## Discrepancy

THE LEFT MAIN GEAR WOULD NOT RETRACT AFTER TAKEOFF FROM TNN.  CREW SELECTED THE LANDING GEAR DOWN AND ALL THREE GEAR INDICATED DOWN AND LOCKED.  THE AIRCRAFT RETURNED TO TNN AND LANDED WITHOUT INCIDENT.  MAINTENANCE COULD NOT DUPLICATE THE PROBLEM WITH THE AIRCRAFT ON JACKS.  THE PROBLEM ONLY OCCURRED IN FLIGHT.  THE LEFT GEAR RETRACT ACTUATOR AND SYSTEM CHECKED NORMAL ON THE GROUND.  FLIGHT TEST WAS CONDUCTED WITH SYSTEM WORKING NORMAL.
