Abstract
The FAA is adopting a new airworthiness directive (AD) for all Piaggio Aviation S.p.A. (Piaggio) Model P-180 airplanes. This 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 identifies the unsafe condition as accumulation of water and subsequent freezing in the pitot-tube, which results in pitot-tube blockage. This AD requires modifying the total air temperature (TAT) probe heater electrical circuit and revising your existing airplane flight manual (AFM). The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Piaggio Model P-180
airplanes. The NPRM published in the Federal Register on April 11, 2022
(87 FR 21034). The NPRM was prompted by MCAI originated by the European
Union Aviation Safety Agency (EASA), which is the Technical Agent for
the Member States of the European Union. EASA issued EASA AD 2019-0144,
dated June 19, 2019 (referred to after this as ``the MCAI''), to
address an unsafe condition on all Piaggio Model P.180 Avanti and
Avanti II airplanes. The MCAI states:
Occurrences of pitot-tube blockage were reported, leading to in-
flight air data loss. Investigation results indicated that
accumulation of water and subsequent freezing was the failure cause.
This condition, if not corrected, could lead to unreliable
indication or loss of in-flight air data provided by systems
deriving their data from measuring air pressure, possibly resulting
in loss of control of the aeroplane.
To address this potentially unsafe condition, Piaggio issued the
applicable AFM TC [Piaggio Aviation P.180 AVANTI II/EVO Temporary
Change 79, dated September 17, 2018; and Piaggio Aviation P.180
AVANTI Temporary Change No. 36, dated April 11, 2019], providing
instructions to switch on pitot-tube heater before taxi if operation
in heavy rain, snow or icing condition is expected. To prevent
concurrent activation of TAT probe heater on ground, which could
lead to temporary air data indications failure, Piaggio issued the
applicable SBs [Piaggio Aviation Service Bulletin No. 80-0430,
Revision 1; and Piaggio Aero Industries Service Bulletin No. 80-
0457, Original Issue], providing modification instructions to
inhibit on-ground power supply to TAT probe heater, when the pitot-
tube heater is activated.
For the reasons described above, this [EASA] AD requires
amendment of the applicable AFM and, for certain aeroplanes,
modification of the TAT probe heater electrical circuit.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> by
searching for and locating Docket No. FAA-2022-0452.
In the NPRM, the FAA proposed to require modifying the TAT probe
heater electrical circuit and revising your existing AFM. The FAA is
issuing this AD to prevent blockage of the pitot-tube. The unsafe
condition, if not addressed, could result in temporary air data
indications failure, which could result in loss of control of the
airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from Piaggio. The following presents the
comments received on the NPRM and the FAA's response to each comment.
Request To Update Contact Information for Piaggio
Piaggio requested that the FAA revise the NPRM to update the
contact information provided for Piaggio service information.
The FAA agrees and has updated the contact information for Piaggio
throughout this final rule accordingly.
Request Regarding the Background Information
Piaggio requested the FAA remove the extra reference ``and No. 79''
from the quoted MCAI statement in the Background section that reads
``To address this potentially unsafe condition, Piaggio issued the
applicable AFM TC [Piaggio Aviation P.180 AVANTI II/EVO Temporary
Change 79, dated September 17, 2018; and Piaggio
[[Page 58948]]
Aviation P.180 AVANTI Temporary Change No. 36 and No. 79]. . . .''
The FAA agrees and has deleted ``and No. 79'' from the quoted MCAI
statement in the Background section of this AD. Instead, that text has
been replaced with the date of Piaggio Aviation P.180 AVANTI Temporary
Change No. 36, which was originally intended to be provided. This
change does not alter the intent of that language.
Request To Remove Specific Service Bulletin Revision Level
Piaggio requested that paragraphs (g)(2)(ii) and (g)(3)(iii) of the
proposed AD be revised to remove the revision number and date from the
service bulletin reference specified in those paragraphs. Piaggio
explained that this change is necessary because the service bulletin,
independently from the revision, introduces the new Magnaghi landing
gear in lieu of the Safran landing gear.
