This must be completed within 25 hours of flight time after 21 August 1970.\n\n**Why it matters:** Faulty engine mount bolts could cause the engine to separate from the aircraft wing during flight, with catastrophic consequences. **Note on this version:** Amendment 1 simply groups the Queen Air 65 and 70 series models together under one directive for administrative clarity—it doesn't change the actual safety requirement."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-16-amdt-1-engine-mount-bolt-nuts","history":"/api/acts/ad-beech-65-16-amdt-1-engine-mount-bolt-nuts/history","analysis":"/api/acts/ad-beech-65-16-amdt-1-engine-mount-bolt-nuts/analysis","conflicts":"/api/acts/ad-beech-65-16-amdt-1-engine-mount-bolt-nuts/conflicts","importantCases":"/api/acts/ad-beech-65-16-amdt-1-engine-mount-bolt-nuts/important-cases","documents":"/api/acts/ad-beech-65-16-amdt-1-engine-mount-bolt-nuts/documents"}}
