Airworthiness Directive · Amendment 39-23455 · Windshield/door rain/ice removal
Pilatus Aircraft Ltd. Airplanes
This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency AD 2026-0008, dated January 15, 2026 (EASA AD 2026-0008).
The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This 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 AD requires modification of the airplane and replacement of the affected SSR with a serviceable part. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2026-0008.
(1) Where EASA AD 2026-0008 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not adopt the “Remarks” section of EASA AD 2026-0008.
Although the material referenced in EASA AD 2026-0008 specifies to submit certain information, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
