Fuel drain lines are the tubes that allow fuel to be drained from the tanks for inspection—if they fail, they can cause dangerous fuel leaks or fire hazards.\n\n**Deadline:** The work must be completed within **100 hours of flight time** after 30 November 1978. Note that 'time in service' means actual flying hours, not calendar time.\n\n**Why it matters:** This prevents potential fuel leaks that could lead to fire hazards or engine failure in flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-60-34-fuel-drain-lines","history":"/api/acts/ad-beech-60-34-fuel-drain-lines/history","analysis":"/api/acts/ad-beech-60-34-fuel-drain-lines/analysis","conflicts":"/api/acts/ad-beech-60-34-fuel-drain-lines/conflicts","importantCases":"/api/acts/ad-beech-60-34-fuel-drain-lines/important-cases","documents":"/api/acts/ad-beech-60-34-fuel-drain-lines/documents"}}
