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 failure of engine oil dipsticks, installed on
Pratt & Whitney Canada (P&WC) PT6A66 and PT6A66B engines, were
detected on P.180 aeroplanes; such failures, due to moisture
penetration into the dipstick and subsequent corrosion, can cause
incorrect reading of the engine oil low level on the Refuel/Ground
Test Panel.
If left uncorrected, this situation could lead to in-flight engine
failure(s). We are issuing this AD to require actions to correct the
unsafe condition on these products.
DATES: This AD becomes effective November 18, 2010.
On November 18, 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 July 23, 2010 (75 FR
43095). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Some cases of failure of engine oil dipsticks, installed on
Pratt & Whitney Canada (P&WC) PT6A66 and PT6A66B engines, were
detected on P.180 aeroplanes; such failures, due to moisture
penetration into the dipstick and subsequent corrosion, can cause
incorrect reading of the engine oil low level on the Refuel/Ground
Test Panel.
If left uncorrected, this situation could lead to in-flight engine
failure(s).
This AD requires:
(1) Repetitive visual checks of the engine oil levels to prevent an
undetected low level condition;
(2) Repetitive inspections of the oil dipsticks to detect faulty
units;
(3) Replacement of faulty oil dipsticks or visual checks of the oil
level at reduced not to exceed intervals, until replacement of faulty
units.
The engine TC Holder is currently developing a modification that
will address the unsafe condition identified in this AD; once such
modification is developed, approved and available, further mandatory
actions might be considered.
This Correction is issued to amend the AD number heading: It was
PAD, it is AD.
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 99 products of U.S. registry.
We also estimate that it will take about 2.5 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 this AD to the U.S.
operators to be $21,038 or $212.50 per product.
In addition, we estimate that any necessary follow-on actions would
take about 1 work-hour and require parts costing $9,000, for a cost of
$9,085 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
[[Page 63061]]
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.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2010-21-08 PIAGGIO AERO INDUSTRIES S.p.A.: Amendment 39-16468;
Docket No. FAA-2010-0737; Directorate Identifier 2010-CE-037-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective November
18, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to PIAGGIO AERO INDUSTRIES S.p.A. Model
PIAGGIO P-180 airplanes, all serial numbers, certificated in any
category.
Subject
(d) Air Transport Association of America (ATA) Code 79: Engine
Oil.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Some cases of failure of engine oil dipsticks, installed on
Pratt & Whitney Canada (P&WC) PT6A66 and PT6A66B engines, were
detected on P.180 aeroplanes; such failures, due to moisture
penetration into the dipstick and subsequent corrosion, can cause
incorrect reading of the engine oil low level on the Refuel/Ground
Test Panel.
If left uncorrected, this situation could lead to in-flight
engine failure(s).
This AD requires:
(1) Repetitive visual checks of the engine oil levels to prevent
an undetected low level condition;
(2) Repetitive inspections of the oil dipsticks to detect faulty
units;
(3) Replacement of faulty oil dipsticks or visual checks of the
oil level at reduced not to exceed intervals, until replacement of
faulty units.
The engine TC Holder is currently developing a modification that
will address the unsafe condition identified in this AD; once such
modification is developed, approved and available, further mandatory
actions might be considered.
This Correction is issued to amend the AD number heading: It was
PAD, it is AD.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within one month after November 18, 2010 (the effective date
of this AD) or within 25 hours time-in-service (TIS) after November
18, 2010 (the effective date of this AD), whichever occurs first,
and repetitively thereafter at intervals not to exceed one month or
25 hours TIS, whichever occurs first, do the following in both
engines:
(i) Visually check the oil level following the Accomplishment
Instructions, Part A, of PIAGGIO AERO INDUSTRIES S.p.A. Service
Bulletin (Mandatory) N.: 80-0287, Rev. N. 1, dated March 24, 2010;
and

following the Accomplishment Instructions, Part B and C, of PIAGGIO
AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N.: 80-0287,
Rev. N. 1, dated March 24, 2010.
(2) If, as determined by the inspection in paragraph (f)(1)(ii)
of this AD, the installed dipsticks are compliant with P&WC Service
Bulletin no. 14383, the repetitive inspections required in paragraph
(f)(1) of this AD may be done at intervals not to exceed one month
or 50 hours TIS, whichever occurs first.
(3) If a failed dipstick is found during any functional check
required in paragraph (f)(1)(ii) of this AD, do one of the
following;
(i) If a replacement dipstick is available, replace it before
further flight; or
(ii) If a replacement dipstick is not available, the failed
dipstick may be reinstalled, but, until replacement, the oil level
check specified in paragraph (f)(1)(i) of this AD must be
repetitively done in the affected engine within 5 hours TIS from the
last check. The repetitive oil level check interval may be extended
to 10 hours TIS based on oil consumption in accordance with the
Accomplishment Instructions, Part B, of PIAGGIO AERO INDUSTRIES
S.p.A. Service Bulletin (Mandatory) N.: 80-0287, Rev. N. 1, dated
March 24, 2010.
(4) Replacement of the oil level dipstick does not terminate the
repetitive check requirements of paragraph (f)(1) of this AD.
