Airworthiness Directives; Piaggio Aero Industries S.p.A. Model
PIAGGIO P-180 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. 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:
Some cases of corrosion were detected in the interface between
the elevator hinges fittings (metallic) and the horizontal
stabilizer (carbon fibre); investigation identified the cause in
galvanic corrosion between dissimilar materials.
If left uncorrected, this situation could lead to a structural
failure of the elevator, which could result in possible loss of
control of the aeroplane.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective December 10, 2010.
On December 10, 2010, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on August 9, 2010 (75
FR 47734). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Some cases of corrosion were detected in the interface between
the elevator hinges fittings (metallic) and the horizontal
stabilizer (carbon fibre); investigation identified the cause in
galvanic corrosion between dissimilar materials.
If left uncorrected, this situation could lead to a structural
failure of the elevator, which could result in possible loss of
control of the aeroplane.
This AD requires:
(1) Inspection of the hinges fittings for corrosion and of the
stabilizer for delamination;
(2) Repair of the stabilizer, if necessary;
(3) Replacement of the fittings, if corroded;
(4) Improvement of fittings installation;
(5) Installation of aluminum strips in the stabilizer to improve
bonding, in accordance with Piaggio Aero Industries (PAI) Service
Bulletin (SB) 80-0262 Revision 2.
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 available data and determined that air safety and
the public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this proposed AD will affect 96 products of U.S.
registry. We also estimate that it would take about 9 work-hours 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 the proposed AD on
U.S. operators to be $73,440, or $765 per product.
In addition, we estimate that any necessary follow-on actions would
take about 32 work-hours and require parts costing $11,000, for a cost
of $13,720 per product. We have no way of determining the number of
products that may need these actions.
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 DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities
[[Page 68173]]
under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD Docket.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.
