Airworthiness Directive · Amendment 39-22222 · Fuselage main, plate/skin
Piaggio Aviation S.p.A. (Type Certificate Previously Held by Piaggio Aero Industries S.p.A.) Airplanes
This AD applies to Piaggio Aviation S.p.A. (type certificate previously held by Piaggio Aero Industries S.p.A.) (Piaggio) Model P-180 airplanes, serial number (S/N) 1174 through 1214 inclusive and S/N 1218 through 1230 inclusive, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Piaggio Aviation S.p.A. (type certificate previously held by Piaggio Aero Industries S.p.A.) (Piaggio) Model P-180 airplanes. 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 corrosion in the bottom fuselage area of the cabin compartment due to inner and outer sides of fuselage skin panels of certain airplanes treated with the less effective primer. This AD requires repetitively inspecting the fuselage skin panels, visually inspecting the entire fuselage inner side skin if necessary, and taking any necessary corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 12 months after the effective date of this AD, do the applicable inspections and corrective actions on each fuselage skin panel in accordance with the Accomplishment Instructions, Part A, paragraphs (1) through (15) and (17) through (20), or Part A (Alternate Procedure), paragraphs (31) through (37), (41) through (43), (50) through (55), and (57) through (60), in Piaggio Service Bulletin 80-0405, Revision 0, dated March 15, 2021, as corrected by Piaggio Service Bulletin 80-0405, Revision 0, Errata Corrige No. 1, dated March 24, 2021 (Piaggio SB 80-0405), except for the following:
(i) You are not required to contact the manufacturer. Instead, for any repairs, use a method approved by the FAA or the European Union Aviation Safety Agency (EASA).
(ii) Where the steps in Part A or Part A (Alternate Procedure) reference Part B, you must follow the Accomplishment Instructions, Part B, paragraphs (82) through (86), (88), and (104) of Piaggio SB 80-0405.
(2) If, as part of the corrective actions required by paragraph (g)(1) of this AD, you repaired areas of the fuselage skin but did not replace the panels, do the following:
(i) Within 60 days after completing the actions required by paragraph (g)(1) of this AD, report the inspection results, including the information specified in the Confirmation Slip attached to Piaggio SB 80-0405, to Piaggio at technicalsupport@piaggioaerospace.it; and
(ii) Repeat the requirements of paragraph (g)(1) of this AD at intervals not to exceed 660 hours time-in-service (TIS) or 26 months, whichever occurs first.
(3) If, as part of the corrective actions required by paragraph (g)(1) of this AD, you replaced the panels, within 60 days after completing the actions required by paragraph (g)(1) of this AD, report the inspection results, including the information specified in the Confirmation Slip attached to Piaggio SB 80-0405, to Piaggio at technicalsupport@piaggioaerospace.it.
(4) If, during all of the inspections required by paragraph (g)(1) of this AD, there is no corrosion and no primer inconsistencies, no further action is required by this AD.
