This reflects a system change where Australia automatically recognises safety directives from an aircraft's country of design under new Civil Aviation Safety Regulations (Part 39.001A).\n\n**Who it affects:**\nOwners and operators of Fokker F100 series aircraft. They must now comply with the European directive instead of this cancelled Australian rule."}},"importantCases":[],"_links":{"self":"/api/acts/ad-f100-86-flight-controls-horizontal-stabiliser-control-unit-cancelled","history":"/api/acts/ad-f100-86-flight-controls-horizontal-stabiliser-control-unit-cancelled/history","analysis":"/api/acts/ad-f100-86-flight-controls-horizontal-stabiliser-control-unit-cancelled/analysis","conflicts":"/api/acts/ad-f100-86-flight-controls-horizontal-stabiliser-control-unit-cancelled/conflicts","importantCases":"/api/acts/ad-f100-86-flight-controls-horizontal-stabiliser-control-unit-cancelled/important-cases","documents":"/api/acts/ad-f100-86-flight-controls-horizontal-stabiliser-control-unit-cancelled/documents"}}
