Specifically, it cancels **AD/CESSNA 208/20 Amdt 1**, which previously imposed safety requirements on these planes when flying in **icing conditions** (weather where ice can form on the aircraft).\n\n**Who it affects**\n\nOwners, operators, and pilots of Cessna 208 series aeroplanes (commonly called Caravans).\n\n**What changes**\n\nAs of **13 March 2008**, the requirements in the old directive no longer apply. Operators must now follow a replacement rule—**AD/CESSNA 208/21**—instead.\n\n**Why it matters**\n\nThis prevents confusion from having overlapping or outdated safety rules. By formally cancelling the old directive, the authority ensures everyone follows only the current, updated safety standard found in the new directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-208-20-amdt-1-flight-into-icing-conditions-cancelled","history":"/api/acts/ad-cessna-208-20-amdt-1-flight-into-icing-conditions-cancelled/history","analysis":"/api/acts/ad-cessna-208-20-amdt-1-flight-into-icing-conditions-cancelled/analysis","conflicts":"/api/acts/ad-cessna-208-20-amdt-1-flight-into-icing-conditions-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-208-20-amdt-1-flight-into-icing-conditions-cancelled/important-cases","documents":"/api/acts/ad-cessna-208-20-amdt-1-flight-into-icing-conditions-cancelled/documents"}}
