Airworthiness Directive · Amendment 39-22176 · Pitot/static system
Piaggio Aviation S.p.A. Airplanes
This AD applies to Piaggio Aviation S.p.A. Model P-180 airplanes, all serial numbers (S/Ns), certificated in any category.
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.
(1) For all airplanes: Within 30 days after the effective date of this AD, revise the existing airplane flight manual (AFM) for your airplane by adding into the Emergency Procedures and Normal Procedures sections the information in Piaggio Aviation P.180 AVANTI Temporary Change No. 36, dated April 11, 2019; or by incorporating into the Limitations and Normal Procedures sections the information in Piaggio Aviation P.180 Avanti II/EVO Temporary Change No. 79, dated September 17, 2018; as applicable to your airplane S/N. Using a different document with language identical to that in Piaggio Aviation P.180 AVANTI Temporary Change No. 36, dated April 11, 2019; or Piaggio Aviation P.180 Avanti II/EVO Temporary Change No. 79, dated September 17, 2018; is acceptable for compliance with this requirement.
(2) For airplanes identified in paragraph (g)(2)(i) and (ii) of this AD: Within 660 hours time-in-service (TIS) after the effective date of this AD or 24 months after the effective date of this AD, whichever occurs first, modify the total air temperature (TAT) probe heater electrical circuit by following the Accomplishment Instructions, paragraphs (6) through (27), in Piaggio Aero Industries S.p.A. A.S. Service Bulletin No. 80-0457, Revision 1, dated February 12, 2020.
(i) S/N 1105, if Piaggio Aero Industries Service Bulletin No. 80-0454, Revision 0, dated March 6, 2017, is not incorporated.
(ii) S/Ns 1106 through 1234 inclusive, if Piaggio Aero Industries S.p.A. Service Bulletin No. 80-0425 up to Revision 2 is not incorporated.
(3) For airplanes identified in paragraphs (g)(3)(i) through (iii) of this AD: Within 660 hours TIS after the effective date of this AD or 24 months after the effective date of this AD, whichever occurs first, modify the TAT probe heater electrical circuit by following the Accomplishment Instructions, Paragraphs (6) through (21), in Piaggio Aviation S.p.A. Service Bulletin No. 80-0430, Revision 1, dated April 30, 2019, or Accomplishment Instructions, paragraphs (6) through (21) and (25), in Piaggio Aero Industries S.p.A. in A.S. Service Bulletin No. 80-0430, Revision 2, dated July 20, 2021.
