EASA AD US-2022-02-15
Landing Gear - Nose Wheel Steering Servo Valve Manifold - Replacement / Aeroplane Flight Manual - Revision
The FAA Airworthiness Directive 2022-02-15 is a final rule addressing all Gulfstream Aerospace Corporation Model G-IV airplanes. It mandates the replacement of the nose wheel steering servo valve manifold and the incorporation of revised operating procedures into the Airplane Flight Manual to prevent un-commanded nose wheel steering turns caused by moisture freezing in the servo valve. This directive corrects a typographical error in the previously issued AD 2020-12-06 regarding the citation of the Airplane Flight Manual document.
