Plain English Summary

1/10 complexity

What this is: This is an Airworthiness Directive (AD) — a mandatory safety order issued by the Civil Aviation Safety Authority (CASA) under Commonwealth aviation law. Think of it as a legally enforceable recall notice for aircraft.

What it requires: Owners and operators must conduct a mandatory inspection of the aileron control system (the mechanical components that move the wing flaps to control the aircraft's roll) on specific Gulfstream business jets.

Who it affects: Only Gulfstream (Grumman) G1159 and G-IV series aeroplanes with serial numbers 1 through 119, plus serial number 775.

When it must be done: Within 100 hours of flight time after 31 August 1973, unless the work has already been completed.

Why it matters: Defects in aileron controls can cause loss of roll authority, potentially leading to loss of aircraft control. This directive mandates compliance with Grumman Customer Bulletin No. 163 to prevent catastrophic failures.
