## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2021-10-28, which applies to all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. AD 2021-10-28 requires 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 has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require 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 proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
