## Discrepancy

AFTER TAKEOFF, THE LANDING GEAR LEVER WAS SELECTED UP BUT NONE OF THE GEAR CAME UP. WE GOT THE LANDING GEAR SWITCH DISAGREE CAS AND THE QRH HAD US CYCLE THE HANDLE. UPON THE SECOND ATTEMPT TO RAISE THE LANDING GEAR, THE GEAR HANDLE PHYSICALLY WOULD NOT COME UP. WE CONTINUED THE FLIGHT WITH THE GEAR DOWN. THE INITIAL CAS MESSAGE WENT AWAY, AND NO FURTHER MESSAGES EVER APPEARED.   ARRIVED ON SITE AND PREPPED AIRCRAFT FOR MX. GAINED ACCESS TO PANEL 194ER AND PERFORMED GVI OF THE LDG SELECTOR VALVE. DURING INSPECTION FOUND WIRES W108-00137-22 AND W108-00138-22 FOR PLUG P1246 OF THE LDG SELECTOR VALVE TO BE CHAFED AND CAUSING SHORT TO EACH OTHER.  SHORTED WIRES WERE CAUSING THE CB LG CMD TO TRIP RESULTING IN THE FAILURE OF THE LANDING GEAR. PERFORMED REPAIR ON CHAFED WIRING AND CLOSED ACCESS. JACKED THE AIRCRAFT UP AND PERFORMED OPS CHECKS OF THE LANDING GEAR. PERFORMED MULTIPLE LANDING GEAR RETRACT AND EXTEND CYCLES. OPS CHECKS WERE SATISFACTORY. DISCREPANCY NO LONGER STANDS. PLACED AIRCRAFT ON GROUND AND REMOVED JACKS. WORK PERFORMED IAW AMM 32-31-04.
