Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2017-0045, dated March 9, 2017 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states: During a post flight inspection of a right hand (RH) elevator assembly, disbonding was detected on the upper and lower metal skin from the honeycomb core. Subsequent investigation identified that a manufacturing deficiency caused the detected disbonding and that other flight control surfaces could potentially be affected by the same deficiency. This condition, if not detected and corrected, could reduce the structural stiffness of the flight control surface and downgrade its aerodynamic characteristics, possibly resulting in reduced control of the aeroplane. To address this potential unsafe condition, Piaggio Aero Industries (PAI) issued Service Bulletin (SB) 80-0455 to provide inspection instructions. For the reasons described above, this [EASA] AD requires repetitive inspections of the affected flight control assemblies and, depending on findings, repair or replacement. This [EASA] 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 Docket No. FAA-2017- 0648. Related Service Information Under 1 CFR Part 51 Piaggio Aero Industries S.p.A has issued Piaggio Aero Industries S.p.A. Mandatory Service Bulletin N.: 80-0455, dated: January 13, 2017. The service information describes procedures for repetitive inspections to verify the structural integrity of the flight control assemblies. 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 103 products of U.S. registry. We also estimate that it will take 9 work-hours per product to comply with the basic requirements of the 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 $78,795, or $765 per product. The scope of damage found in the required inspections could vary significantly from airplane to airplane. We have no way of determining how much damage may be found on each airplane or the cost to repair damaged parts on each airplane. In addition, we have no way of knowing how many products may need replacement as a result of the required inspections. The following cost estimates were obtained directly from the manufacturer and we estimate that any necessary follow-on replacement actions would cost as follows: (i) Control surface repair: 10 work-hours for a cost of $850 per product. (ii) Left Hand (LH) Forward Wing Flap Replacement: 4 work-hours and require parts costing $30,079, for a total cost of $30,419. (iii) Right Hand (RH) Forward Wing Flap Replacement: 4 work-hours and require parts costing $30,079, for a total cost of $30,419. (iv) LH Aileron Assembly: 7 work-hours and require parts costing $40,715, for a total cost of $41,310. (v) RH Aileron Assembly: 7 work-hours and require parts costing $86,050, for a total cost of $86,645. (vi) Main Wing LH Inboard Flap Assembly: 4 work-hours and require parts costing $22,699, for a total cost of $23,039. (vii) Main Wing RH Inboard Flap Assembly: 4 work-hours and require parts costing $22,699, for a total cost of $23,039. (viii) LH Elevator Assembly: 8 work-hours and require parts costing $59,917, for a total cost of $60,597. (ix) RH Elevator Assembly: 8 work-hours and require parts costing $59,917, for a total cost of $60,597. There is an additional 10 work-hours that may be required for post- repair or post-installation replacment of flight control surface adjustments and testing, for a total cost of $850. 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. 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, [[Page 29447]] 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-2017-0648; Directorate Identifier 2017-CE-012-AD. (a) Comments Due Date We must receive comments by August 14, 2017. (b) Affected ADs None. (c) Applicability This AD applies to Piaggio Aero Industries S.p.A.
