Airworthiness Directives; Piaggio Aero 

Industries S.p.A Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: 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. 

DATES: The FAA must receive comments 

on this proposed AD by May 23, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

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 https://

www.regulations.gov 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

Action Labor cost Parts cost Cost per 

airplane 

Cost on U.S. 

operators 

Revise AFM ....................................... 1 work-hour × $85 per hour = $85 ........................... Not Applicable .. $85 $8,585 

Update Maintenance Manual ............ 1 work-hour × $85 per hour = $85 ........................... Not Applicable .. 85 8,585

20792 Federal Register / Vol. 87, No. 68 / Friday, April 8, 2022 / Proposed Rules 

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,

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 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 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

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

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–
