The work must be done exactly as described in the manufacturer’s technical document, Beechcraft Service Instruction No. 0559-281.\n\n**Who it affects**\nOnly applies to:\n*   Beechcraft model **56TC** and **A56TC** aeroplanes\n*   With serial numbers **TG-1 through TG-94**\n\n**Why it matters**\nFuel system placards tell pilots critical safety information—like which tank to use during take-off or how to switch fuel pumps. Incorrect or missing placards can lead to fuel starvation and engine failure.\n\n**What you must do**\nComplete the placard updates within **100 hours of flight time** after 31 July 1974 (the date this directive became effective)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-56-15-fuel-system-placards","history":"/api/acts/ad-beech-56-15-fuel-system-placards/history","analysis":"/api/acts/ad-beech-56-15-fuel-system-placards/analysis","conflicts":"/api/acts/ad-beech-56-15-fuel-system-placards/conflicts","importantCases":"/api/acts/ad-beech-56-15-fuel-system-placards/important-cases","documents":"/api/acts/ad-beech-56-15-fuel-system-placards/documents"}}
