This AD addresses a known defect in the deicing system on these specific aircraft. The fix must be done according to Beechcraft's own Service Instruction No. 0822-193.\n\n**Who must act:** Anyone operating these specific Beechcraft 200 models in Australia.\n\n**The deadline:** Within 100 hours of flying time after 31 August 1976.\n\n**Key point:** This is a **historical directive** from 1976. While it remains on the books, it only applies to aircraft that were in service at that time and haven't had the work done. Modern operators would have long since complied."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-200-10-wing-deicer-lines","history":"/api/acts/ad-beech-200-10-wing-deicer-lines/history","analysis":"/api/acts/ad-beech-200-10-wing-deicer-lines/analysis","conflicts":"/api/acts/ad-beech-200-10-wing-deicer-lines/conflicts","importantCases":"/api/acts/ad-beech-200-10-wing-deicer-lines/important-cases","documents":"/api/acts/ad-beech-200-10-wing-deicer-lines/documents"}}
