It applies to specific GAF aircraft models (the N22 and N24 series, which are small Australian-made aeroplanes).\n\n**What it requires:**\n- **Inspection of a specific part:** The control wheel assembly retaining pin — a small but critical component that helps keep the pilot's control wheel (yoke) securely attached.\n- **When to do it:** Within 10 hours of flying time after 3 July 1978.\n- **How to do it:** Follow the instructions in GAF Alert Service Bulletin AN22-27-8, Revision 1.\n\n**Why it matters:**\nIf this retaining pin fails or is missing, the pilot could lose control of the aircraft. This directive forces owners/operators to check this specific part to prevent accidents.\n\n**Who must comply:**\nAnyone operating or maintaining GAF N22 or N24 series aircraft in Australia. Non-compliance means the aircraft is not legally airworthy."}},"importantCases":[],"_links":{"self":"/api/acts/ad-gaf-n22-21-amdt-1-control-wheel-assembly-retaining-pin-inspection","history":"/api/acts/ad-gaf-n22-21-amdt-1-control-wheel-assembly-retaining-pin-inspection/history","analysis":"/api/acts/ad-gaf-n22-21-amdt-1-control-wheel-assembly-retaining-pin-inspection/analysis","conflicts":"/api/acts/ad-gaf-n22-21-amdt-1-control-wheel-assembly-retaining-pin-inspection/conflicts","importantCases":"/api/acts/ad-gaf-n22-21-amdt-1-control-wheel-assembly-retaining-pin-inspection/important-cases","documents":"/api/acts/ad-gaf-n22-21-amdt-1-control-wheel-assembly-retaining-pin-inspection/documents"}}
