Flight Controls - Ground Spoiler Actuator Hydraulic Hose and Associated Fittings - Replacement
Federal Aviation Administration Airworthiness Directive 2023-08-03 is a final rule addressing certain Gulfstream Aerospace Corporation Model G-1159A, G-1159B, G-IV, and GIV-X airplanes. This directive requires replacement of the ground spoiler actuator hydraulic hoses and associated fittings to prevent improper hydraulic line connections that could cause unintended asymmetrical spoiler deployment. The AD aims to enhance flight safety by mitigating the risk of loss of control due to this hydraulic issue.
