This directive ensures critical hoses are replaced before they become a safety risk, keeping the aircraft airworthy."}},"importantCases":[],"_links":{"self":"/api/acts/ad-hu-369-36-flexible-hose-assembly-replacement","history":"/api/acts/ad-hu-369-36-flexible-hose-assembly-replacement/history","analysis":"/api/acts/ad-hu-369-36-flexible-hose-assembly-replacement/analysis","conflicts":"/api/acts/ad-hu-369-36-flexible-hose-assembly-replacement/conflicts","importantCases":"/api/acts/ad-hu-369-36-flexible-hose-assembly-replacement/important-cases","documents":"/api/acts/ad-hu-369-36-flexible-hose-assembly-replacement/documents"}}
