('Time in service' means the total time the aircraft spends operating in actual flight.)\n\n**Why it matters:**\nThe directive addresses potential safety defects in the hose assembly that could compromise aircraft systems. Compliance is mandatory to keep the aircraft legally airworthy and safe to fly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification","history":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification/history","analysis":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification/analysis","conflicts":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification/important-cases","documents":"/api/acts/ad-pa-28-73-hose-assembly-inspection-and-modification/documents"}}
