## Discrepancy

LANDING GEAR WOULD NOT RETRACT DURING CLIMBOUT, WHEN CREW WAS RETURNING FOR LANDING, GPWS GAVE (TO LOW GEAR) ALERT.  THE CREW THEN INITIATED A GO-AROUND, ASKED TOWER TO CONFIRM, THREE GEAR DOWN, DID CONFIRM.  CREW DECLARED EMERGENCY, MADE NORMAL LANDING, DURING TAXI, DISCOVERED NOSE WHEEL STEERING WAS INOPERATIVE.  MAINTENANCE TO VERIFY DISCREPANCY, GEAR RETRACTED CORRECTLY.  FURTHER TROUBLESHOOTING COULD NOT GET GEAR TO FAIL TO OPERATE WHILE ON JACKS.  REPLACED LT OB MAIN GEAR SQUAT SWITCH, DUE TO SUSPECTED WATER INGRESSION, CHANGED LANDING GEAR CONTROL HANDLE AND LT LANDING GEAR CONTROL CIRCUIT BREAKER, PRECAUTIONARY ACTION.  AC WAS RELEASED AND OPS CHECK FLIGHT WAS PERFORMED WITH NO FURTHER DEFECTS NOTED.
