This must be done according to two specific technical maintenance manuals issued by Airbus (Service Bulletins A320-24-1013 and A320-24-1031).\n\n**Why it matters:** The wiring faults could cause the automatic landing systems—specifically the Instrument Landing System (ILS) and Autoland computers—to fail or operate incorrectly. This creates a safety risk during automated landings.\n\n**Who must comply:** All operators flying A320 model aircraft.\n\n**Deadline:** The repairs had to be completed before 31 December 1989."}},"importantCases":[],"_links":{"self":"/api/acts/ad-a320-3-automatic-flight-control-system","history":"/api/acts/ad-a320-3-automatic-flight-control-system/history","analysis":"/api/acts/ad-a320-3-automatic-flight-control-system/analysis","conflicts":"/api/acts/ad-a320-3-automatic-flight-control-system/conflicts","importantCases":"/api/acts/ad-a320-3-automatic-flight-control-system/important-cases","documents":"/api/acts/ad-a320-3-automatic-flight-control-system/documents"}}
