## Discrepancy

AFTER DEPARTING, PILOT, SELECTING GEAR UP.  AFTER THIS THE PILOT NOTED A STRONG ELECTRICAL BURNING SMELL.  THE PILOT ELECTED TO RETURN TO DEPARTURE.  ON VERY SHORT FINAL APPROACH, THE PILOT NOTED THE GEAR WAS NOT FULLY LOCKED INTHE DOWN POSITION AS INDICATED BY THE GEAR HANDLE LIGHTS AND INITIATED A GO AROUND AND DECLARED AN EMERGENCY.  BY THAT TIME THE BURNING SMELL HAS DISIPATED SOMEWHAT.  THE PILOT THEN HAND-PUMPED THE GEAR DOWN AND LANDED WITHOUT INCIDENT.  A MAINTENANCE EVALUATION REVEALED THE HYDRAULIC MOTOR THAT DRIVEWS THE GEAR HAD FAILED RESULTING IN THE BURNING SMELL. THE MOTOR WAS REPLACED AND THE AIRCRAFT HAS BEEN PLACED BACK IN SERVICE.  (K)
