Piaggio Aero Industries S.p.A Airplanes
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.
The FAA is adopting a new airworthiness directive (AD) for certain Piaggio Aero Industries S.p.A. (Piaggio) Model P-180 airplanes. This AD is 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. This AD requires 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 issuing this AD to address the unsafe condition on these products.
(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.
