Plain English Summary

2/10 complexity

What this is: A mandatory safety instruction (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority for specific Gulfstream aircraft.

Who it affects: Owners and operators of Gulfstream G1159 and G-IV series aeroplanes (all models).

What you must do: Carry out maintenance and inspections on the aileron hydraulic system exactly as described in Gulfstream Customer Bulletin 224A. (The ailerons are the flaps on the wings that control the aircraft's roll; their hydraulic system powers these critical flight controls.)

Why this matters: This ensures the aileron hydraulic system works safely and prevents potential flight control failures.

What changed: This update (Amendment 1) replaces the previous requirement to follow older manufacturer alerts (ACB #7 and CB 224) with the current standard (CB 224A). The safety goal remains the same—only the specific technical instructions have been updated.
