## Discrepancy

AFTER T/O,  LANDING GEAR WOULD NOT RETRACT. EICAS LG AIR/GND FAIL DISPLAYED. MESSAGE APPEARED FOLLOWING ROTATION.   FOUND NLG WOW PROX SWITCH BAD. R&R'D PROX SWITCH IAW AMM 32-63-02. T/S IAW FIM 32-63-00-810-801-A. SWUNG GEAR SEVERAL TIMES. OPS CHECK GOOD. OKAY FOR SERVICE AT THIS TIME.
