This is administrative housekeeping to reduce regulatory duplication.\n\n**Who is affected**\nOwners and operators of Boeing 727 aircraft. They must now follow the requirements in the consolidated directive rather than this cancelled one.\n\n**Key date**\nThe cancellation took effect on 7 July 2005."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b727-149-elevator-rear-spar-2-cancelled","history":"/api/acts/ad-b727-149-elevator-rear-spar-2-cancelled/history","analysis":"/api/acts/ad-b727-149-elevator-rear-spar-2-cancelled/analysis","conflicts":"/api/acts/ad-b727-149-elevator-rear-spar-2-cancelled/conflicts","importantCases":"/api/acts/ad-b727-149-elevator-rear-spar-2-cancelled/important-cases","documents":"/api/acts/ad-b727-149-elevator-rear-spar-2-cancelled/documents"}}
