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 accumulation of 

water and subsequent freezing in the 

pitot-tube, which results in pitot-tube 

blockage. This proposed AD would 

require modifying the total air 

temperature (TAT) probe heater 

electrical circuit and revising your 

existing airplane flight manual (AFM). 

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 26, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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 

2019–0144, 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 and No. 79], 

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 

Service Bulletin No. 80–0430 Revision 1 and 

Piaggio Service Bulletin No. 80–0457, 

original issue], providing modification 

instructions to inhibit on-ground power 

supply to TAT probe heater, when the pitottube 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 https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0452. 

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; and 

Piaggio Aero Industries S.p.A. Service 

Bulletin No. 80–0457, Revision 1, dated 

February 12, 2020. These service 

bulletins specify 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. Temporary Change (TC) 79 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. TC 

36 revises the Emergency and Normal 

Procedures sections of the existing AFM 

to include additional procedures to 

avoid air data computer (ADC) 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; 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. 

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 revisions 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:

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) Is not 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.

from public disclosure. If your

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI
