WARNING:  OBEY ALL REFUEL OPERATION PRECAUTIONS IN AMM 12-11-01/301. FAILURE TO OBEY THE REFUEL PRECAUTIONS CAN CAUSE SERIOUS INJURY TO PERSONS AND DAMAGE TO EQUIPMENT.

(2)
Do this task: Prepare the Airplane for a Refuel Operation (AMM 12-11-01/301).

C.  Connect the Fueling Equipment
(1)  
Do the operator supplied procedures to position the fuel vehicle.

(2)  
Connect a bonding cable from the fueling source to an approved electrical grounding or bonding connection on the airplane (AMM 20-40-11/201).

CAUTION:  OBEY THE PRECAUTIONS IN AMM 20-40-11/201 FOR ATTACHMENT OF BONDING CABLES.  AN ADEQUATE ELECTRICAL BOND MAY NOT EXIST IF THE BONDING CABLES ARE NOT INSTALLED AT APPROVED AIRPLANE GROUND CONNECTIONS.  IF THE FUEL SERVICE EQUIPMENT AND AIRPLANE ARE NOT CORRECTLY BONDED, A FIRE OR EXPLOSION CAN OCCUR.

(3)  
Open the fueling station access door to get access to the fueling station.

(4)  
Connect the bonding cable attached to the refuel nozzle to an approved airplane electrical ground (AMM 20-40-11/201).

NOTE:  The bonding cable is not necessary if there is electrical continuity between the fueling source and the fueling nozzle.

(5)  
Connect the fuel hose to the fueling receptacle adapter:

(a)  
Remove the fueling receptacle cap (if installed).

(b)  
Make sure there are no fuel leaks.

(c)  
Make sure the fueling receptacle adapter is clean and not damaged.

(d)  
Connect the refuel nozzle to the fueling receptacle.

(6)  
AIRPLANES WITH AN AUXILIARY TANK; Open the defueling valve access door and put the defueling valve handle to the OPEN position.

D.  Prepare the Fueling Panel, P15
(1)  
Fully open the fueling station access door.

(2)  
Make sure the panel floodlights come on.

(3)  
If the floodlights do not come on (no ground power), then do this step:

(a) Hold the test gage switch in the AUX FUELING POWER CONTROL position.

(4)  
Test the indicator lights:

(a)  
Push the PRESS TO TEST indicator lights.

(b)  
Make sure each light comes on when pushed.

(5)  
If the test gage switch is not in the AUX FUELING POWER CONTROL position, test the fueling quantity indicators:

(a)  
Put and hold the test gage switch to TEST GAGES & FUELING PRECHECK or to TEST GAGES position.

(b)  
Make sure the fueling quantity indicators show downscale pointer mover (dial indicator) or show countdown or all 8's (digital indicators).

(c)  
Release the test gage switch.

(d)  
Make sure all the fueling quantity displays go back to the usual indication.

E.  Prepare the Fuel Sheet
(1)  
Use the operator supplied fuel sheet to record the pre-uplift fuel quantity for each tank.

(2)  
Calculate the fuel to be uplifted converted to volume (if necessary).

(3)  
Record the uplift quantity on the fuel sheet (if necessary).

F.  Begin the Refuel Operation
(1)  
Put all the fueling shutoff (refuel) valve switches to the OPEN position.

(2)  
Activate the fuel shutoff control switch (deadman switch) to start the fuel flow.

(3)  
Make sure the refuel pressure is between 35 and 55 psi.

(a)  
This pressure corresponds to a maximum fueling rate of 500 gallons per minute if you fuel all the tanks simultaneously.

(b)  
Aircraft with bladder cells will be restricted to 450 gallons per minute at 55 PSIG

(4)  
Make sure the refuel valve indication lights come on (valves open).

(5)  
Make sure the left and right wing fuel tanks refuel at approximately the same rate.

(6)  
Monitor the fueling quantity indicators and the refuel valve indication lights.

G.  Stop the Refuel Operation
(1)  Release the deadman switch to stop the fuel flow when all of the fueling shutoff (refuel) valve position lights are off or when the fueling quantity indicators show the predetermined quantities of fuel.
NOTE:  The volumetric top-off unit or the fuel tank float switch (whichever is installed) will close the tank refuel valve(s) when the fuel tank quantity is at the full level.
If a volumetric top-off (VTO) unit and a backup float switch are installed, if the VTO unit fails to close a tank refuel valve, the backup float switch will close the refuel valve. However the fueling quantity indicator will not show the correct quantity of fuel in the tank (approximately +200-300 pounds/+91-136 kilograms).  Use the fuel quantity indicator in the flight compartment to determine the correct fuel quantity.
