This is done following the manufacturer's instructions in **Cessna Service Information Letter ME82-42**.\n\n**Why does this matter?**\nThe manufacturer discovered these aircraft were built with insufficient space between a fuel hose and the hot exhaust pipe. If the hose touches the exhaust, it can wear through (a process called *chafing*) and leak fuel. Fuel spraying onto a hot exhaust creates a severe **fire and explosion risk**.\n\n**When must it be done?**\nWithin 100 hours of flight time after 30 November 1982."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-303-1-fuel-hose-clamping-improvement","history":"/api/acts/ad-cessna-303-1-fuel-hose-clamping-improvement/history","analysis":"/api/acts/ad-cessna-303-1-fuel-hose-clamping-improvement/analysis","conflicts":"/api/acts/ad-cessna-303-1-fuel-hose-clamping-improvement/conflicts","importantCases":"/api/acts/ad-cessna-303-1-fuel-hose-clamping-improvement/important-cases","documents":"/api/acts/ad-cessna-303-1-fuel-hose-clamping-improvement/documents"}}
