Pilatus Aircraft Ltd. Airplanes
Superseded. A later AD replaced this one: AD 2023-11-05. Comply with the one in force.
This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, all serial numbers, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 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 the need to revise certain airworthiness limitations and certification maintenance instructions. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Before further flight, unless already done, revise the ALS of the existing AMM or instructions for continued airworthiness (ICA) for your airplane by incorporating the following documents.
(i) Airworthiness Limitations, AMM data module PC24-A-A04-00-0000-00A-040A-A, Issue 008, Revision 00, dated May 26, 2020, from Chapter 04, Airworthiness Limitations, Pilatus PC-24 Aircraft Maintenance Manual (PC-24 AMM) Report 02378, Issue 005, Revision 19, dated May 26, 2020.
(ii) Mandatory structural inspection items, AMM data module PC24-A-A04-20-0000-00A-000A-A, Issue 005, Revision 00, dated May 26, 2020, from Chapter 04, Airworthiness Limitations, Pilatus PC-24 Aircraft Maintenance Manual (PC-24 AMM) Report 02378, Issue 005, Revision 19, dated May 26, 2020.

(3) The actions required by paragraph (f)(1) of this AD may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a)(1) through (4), and 14 CFR 91.417(a)(2)(v).
