## Discrepancy

ON GROUND RUN, RT PROP WOULD NOT FEATHER.  OTHER PITCH CHANGE FUNCTIONS WORKED NORMALLY.  INITIALLY THE PROP WAS REPLACED WITH SIMILAR RESULTS THE GOVERNOR WAS THEN REPLACED WITH A SERVICEABLE UNIT FROM ANOTHER AIRCRAFT AND THE PROP PITCH/FEATHER FUNCTIONED NORMALLY.  THE SUSPECT GOVERNOR WILL BE SENT FOR ANALYSIS AND LIKELY OVERHAUL.
