(c)  
Install the access panel 7201 for the boost pump.

(2)  
Do these steps to do an inspection of the boost pumps for the No. 1 tank:

(a)  
Remove the access panel 7203 in the bottom wing skin to get access to the aft boost pump for the No. 1 tank.

(b)  
Do a check of the electrical bond between the aft fuel boost pump for the No. 1 tank and the airplane structure (SWPM 20-20-00). 1) Make sure the resistance is not more than 0.0002 ohm.

(c)  
Install the access panel 7203 for the boost pump.

(d)  
For the forward fuel boost pump for the No. 1 tank on airplanes without leading edge flaps covering the fuel boost pump, remove the access panel 6303 on the lower surface of the wing leading edge to get access to the forward fuel boost pump for the No. 1 tank.

(e)  
For the forward fuel boost pump for the No. 1 tank on airplanes with leading edge flaps covering the fuel boost pump, extend the leading edge flaps (AMM 27-81-0/201) to get access to the forward fuel boost pump for the No. 1 tank.

WARNING:  MAKE SURE THAT PERSONS AND EQUIPMENT ARE CLEAR OF THE LE AND TE FLAPS AND FLAP DRIVE MECHANISMS. THE LEADING EDGE AND THE TRAILING EDGE CONTROL SURFACES CAN EXTEND AND RETRACT QUICKLY. THIS CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
1)  Install the flap locks on the leading edge flaps (AMM 28-81-0/201).
WARNING:  YOU MUST CAREFULLY DO THE STEPS IN THE TASK ABOVE TO INSTALL THE LE FLAP SAFETY LOCKS. THE LE FLAPS CAN MOVE QUICKLY IF YOU DO NOT INSTALL THE SAFETY LOCKS CORRECTLY. THIS CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
(f)  
Do a check of the electrical bond between the forward fuel boost pump for the No. 1 tank and the airplane structure (SWPM 20-20-00). 1) Make sure the resistance is not more than 0.0002 ohm.

(g)  
Install the access panel 6303 for the fuel boost pump if you removed it.

(h)  
Remove the flap locks from the leading edge flaps if you installed them (AMM 27-81-0/301).

WARNING:  YOU MUST CAREFULLY DO THE STEPS IN THE TASK ABOVE TO REMOVE THE LE FLAP SAFETY LOCKS. THE LE FLAPS CAN MOVE QUICKLY IF YOU DO NOT REMOVE THE SAFETY CORRECTLY. THIS CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.

(i)  
Retract the leading edge flaps if they are extended (AMM 27-81-0/201).

WARNING:  MAKE SURE THAT PERSONS AND EQUIPMENT ARE CLEAR OF THE LE AND TE FLAPS AND FLAP DRIVE MECHANISMS. THE LEADING EDGE AND THE TRAILING EDGE CONTROL SURFACES CAN EXTEND AND RETRACT QUICKLY. THIS CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
