It has been replaced by a newer, broader safety directive (**AD/GENERAL/74 Amendment 1**) that covers multiple aircraft types under one rule.\n\n**Who it affects:** Owners and operators of Short SC7 Skyvan aircraft. They no longer need to follow this specific directive, but must comply with the replacement general directive instead."}},"importantCases":[],"_links":{"self":"/api/acts/ad-sc7-9-front-pilot-seats-restraint-installations-modification-cancelled","history":"/api/acts/ad-sc7-9-front-pilot-seats-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-sc7-9-front-pilot-seats-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-sc7-9-front-pilot-seats-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-sc7-9-front-pilot-seats-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-sc7-9-front-pilot-seats-restraint-installations-modification-cancelled/documents"}}