The FAA partially agrees. The FAA concurs that the referenced
service bulletin up to Revision 2 independent of the revision level
introduces the new Magnaghi landing gear in lieu of the Safran landing
gear. However, the FAA cannot remove the revision level because the FAA
has no way of knowing the language and content of future revisions. The
FAA has referenced the service bulletin as ``up to Revision 2'' in
paragraphs (g)(2)(ii) and (g)(3)(iii) of this AD accordingly.
Request To Reference Latest Service Information and Provide Credit for
Previous Revision
Piaggio requested that paragraph (g)(3) of the proposed AD be
updated to reference Piaggio Aero Industries S.p.A. Service Bulletin
No. 80-0430, Revision 2, dated July 20, 2021, which is the latest
service information. In addition, Piaggio requested that the Credit for
Previous Actions specified in paragraph (h) of the proposed AD be
revised to include Piaggio Aviation S.p.A. Service Bulletin No. 80-
0430, Revision 1, dated April 30, 2019.
The FAA agrees with referencing Piaggio Aero Industries S.p.A.
Service Bulletin No. 80-0430, Revision 2, dated July 20, 2021, in the
actions required by paragraph (g)(3) of this AD. This is in addition to
Piaggio Aviation S.p.A. Service Bulletin No. 80-0430, Revision 1, dated
April 30, 2019. Because the FAA is referencing both in paragraph (g)(3)
of this AD, no change to the Credit for Previous Actions specified in
paragraph (h) of this AD is necessary. The final rule has been changed
to reference Piaggio Aero Industries S.p.A. Service Bulletin No. 80-
0430, Revision 2, dated July 20, 2021, in paragraph (g)(3) of this AD.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA reviewed the relevant
data, considered any comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on this product. Except for the
changes described previously, this AD is adopted as proposed in the
NPRM. None of the changes will increase the economic burden on any
operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Piaggio Aviation S.p.A. Service Bulletin No. 80-
0430, Revision 1, dated April 30, 2019; Piaggio Aero Industries S.p.A.
in A.S. Service Bulletin No. 80-0430, Revision 2, dated July 20, 2021;
and Piaggio Aero Industries Service Bulletin S.p.A. A.S. No. 80-0457,
Revision 1, dated February 12, 2020. This service information specifies
procedures for modifying the TAT heater circuit in order to inhibit its
engagement on the ground when the pitot heater is turned on. These
documents are distinct because they apply to airplanes in different
configurations.
The FAA reviewed Piaggio Aviation P.180 AVANTI II/EVO Temporary
Change No. 79, dated September 17, 2018, which revises the Limitations
and Normal Procedures sections of the existing AFM to include updated
procedures for airplane operation when the modification for inhibition
of the TAT heater (on ground) has been installed.
The FAA also reviewed Piaggio Aviation P.180 AVANTI Temporary
Change No. 36, dated April 11, 2019, which revises the Emergency and
Normal Procedures sections of the existing AFM to include additional
procedures to avoid air data computer failure due to water trapped and
frozen in pitot lines.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
Other Related Service Information
The FAA reviewed Piaggio Aero Industries Service Bulletin No. 80-
0454, Revision 0, dated March 6, 2017; Piaggio Aero Industries S.p.A.
Service Bulletin No. 80-0425, Revision 0, dated May 30, 2017; Piaggio
Aero Industries S.p.A Service Bulletin No. 80-0425, Revision 1, dated
December 15, 2017; and Piaggio Aero Industries S.p.A. Service Bulletin
No. 80-0425, Revision 2, dated June 4, 2018. This service information
specifies procedures for replacing the Messier-Dowty nose and main
landing gear and steering system with a Magnaghi nose and main landing
gear and Eaton steering system.
The FAA also reviewed Piaggio Aero Industries S.p.A. Service
Bulletin No. 80-0430, Revision 0, dated August 10, 2017. This service
information specifies procedures for modifying the TAT heater circuit
in order to inhibit its engagement on the ground when the pitot heater
is turned on.
Differences Between This AD and the MCAI
The MCAI requires informing all flight crews of the AFM revisions
and operating accordingly thereafter, and this AD does not because
these actions are already required by FAA operating regulations.
Costs of Compliance
The FAA estimates that this AD affects 101 airplanes of U.S.
registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.

----------------------------------------------------------------------------------------------------------------
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.
Regulatory Findings
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) 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.
