This prevents fuel from accidentally siphoning out of the tanks during flight.\n\n**When:** The modification must be completed within 100 hours of flight time after 30 November 1979.\n\n**How:** Follow the instructions in Cessna Service Information Letter No. ME79-26."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-50-wing-locker-fuel-tank-filler-cap-rework","history":"/api/acts/ad-cessna-310-50-wing-locker-fuel-tank-filler-cap-rework/history","analysis":"/api/acts/ad-cessna-310-50-wing-locker-fuel-tank-filler-cap-rework/analysis","conflicts":"/api/acts/ad-cessna-310-50-wing-locker-fuel-tank-filler-cap-rework/conflicts","importantCases":"/api/acts/ad-cessna-310-50-wing-locker-fuel-tank-filler-cap-rework/important-cases","documents":"/api/acts/ad-cessna-310-50-wing-locker-fuel-tank-filler-cap-rework/documents"}}
