## Abstract

The FAA is superseding Airworthiness Directive (AD) 2021-10- 28, which applied to all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. AD 2021-10-28 required incorporating new revisions to the airworthiness limitations section (ALS) of the existing airplane maintenance manual (AMM) or Instructions for Continued Airworthiness (ICA) to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2021-10-28, the FAA determined that new or more restrictive airworthiness limitations are necessary. This AD requires revising the ALS of the existing AMM or ICA for your airplane, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
