This maintenance must be completed within 100 hours of flight time after the specified deadline.\n\n**Why it matters:**\nLong-term exposure to aviation fuel can cause the sealant to deteriorate and break apart. If this happens, pieces of sealant can contaminate the fuel filter and engine fuel system, potentially causing engine problems or failure."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rock-114-9-fuel-tank-access-door-sealant-replacement","history":"/api/acts/ad-rock-114-9-fuel-tank-access-door-sealant-replacement/history","analysis":"/api/acts/ad-rock-114-9-fuel-tank-access-door-sealant-replacement/analysis","conflicts":"/api/acts/ad-rock-114-9-fuel-tank-access-door-sealant-replacement/conflicts","importantCases":"/api/acts/ad-rock-114-9-fuel-tank-access-door-sealant-replacement/important-cases","documents":"/api/acts/ad-rock-114-9-fuel-tank-access-door-sealant-replacement/documents"}}
