Citation X motive flow pump flush on the road. An AOG customer called SEAL Aviation to come to their location to perform a motive flow system pump flush procedure AMM 28-20-00 on a Citation 750. This procedure is required when the engine driven fuel pump internally becomes damaged depositing metal debris in the fuel system. This involves defueling the aircraft and temporarily bypassing numerous fuel system components to flush debris from the system. Once the fuel system is properly prepared, debris can be pumped from the affected fuel tank and lines. This process is then repeated until all the debris is cleared from the fuel system. Debris caught in the fuel system can lead to numerous issues such as clogged lines, filters and damage to sensitive system components, leading to costly repairs. Once the flush is complete, the fuel tank need to be inspected thoroughly and engine runs need to be preformed to ensure there are no leaks in the fuel system. SEAL Aviation is an industry leader in maintaining Citation aircraft fuel systems. Combined with our mobile capabilities, this makes SEAL Aviation uniquely positioned to quickly respond to Citation AOG fuel system issues.
