting in restricted elevator control and reduced control of the airplane.

(f) Actions and Compliance

Unless already done, do the following actions as specified in paragraphs (f)(1) through (f)(3) of this AD:

(1) Within 200 hours time-in service (TIS) after the effective date of this AD or 12 months after the effective date of this AD, whichever occurs first, measure the clearances between the horns of the elevator and the end ribs of the horizontal stabilizer (HS) on left-hand (LH) and right-hand (RH) sides following Part A of the Accomplishment Instructions section of

Page 69602

Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No.: 80-

0381, Rev. 0, dated May 2, 2013.

(2) If the clearance is less than 5 mm on HS LH or RH side during the measurement as required by paragraph (f)(1) of this AD, before further flight, rework the affected elevator to restore the required minimum clearance between the horn of the elevator and the end rib of the horizontal stabilizer following Part B of the Accomplishment Instructions section of Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No.: 80-0381, Rev. 0, dated May 2, 2013.

(3) Within 30 days after accomplishment of the measurement as required by paragraph (f)(1) of this AD, report the results to Piaggio Aero Industries S.p.A. following Part C of the Accomplishment Instructions section of Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No.: 80-0381, Rev. 0, dated May 2, 2013.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Mike Kiesov, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4144; fax: (816) 329-4090; email: mike.kiesov@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved.
