AD FAA-2026-3862

Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes

Summary

The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47G airplanes. This AD was prompted by a report that a brake shuttle valve (BSV) on a production airplane shuttled and isolated the brake line to the left- hand (LH) brake, which resulted in brake lockup. This AD requires replacement of the LH and right-hand (RH) brake pipe assemblies and also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
