- What it does
The FAA proposes to supersede Airworthiness Directive (AD) 2025-20-02, which applies to all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. AD 2025-20-02 requires incorporating a temporary revision into the existing airplane flight manual (AFM) for the affected airplanes, which revises the Abnormal Procedures Section. That action was considered an interim action. Since the FAA issued AD 2025- 20-02, updated software has been developed and instructions have been issued for installing the software. In addition, revised operational instructions have been issued that are applicable after installation of the updated software. This proposed AD would require installing the updated software and incorporating the applicable revised operational instructions into the AFM. The FAA is proposing this AD to address the unsafe condition on these products.
