Unsafe Condition
Ice can accumulate on the walls of the fuel pipes within the aircraft fuel system, which can then be released downstream when fuel flow demand is increased. This released ice can collect on the FOHE front face and limit fuel flow through the FOHE, potentially leading to engine power loss and loss of control of the airplane.
