The replacement must be part number 17766-66.\n\n**When to do it:**\nComplete this work within 100 hours of flight time after 30 November 1972, or before 1 July 1973—whichever comes first.\n\n**Why it matters:**\nThis safety directive prevents potential fuel leaks or engine failure caused by faulty fuel hose assemblies."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-20-11-flexible-fuel-hose-assembly-inspection","history":"/api/acts/ad-pa-20-11-flexible-fuel-hose-assembly-inspection/history","analysis":"/api/acts/ad-pa-20-11-flexible-fuel-hose-assembly-inspection/analysis","conflicts":"/api/acts/ad-pa-20-11-flexible-fuel-hose-assembly-inspection/conflicts","importantCases":"/api/acts/ad-pa-20-11-flexible-fuel-hose-assembly-inspection/important-cases","documents":"/api/acts/ad-pa-20-11-flexible-fuel-hose-assembly-inspection/documents"}}
