ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
Piaggio Aero Industries S.p.A. Model P–
180 Airplanes. This proposed AD
results from mandatory continuing
airworthiness information (MCAI)
originated 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 insufficient sealing of a
steering select/bypass valve installed in
the nose landing gear (NLG) manifold.
The FAA is proposing this AD to require
actions that address the unsafe
condition on these products.
DATES: The FAA must receive comments
on this proposed AD by July 22, 2019.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD No.
2017–0229, dated November 21, 2017
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for Piaggio
Aero Industries S.p.A. Model P–180
airplanes. The MCAI states:
Other Related Service Information
An occurrence was reported of finding
insufficient sealing of a Steering Select/
Bypass Valve installed on the nose landing
gear (NLG) Steering Manifold of a P.180
aeroplane.
This condition, if not detected and
corrected, could lead to uncommanded
deflection of the NLG wheel, possibly
resulting in reduced control of the aeroplane
on the ground, with consequent damage to
the aeroplane and injury to occupants.
To address this potential unsafe condition,
PAI issued Service Bulletin (SB) 80–0325 to
provide inspection and rectification
instructions.
For the reason described above, this
[EASA] AD requires a leak test of the NLG
Steering Manifold and, depending on the
finding(s), accomplishment of applicable
corrective action(s). This [EASA] AD also
requires amendment of the applicable
Aircraft Flight Manual (AFM).

The MCAI further notes that airplanes
with NLG steering manifold part
number 72608 installed are known to
include manufacturing serial numbers
1001, 3001, 3003, 3004, 3006, 3007, and
3008, and also include airplanes that
have incorporated Piaggio Aerospace

FAA’s Determination and Requirements
of the Proposed 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. The FAA is proposing
this AD because the FAA evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Costs of Compliance
The FAA estimates that this proposed
AD will affect 130 products of U.S.
registry. The FAA also estimates that it
would take about 2.5 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, the FAA
estimates the cost of the proposed AD
on U.S. operators to be $27,625, or
$212.50 per product.
If necessary, the FAA estimates that
replacing a NLG steering manifold
would take about 10 work-hours and
require parts costing $50,058, for a cost
of $50,908 per product. The FAA has 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.
The FAA is 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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to small airplanes, gliders,
balloons, airships, domestic business jet
transport airplanes, and associated
appliances to the Director of the Policy
and Innovation Division.
Regulatory Findings
The FAA determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Will not affect intrastate aviation
in Alaska, 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.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD No. 2017-0229, dated November 21, 2017 (referred to after this as
``the MCAI''), to correct an unsafe condition for Piaggio Aero
Industries S.p.A. Model P-180 airplanes. The MCAI states:
An occurrence was reported of finding insufficient sealing of a
Steering Select/Bypass Valve installed on the nose landing gear
(NLG) Steering Manifold of a P.180 aeroplane.
This condition, if not detected and corrected, could lead to
uncommanded deflection of the NLG wheel, possibly resulting in
reduced control of the aeroplane on the ground, with consequent
damage to the aeroplane and injury to occupants.
To address this potential unsafe condition, PAI issued Service
Bulletin (SB) 80-0325 to provide inspection and rectification
instructions.
For the reason described above, this [EASA] AD requires a leak
test of the NLG Steering Manifold and, depending on the finding(s),
accomplishment of applicable corrective action(s). This [EASA] AD
also requires amendment of the applicable Aircraft Flight Manual
(AFM).
The MCAI further notes that airplanes with NLG steering manifold
part number 72608 installed are known to include manufacturing serial
numbers 1001, 3001, 3003, 3004, 3006, 3007, and 3008, and also include
airplanes that have incorporated Piaggio Aerospace Service Bulletin No.
80-0425, Revision 0, dated March 30, 2017, and Piaggio Aerospace
Service Bulletin No. 80-0454, Revision 0, March 6, 2017. You may

FAA's Determination and Requirements of the Proposed 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. The FAA is proposing this AD
because the FAA evaluated all information and determined the unsafe
condition exists and is likely to exist or develop on other products of
the same type design.
Costs of Compliance
The FAA estimates that this proposed AD will affect 130 products of
U.S. registry. The FAA also estimates that it would take about 2.5
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, the FAA estimates the cost of the proposed
AD on U.S. operators to be $27,625, or $212.50 per product.
If necessary, the FAA estimates that replacing a NLG steering
manifold would take about 10 work-hours and require parts costing
$50,058, for a cost of $50,908 per product. The FAA has 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.
The FAA is 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to small airplanes, gliders,
balloons, airships, domestic business jet transport airplanes, and
associated appliances to the Director of the Policy and Innovation
Division.
Regulatory Findings
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, 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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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 airworthiness
directive (AD):
Piaggio Aero Industries S.p.A.: Docket No. FAA-2019-0412; Product
Identifier 2018-CE-030-AD.
(a) Comments Due Date
The FAA must receive comments by July 22, 2019.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Piaggio Aero Industries S.p.A. Model P-180
airplanes, certificated in any category.
(d) Subject
Air Transport Association of America (ATA) Code 32: Landing
Gear.
(e) Reason
This AD was prompted by mandatory continuing airworthiness
information (MCAI) originated 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 insufficient
sealing of a steering select/bypass valve installed in the nose
landing gear (NLG) manifold. The FAA is issuing this AD to detect
and correct insufficient sealing of the steering select/bypass valve
in the NLG steering manifold, which could lead to un-commanded NLG
wheel turns with consequent lateral runway departure.
(f) Actions and Compliance
Unless already done, do the following actions in paragraphs
(f)(1) through (3) of this AD.
(1) For airplanes with NLG steering manifold part number (P/N)
72608 installed: (i) Within 50 hours time-in service after the
effective date of this AD, do a steering manifold pressure leakage
test and, if there is steering actuator movement during the test,
replace the NLG steering manifold and repeat the test by following
the Accomplishment Instructions, procedure steps (1) through (24),
in Piaggio Aerospace Service Bulletin No. 80-0325, Revision 0, dated
August 10, 2017.
(ii) If steering actuator movement occurs during procedure step
(9) or procedure step (15) of the leakage test required in paragraph
(f)(1)(i) of this AD, replacing the NLG steering manifold and
repeating the steering manifold pressure leakage test is required
before further flight.
(2) For all airplanes, after the effective date of this AD, do
not install NLG steering manifold P/N 72608 on any airplane unless
it has been inspected as specified in paragraph (f)(1) of this AD
and no steering actuator movement occurred.
(3) For all airplanes, within 30 days after the effective date
of this AD, revise the airplane flight manual (AFM) by replacing
certain pages in the Emergency Procedures section of the AFM by
following the Instructions in Piaggio Aerospace P.180 AVANTI II/EVO
Temporary Change No. 89, dated August 30, 2017.
