If they crack or fail, the pilot could lose control of the aircraft. The directive requires following the technical procedures outlined in **Ansett General Aviation Service Bulletin No. 7** to ensure the inspection is performed correctly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection","history":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection/history","analysis":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection/analysis","conflicts":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection/conflicts","importantCases":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection/important-cases","documents":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection/documents"}}
