## Discrepancy

DURING TAKEOFF, DURING A POST MAINTENANCE TEST FLIGHT, THE NOSE LANDING GEAR FAILED TO RETRACT. THE CREW REPORTED SELECTING GEAR UP, THEN HEARING A LOUD BANG WHILE THE GEAR WAS IN TRANSIT. THE NOSE GEAR THEN SHOWED DOWN AND LOCKED WITH THE MAINS RETRACTED. THE CREW ELECTED TO RETURN TO THE AIRPORT IMMEDIATELY AND PROCEEDED TO PERFORM A NORMAL LANDING.  MAINTENANCE DISCOVERED THAT THE DRAG STAY PICKUP ON THE NOSE LANDING GEAR HAD BROKEN OFF AT THE NLG ACTUATOR ATTACH FITTING. THIS CAUSED A COMPLETE SEPARATION OF THE NLG ACTUATOR FROM THE NLG ASSEMBLY.
