The original rule required modifications to prevent flap system failures, but authorities determined these changes are no longer necessary for safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-23-17-electric-flap-system-mechanism-cancelled","history":"/api/acts/ad-beech-23-17-electric-flap-system-mechanism-cancelled/history","analysis":"/api/acts/ad-beech-23-17-electric-flap-system-mechanism-cancelled/analysis","conflicts":"/api/acts/ad-beech-23-17-electric-flap-system-mechanism-cancelled/conflicts","importantCases":"/api/acts/ad-beech-23-17-electric-flap-system-mechanism-cancelled/important-cases","documents":"/api/acts/ad-beech-23-17-electric-flap-system-mechanism-cancelled/documents"}}
