14 CFR Part 39

Airworthiness Directives; Piaggio Aero Industries S.p.A. Model 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:

We are issuing this AD to require actions to correct the unsafe
condition on these products.

DATES: This AD becomes effective January 7, 2008.
On January 7, 2008 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 October 12, 2007 (72
FR 58028). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:

One P 180 aircraft experienced a jamming of its longitudinal
flight control cables. Investigations revealed that its fuselage
drain holes were plugged, and water was trapped in the lower
fuselage.
As a consequence of plugged drain holes, water can accumulate
and freeze when the aircraft reaches and holds altitudes where
temperature is below the freezing point. If not corrected this may
cause the loss of control of the airplane.
The aim of this Airworthiness Directive (AD) is to check for
proper operation, fuselage drain holes and the passenger evaporator
drain line and to introduce a temporary revision of the Aircraft
Maintenance Manual (AMM).

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 AD will affect 60 products of U.S. registry.
We also estimate that it will take about 5 work-hours per product to
comply with basic requirements of this AD. The average labor rate is
$80 per work-hour.
Based on these figures, we estimate the cost of this AD to the U.S.
operators to be $24,000 or $400 per product.
In addition, we estimate that any necessary follow-on actions would
take about 13 work-hours and require parts costing $125, for a cost of
$1,165 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 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.

Reason

(e) The mandatory continuing airworthiness information (MCAI)
