## Discrepancy

AFTER TAKEOFF OF FLIGHT NR 3387 LANDING GEAR WOULD NOT COMPLETE ITS RETRACTION CYCLE.  INTRANSIT LIGHT STAYED ON WITH HYDRAULIC PUMP RUNNING CONTINUOUSLY.  GEAR EXTENDED NORMALLY.  AIR RETURN TO CWA.  MAINTENANCE FOUND NOSE UPLOCK SWITCH TO BE ADJUSTED RIGHT AT ACTUATION POINT.  ADJUSTED UPLOCK SWITCH IAW SAAB MM 32-61-15.  OPS CHECK GOOD.
