ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above that will supersede an existing AD. This
emergency AD was sent previously to all known U.S. owners and operators
of PIAGGIO AERO INDUSTRIES S.p.A (Piaggio) Model PIAGGIO P-180
airplanes. This AD results from mandatory continuing airworthiness
information (MCAI) issued by the aviation authority of another country
to identify and correct an unsafe condition on an aviation product. The
MCAI describes the unsafe condition as:
Prompted by reports of water accumulated in the lower part of
the fuselage on a number of Piaggio Model P.180 aeroplanes, which
resulted in jamming of the flight controls, on 17 December 2010, the
Federal Aviation Administration (FAA), the authority of the State of
Registry of the affected aeroplanes, issued Emergency AD 2011-01-51
to require an immediate functional test of the fuselage drain holes
and a report of the results to the FAA. That AD was later
superseded, on 20 December 2010, by FAA Emergency AD 2011-01-53.
This condition, if not detected and corrected, could, when the
aeroplane reaches and holds an altitude where the temperature is
below the freezing point, cause the flight controls to freeze and
jam, possibly resulting in loss of control of the aeroplane.
Since these AD actions were taken, Piaggio Aero Industries, the
type design approval holder and manufacturer of these aeroplanes,
have published Alert Service Bulletin (SB) 80-0324, which describes
the same inspection, testing and correction instructions as
contained in the FAA Emergency AD. EASA AD 2010-0269-E required the
inspection and functional testing of the fuselage drain holes,
corrective actions depending on findings, and reporting of the
findings to Piaggio Aero Industries.
Following issuance of EASA AD, another event of in-flight
blockage of flight controls was reported by an operator. The
aeroplane was already compliant with EASA AD 2010-0269-E, and during
accomplishment of the AD required inspection no discrepancies had
been noted, nor water or ice accumulation were reported. As a
consequence, additional drain holes were not drilled.
This AD requires actions that are intended to address the unsafe
condition described in the MCAI.
DATES: This AD is effective May 31, 2011 to all persons except those
persons to whom it was made immediately effective by Emergency AD 2011-
09-51, issued on April 26, 2011, which contained the requirements of
this amendment.
On May 31, 2011, the Director of the Federal Register approved the
incorporation by reference of certain publications listed in this AD.
We must receive comments on this AD by June 27, 2011.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA received information on two incidents where Piaggio Model
P-180 airplanes had water accumulation in the belly of the fuselage
that froze and caused the flight controls to jam. On December 20, 2010,
we issued Emergency AD 2011-01-53, amendment 39-16582 (76 FR 4056,
January 24, 2011) to require an immediate functional test of the
fuselage drain holes and a report of the results to the FAA. It also
allows, with noted exceptions, for the return/position of the airplane
to a home base, hangar, maintenance facility, etc.
Since we issued AD 2011-01-53, another Piaggio P-180 airplane
experienced jamming of the flight control cables also due to water
accumulating and freezing in the lower fuselage area. This event
happened after this airplane had complied with AD 2011-01-53, noting no
problems with the fuselage drain system.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No.: 2011-0074-E, dated April 22, 2011 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
* * * another event of in-flight blockage of flight controls was
reported by an operator. The aeroplane was already compliant with
EASA AD 2010-0269-E, and during accomplishment of the AD required
inspection no discrepancies had been noted, nor water or ice
accumulation were reported. As a consequence, additional drain holes
were not drilled.
For the reasons described above, this AD, which supersedes EASA
AD 2010-0269-E, requires, in order to improve efficiency of the
drainage system, to cut the rubber flap of the 2 aft flapper valves,
to inspect the flapper valves for proper functioning and the
subsequent accomplishment of a functional test of the fuselage drain
holes.
Furthermore, for those MSN not compliant with Piaggio Aero
Industries Service Bulletin (SB) 80-0291 and where no additional
drain holes had been drilled in accordance with the accomplishment
instructions of Piaggio Aero Industries Alert Service Bulletin ASB-
80-0324, step 5, this AD requires drilling additional drain holes.
It is finally required to report the inspection results to
Piaggio Aero industries.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
PIAGGIO AERO INDUSTRIES S.p.A has issued Service Bulletin
(Mandatory) N.: 80-0330, dated April 21, 2011. The actions described in
this service information are intended to correct the unsafe condition
identified in the MCAI.
FAA's Determination and Requirements of the AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are issuing this
[[Page 27874]]
AD because we evaluated all information provided by the State of Design
Authority and determined the unsafe condition exists and is likely to
exist or develop on other products of the same type design.
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 have also required different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
described in a separate paragraph of the AD. These requirements take
precedence over those copied from the MCAI.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because water
may accumulate in the belly of the fuselage and freeze, which may cause
the flight controls to jam. This condition may lead to loss of control.
Therefore, we determined that notice and opportunity for public comment
before issuing this AD are impracticable and that good cause exists for
making this amendment effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2011-0468; Directorate
Identifier 2011-CE-013-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD will affect 102 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 AD. The average labor rate
is $85 per work-hour.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $78,030, or $765 per product.
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 that 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.

drainage system, to cut the rubber flap of the 2 aft flapper valves,
to inspect the flapper valves for proper functioning and the
subsequent accomplishment of a functional test of the fuselage drain
holes.
Furthermore, for those MSN not compliant with Piaggio Aero
Industries Service Bulletin (SB) 80-0291 and where no additional
drain holes had been drilled in accordance with the accomplishment
instructions of Piaggio Aero Industries Alert Service Bulletin ASB-
80-0324, step 5, this AD requires drilling additional drain holes.
It is finally required to report the inspection results to
Piaggio Aero industries.
