This prevents the engine hose from rupturing or leaking, which could cause engine fire, failure, or loss of power in flight.\n\n**When:** The work must be completed within 100 hours of flying time after 31 October 1978.\n\n**Why it matters:** Engine hose failure at altitude can be catastrophic. This directive ensures a critical safety fix is applied to vulnerable aircraft before they accumulate significant flight hours."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-60-33-engine-hose-assembly","history":"/api/acts/ad-beech-60-33-engine-hose-assembly/history","analysis":"/api/acts/ad-beech-60-33-engine-hose-assembly/analysis","conflicts":"/api/acts/ad-beech-60-33-engine-hose-assembly/conflicts","importantCases":"/api/acts/ad-beech-60-33-engine-hose-assembly/important-cases","documents":"/api/acts/ad-beech-60-33-engine-hose-assembly/documents"}}
