AD 2015-19-11

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.

Final rule.

Adoption of the Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

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 serialnumbers. 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For the reasons described above, this AD retains the requirements of EASA AD 2010-0146, which is superseded, requires inspection and, depending on findings, reinforcement of the pressurized bulkhead structure on extended population of aeroplanes.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.
