Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A. 
Airplanes

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

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for PIAGGIO 
AERO INDUSTRIES S.p.A. Model P-180 airplanes. This 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 disbonding of the upper and lower metal skin from the 
honeycomb core on the elevator assembly and other flight control 
surfaces. We are issuing this AD to require actions to address the 
unsafe condition on these products.

DATES: This AD is effective November 16, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 16, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain PIAGGIO AERO 
INDUSTRIES S.p.A. Model P-180 airplanes. The NPRM was published in the 
Federal Register on June 29, 2017 (82 FR 29445). The NPRM proposed to 
correct an unsafe condition for the specified products and was based on 
mandatory continuing airworthiness information (MCAI) originated by an 
aviation authority of another country. 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.

    The MCAI can be found in the AD docket on the Internet at https://www.regulations.gov/document?D=FAA-2017-064-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed PIAGGIO AERO INDUSTRIES S.p.A. Mandatory Service 
Bulletin N.: 80-0455, dated: January 13, 2017. This 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 AD.

Costs of Compliance

    We estimate that this 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 this AD. The average labor rate is $85 
per work-hour.
    Based on these figures, we estimate the cost of this 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

[[Page 47372]]

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 replacement 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to small airplanes and domestic 
business jet transport airplanes to the Director of the Policy and 
Innovation Division.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will 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 AD:
    (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.

    Unless already done, do the actions in paragraphs (f)(1) through 
(8) of this AD. The parts affected by this AD are all left hand (LH) 
forward flaps, right hand (RH) forward flaps, main wing LH inboard 
flaps, main wing RH inboard flaps, LH ailerons, RH ailerons, LH 
elevators, and RH elevators, hereafter referred to as ``affected 
control surface'' in this AD.
    (1) Within the next 50 hours time-in-service (TIS) after 
November 16, 2017 (the effective date of this AD) or within the next 
200 hours TIS after the last coin tapping inspection of the affected 
control surface following PAI Non-Destructive Test Manual (NDTM) 
180-MAN-0300-01107, Chapter 51-00-01; whichever occurs later, do a 
coin tapping inspection of each affected control surface. 
Repetitively thereafter inspect at the intervals specified in 
paragraphs (f)(3)(i) and (ii). Follow Part B of the Accomplishment 
Instructions in PAI SB No. 80-0455.

Instructions in PAI SB No. 80-0455.
    (5) Repair of an affected control surface, as required by 
paragraph (f)(2) or (4) of this AD, does not constitute terminating 
action for repetitive inspections as required by this AD

[[Page 47373]]

for that affected control surface, unless the FAA-approved repair 
instructions specify otherwise.
    (6) Replacement of the affected part on an airplane with a part 
listed in table 1 of PAI SB No. 80-0455, constitutes terminating 
action for the repetitive inspections required by this AD for that 
part.
    (7) You may incorporate the actions of PAI SB No. 80-0455, into 
your FAA-approved airplane inspection program (AIP) or maintenance 
program (instructions for continued airworthiness) to ensure the 
continuing airworthiness of each operated airplane.
    (8) After November 16, 2017 (the effective date of this AD), you 
may install on an airplane an affected control surface not listed in 
table 1 of PAI SB No. 80-0455, provided that before further flight 
after installation, the affected control surface has been inspected 
as specified in this AD and found airworthy.
