What it does

The FAA is superseding Airworthiness Directive (AD) 2023-11- 05, which applied to all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. AD 2023-11-05 required revising the airworthiness limitations section (ALS) of the existing aircraft maintenance manual (AMM) or instructions for continued airworthiness (ICA) to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-11-05, the FAA has 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. The FAA is issuing this AD to address the unsafe condition on these products.
