TASK 12-11-06-603-001
2. Refuel Operation - Inoperative Refuel Valve___________________________________________
A. General
(1)
This task refuels a fuel tank when a refuel valve does not open electrically.
(2)
There is no automatic refuel valve shutoff or overfill protection when a refuel valve is opened manually. If you put too much fuel into the tank, fuel will overfill the tank and enter the surge tank(s). If the fuel flow is not stopped, the surge tank will overfill and an overboard fuel spill will occur.
(3)
This task is a manual pressure refuel operation. The fuel quantity processor unit (FQPU) does not control the fuel load distribution during a manual pressure refuel operation. You must monitor the fuel distribution to prevent an out of limits center of gravity (CG) or lateral imbalance condition.
(4)
Do a check of the MEL for dispatch with inoperative refuel valves.
