Airworthiness Directives; Pilatus Aircraft Ltd
Key claim: The FAA is proposing to require operators of Pilatus Model PC-24 airplanes to install updated software and revise their flight manuals to resolve an unsafe condition.
Abstract
(Proposed Rule · Transportation Department, Federal Aviation Administration) 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.
Why this matters
The proposal would address an unsafe condition on Pilatus PC-24 airplanes through software updates and flight-manual revisions, affecting both aircraft maintenance and operating documentation. It remains a proposed rule and does not itself establish final compliance obligations.
