## Discrepancy

ON CLIMB OUT AFTER TAKEOFF,  AT APPROXIMATELY 500 FT AGL, THE RT ENGINE PROPELLER WENT TO A FULL FEATHER.  ENGINE SHUTDOWN AUTOMATICALLY AND ONE ATTEMPT TO RESTART WAS MADE WITH NO SUCCESS.  A LANDING WAS EXCUTED WITHOUT INCIDENT.  SUSEQUENT GROUND INSPECTION REVELED OIL LEAKAGE AROUND PRO HUB.  1G4 IS REMOTE AND ALL MAINTENANCE WILL TAKE MORE TIME THAN USUAL.  PROPELLER WILL BE REMOVED,  INSPECTED AND REPAIRED.  DEFINITIVE CAUSUAL FACTORS WILL BE DETERMINED AT REPAIR FACILITY.  SUSPECTED SEAL OR CONTROL ARM DEFECT AT THIS TIME AFTER VISUAL INSPECTION.
