14 CFR Part 39

[Docket No. FAA-2015-2466; Directorate Identifier 2015-CE-018-AD; 
Amendment 39-18273; AD 2015-19-11]

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) issued 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 AD to require actions to address the 
unsafe condition on these products.

DATES: This AD is effective November 3, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publication listed in the AD as of November 3, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add 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 July 6, 2015 (80 FR 38406). 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:

    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.

    The MCAI can be found in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-2466-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 38406, July 6, 
2015) 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 the 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 (80 FR 38406, July 6, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 38406, July 6, 2015).

Related Service Information Under 1 CFR Part 51

    We reviewed 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 identified in the 
ADDRESSES section of the AD.

Costs of Compliance

    We estimate that this AD will affect 28 products of U.S. registry. 
We also estimate that it will take about 1 work-hour 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 $2,380, or $85 per product.
    In addition, we estimate that any necessary follow-on actions will 
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 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 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.

Aero Industries at the address specified in paragraph (i)(3) of this 
AD for an FAA-approved repair scheme, approved specifically for this 
AD, and incorporate that repair.
