Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Piaggio Aero Industries S.p.A. (Piaggio) 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 identifies the unsafe condition as altimetry system errors in the air data computers (ADCs) and stand-by instrument systems. This proposed AD would require amending the existing airplane flight manual (AFM), installing improved ADCs and a detachable configuration module (DCM), and revising the existing instructions for continued airworthiness. The FAA is proposing this AD to address the unsafe condition on these products.

Background
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, has issued
EASA AD 2019-0269, dated October 29, 2019 (referred to after this as
``the MCAI''), to address the unsafe condition on Piaggio Model P.180
Avanti II airplanes. The MCAI states:
During monitoring of P.180 Avanti II fleet by EUROCONTROL
(checks performed by Air Traffic Control stations) a mean altimetry
system error and some singular measurement exceedances were reported
being outside of limits defined by rules applicable to Reduced
Vertical Separation Minimum (RVSM) airworthiness standards.
Subsequent investigation determined that the static source error
correction curves embedded in the ADC of pilot and co-pilot, as well
as in the stand-by instrument system, did not ensure the required
RVSM performance of the aeroplane.
This condition, if not corrected, could lead to delivery [of]
erroneous air data information and consequent impairment of
aeroplane altitude-keeping capability, possibly resulting in a mid-
air collision within RVSM airspace.
To address this potential unsafe condition, Piaggio issued the
AFM TC [Temporary Change No. 107] introducing additional limitations
for operation within RVSM airspace and issued the SB [Piaggio
Aerospace Service Bulletin 80-0467] providing instructions to modify
the aeroplane.
For the reasons described above, this [EASA] AD requires
amendment of the AFM and modification of the aeroplane by installing
improved ADCs and DCM.
You may examine the MCAI in the AD docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2022-
0397.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Piaggio Aero Industries S.p.A. A.S. Service
Bulletin No. 80-0467, Revision 2, dated March 6, 2020, which specifies
procedures for replacing the two ADCs and the DCM with improved parts.
The FAA also reviewed Piaggio Aviation P.180 Avanti II/EVO
Temporary Change No. 107, dated September 17, 2019, which updates the
limitations section of the AFM by prohibiting operations in RVSM
airspace if the ADCs and DCM have not been replaced.
In addition, the FAA reviewed Piaggio Aviation P.180 Avanti EVO
Maintenance Manual Temporary Revision No. 126, dated June 6, 2019,
which updates and adds certain tasks for the navigation system.
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.
FAA's Determination
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 is issuing this NPRM
after determining the unsafe condition described previously is likely
to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Differences Between This Proposed AD and the MCAI
The MCAI requires informing all flight crews of the AFM revision
and operating accordingly thereafter, and this proposed AD would not
because those actions are already required by FAA operating
regulations.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 101 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost airplane operators
----------------------------------------------------------------------------------------------------------------
Revise AFM..................... 1 work-hour x $85 per Not Applicable........ $85 $8,585

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
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) Would not be a ``significant regulatory action'' under
Executive Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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:
Piaggio Aero Industries S.p.A.: Docket No. FAA-2022-0397; Project
Identifier MCAI-2021-01354-A.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by May 23, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Piaggio Aero Industries S.p.A. Model P-180
airplanes, serial number (S/N) 1002 and S/Ns 1105 through 3010
inclusive, certificated in any category.
(d) Subject
Joint Aircraft System Component (JASC) Code 3417, Air Data
Computer.
(e) Unsafe Condition
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 identifies the unsafe condition as altimetry
system errors in the air data computers (ADCs) and stand-by
instrument systems. The FAA is issuing this AD to prevent a mean
altimetry system error measurement from exceeding the limits defined
for operations within airspace designed as reduced vertical
separation minimum (RVSM) airspace. The unsafe condition, if not
addressed, could result in a potential mid-air collision within RVSM
airspace.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
(1) Within 24 months after the effective date of this AD, revise
the Limitations section of the existing airplane flight manual (AFM)
for your airplane by adding the information in Piaggio Aviation
P.180 Avanti II/EVO Temporary Change No. 107, dated September 17,
2019. Using a different document with language identical to that on
page 2-33-bis or 2-33.C-bis (as applicable to the S/N of your
airplane) of Piaggio Aviation P.180 Avanti II/EVO Temporary Change
No. 107, dated September 17, 2019, is acceptable for compliance with
this requirement.
(2) Within 660 hours time-in-service after the effective date of
this AD or 24 months after the effective date of this AD, whichever
occurs first, modify the airplane by replacing the ADCs and
detachable configuration module (DCM) in accordance with the
Accomplishment Instructions, paragraphs (5) through (14), of Piaggio
Aero Industries S.p.A. A.S. Service Bulletin No. 80-0467, Revision
2, dated March 6, 2020, and revise the instructions for continued
airworthiness for your airplane by incorporating the information in
Piaggio Aviation P.180 Avanti EVO Maintenance Manual Temporary
Revision No. 126, dated June 6, 2019.
(3) The AFM revision required by paragraph (g)(1) of this AD, if
included, may be removed after completing the actions required by
paragraph (g)(2) of this AD.
(4) As of the effective date of this AD, do not install on any
airplane an ADC part number (P/N) 822-1109-018, DCM P/N 501-1870-31,
or DCM P/N 501-1870-51.
(h) Alternative Methods of Compliance (AMOCs)
(1) The Manager, International Validation Branch, FAA, has the
authority to approve AMOCs for this AD, if requested using the
