## Discrepancy

LT PROPELLER DIDN`T UNFEATHER ALL THE WAY WHEN TAKING THE RUNWAY.  LT PROPELLER APPEARS UNFEATHERED (NORMAL STATUS LIGHTS).  WHEN ADDING POWER FOR TAKEOFF, LT PROPELLER FEATHERED ITSELF.  ON TAXI BACK TO THE GATE, PROP REMAINED IN FEATHER.  REMOVED AND REPLACED THE LT P3 SWITCH, OPS CHECK GOOD.
