The FAA amends § 39.13 by adding the following new airworthiness directive: 2026-08-11 Pilatus Aircraft Ltd.: Amendment 39-23319; Docket No. FAA-2026-3862; Project Identifier MCAI-2026-00317-A. (a) Effective Date This airworthiness directive (AD) is effective May 11, 2026. (b) Affected ADs None.

(d) Subject Joint Aircraft System Component (JASC) Code 3240, Landing Gear Brake System. (e) Unsafe Condition 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, resulting in brake lockup.
