When an AD is superseded, operators must follow the *newer* directive, not this old one.\n- This document serves as a historical reference point — it tells aviation professionals that the old rule no longer applies and directs them to the current version.\n\n**Key takeaway:** If you operate a Bell 204 helicopter, don't use this document for compliance. Check **DCA/BELL 204/6 Amendment 3** instead."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-204-9-superseded-by-dca-bell-204-6-amdt-3","history":"/api/acts/ad-bell-204-9-superseded-by-dca-bell-204-6-amdt-3/history","analysis":"/api/acts/ad-bell-204-9-superseded-by-dca-bell-204-6-amdt-3/analysis","conflicts":"/api/acts/ad-bell-204-9-superseded-by-dca-bell-204-6-amdt-3/conflicts","importantCases":"/api/acts/ad-bell-204-9-superseded-by-dca-bell-204-6-amdt-3/important-cases","documents":"/api/acts/ad-bell-204-9-superseded-by-dca-bell-204-6-amdt-3/documents"}}
