What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This proposed AD was prompted by a report that a solid-state relay (SSR) used in the left-hand (LH) windshield heating system may allow reverse current flow when in the OFF position. This proposed AD would require modification of the airplane and replacement of the affected SSR with a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.
