## Discrepancy

FOLLOWING NORMAL DEPARTURE, CREW ATTEMPTED TO RETRACT THE LANDING GEAR. THE LANDING GEAR SELECTOR SWITCH COULD NOT BE MOVED FROM THE DOWN POSITION TO THE UP POSITION. CREW FLEW UNTIL ENOUGH FUEL WAS CONSUMED SO A NORMAL WEIGHT LANDING COULD BE ACCOMPLISHED. THE SWITCH WAS EXAMINED AND IT WAS DETERMINED THAT RECENTLY THE SWITCH HAD BEEN TIGHTENED BY MAINTENANCE PERSONNEL DUE TO THE WHEEL PORTION OF THE SWITCH WIGGLING ON THE SWITCH BAT. SLIGHT LOOSENING OF THE SET SCREW THAT ATTACHES THE WHEEL TO THE SWITCH BAT RESULTED IN NORMAL OPERATION OF THE SWITCH
