These parts manage moisture and contaminants in compressed air systems (pneumatic systems).\n\n**Who it affects:** Anyone operating aircraft fitted with these specific Dunlop parts.\n\n**The deadline:** Operators had to remove these parts before any further flight after 31 July 1970.\n\n**Why it matters:** This prevents potential failures in aircraft pneumatic systems by removing specific components that were deemed unsafe or obsolete."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pneu-2-oil-and-water-traps-retirement","history":"/api/acts/ad-pneu-2-oil-and-water-traps-retirement/history","analysis":"/api/acts/ad-pneu-2-oil-and-water-traps-retirement/analysis","conflicts":"/api/acts/ad-pneu-2-oil-and-water-traps-retirement/conflicts","importantCases":"/api/acts/ad-pneu-2-oil-and-water-traps-retirement/important-cases","documents":"/api/acts/ad-pneu-2-oil-and-water-traps-retirement/documents"}}
