This must be done to prevent dangerous fuel leaks that could cause fires.\n\n**Why it exists:** An aircraft operator found a fuel hose that was severely kinked and nearly cracked all the way through during routine maintenance. This created a serious fire risk.\n\n**When you must comply:** Complete the work within 100 hours of flying time, or at the next annual inspection—whichever comes first after 31 December 1993.\n\n**Who it affects:** All owners and operators of Piper and Ted Smith Aerostar series aircraft, unless they have already completed this specific work."}},"importantCases":[],"_links":{"self":"/api/acts/ad-tsa-600-40-amdt-1-nacelle-fuel-and-oil-pressure-hoses","history":"/api/acts/ad-tsa-600-40-amdt-1-nacelle-fuel-and-oil-pressure-hoses/history","analysis":"/api/acts/ad-tsa-600-40-amdt-1-nacelle-fuel-and-oil-pressure-hoses/analysis","conflicts":"/api/acts/ad-tsa-600-40-amdt-1-nacelle-fuel-and-oil-pressure-hoses/conflicts","importantCases":"/api/acts/ad-tsa-600-40-amdt-1-nacelle-fuel-and-oil-pressure-hoses/important-cases","documents":"/api/acts/ad-tsa-600-40-amdt-1-nacelle-fuel-and-oil-pressure-hoses/documents"}}
