(1)  
Use the operator supplied procedures to position the fuel vehicle.

WARNING:  DO NOT POSITION FUEL SERVICING EQUIPMENT OR AIRPLANE SERVICING EQUIPMENT UNDER THE WING DURING AN OVERWING REFUEL OPERATION.  AN OVERWING FUEL SPILL CAN CAUSE FUEL TO FLOW FROM THE WING SURFACE ONTO EQUIPMENT UNDER THE WING.  A FUEL SPILL CAN CAUSE A FIRE OR EXPLOSION.

(2)  
Connect a grounding cable from an approved earth ground to an approved electrical ground point on the airplane (static ground) (AMM 20-40-11/201).

WARNING:  YOU MUST GROUND THE AIRPLANE TO AN APPROVED EARTH GROUND AND BOND THE REFUEL SOURCE BEFORE THE OVERWING REFUEL OPERATION.  IF YOU DO NOT FOLLOW THIS PROCEDURE, A STATIC SPARK CAN CAUSE FUEL VAPOR TO IGNITE.

(3)  
Connect a grounding cable from the fueling source to an approved earth ground   (AMM 20-40-11/201).

(4)  
Connect a bonding cable from the fueling source to an approved airplane electrical ground point (AMM 20-40-11/201).

(5)  
Put on a safety harness and connect the harness to the supplied harness receptacle.

WARNING:  YOU MUST WEAR A SAFETY HARNESS WHEN YOU DO AN OVERWING REFUEL OPERATION.  A SERIOUS INJURY CAN OCCUR IF YOU FALL FROM THE WING SURFACE.

WARNING:  MAKE SURE THE FUEL LEVEL FOR THE APPLICABLE TANK IS BELOW THE LEVEL OF THE FILL PORT BEFORE YOU OPEN THE FILL CAP.  A FUEL SPILL CAN OCCUR.  A FUEL SPILL CAN CAUSE A FIRE OR AN EXPLOSION.
CAUTION:  KEEP ALL LOOSE OBJECTS AWAY FROM THE FILL PORT.  REMOVE ANY OBJECTS FROM YOUR SHIRT POCKET (PENS, CIGARETTES, LIGHTERS, ETC.) BEFORE YOU OPEN THE FILL CAP.  IF AN OBJECT DOES FALL INTO THE FUEL TANK, CONTACT AN AIRLINE REPRESENTATIVE.  FIND AND REMOVE THE OBJECT IMMEDIATELY. UNWANTED OBJECTS IN THE FUEL TANK CAN CAUSE DAMAGE TO IN-TANK EQUIPMENT AND ELECTRICAL WIRING.
(c)  
Connect the overwing nozzle to the fill port.

(d)  
Use a nozzle extension or spout to make sure the fuel does not splash into the fuel tank.

(e)  
Make sure the nozzle extension is below the level of the fuel.

(f)  
Make sure the overwing nozzle remains in contact with the fill port during the refuel operation.

C.  Overwing Refuel Operation
(1)  
Record these values on the fuel sheet:

(a)  
Pre-uplift fuel quantity for each tank.

NOTE:  If there is not electrical power, use the fuel measuring sticks to calculate the pre-uplift fuel quantity in each tank.

(b)  
Final fuel quantity necessary in each tank.

(c)  
Fuel to be uplifted converted to volume.

(2)  
Use the fueling quantity indicators (P15 panel), fuel quantity indicators in the flight compartment, or fuel measuring sticks to monitor the fuel quantity.

(3)  
Activate the fuel shutoff control switch (deadman switch) to start the fuel flow.

(4)  
Make sure the refuel rate for each tank is a maximum of 155 U.S. gallons (580 liters) per minute.
