A. Install the Airbus Flight Operations and MAintenance eXchanger (FOMAX) gatelink-antenna:
(1) Make sure that the parts retained from the removed component are clean and in the correct condition.
(2) Clean the component interfaces and the adjacent area.
(3) Do an inspection of the component interfaces and the adjacent area.
(4) Put and hold the Airbus FOMAX gatelink-antenna (3) in position on the bracket (4).
(5) Make sure that you can see the label on the Airbus FOMAX gatelink-antenna (3).
(6) Attach the Airbus FOMAX gatelink-antenna (3) with the four screws (2).
(7) Prepare for the electrical bonding (Ref. AMM TASK 20-28-00-912-802).
.
(9) Make sure that the bonding contact resistance between the Airbus FOMAX gatelink-antenna (3) and the fuselage structure is not more than five milliohms (Ref. AMM TASK 20-28-00-912-802).
(10) Remove the CAP-BLANKING from each electrical connector and receptacle.
(11) Connect the electrical connector (1) to the electrical connector (5).
(a) TORQUE the electrical connector (1) to between 6.1 and 4.1 lbf.in (0.07 and 0.05 m.daN ) .
(12) Installation of the lockwire.
