If any fiduciary fails to file in the court of probate having jurisdiction of the estate of a deceased person an inventory and appraisal as required, within the time limited, the court may cite such fiduciary to appear at a time and place therein stated and show cause why he should not be removed. Unless sufficient cause is shown and an inventory and appraisal is forthwith filed, the court shall remove such fiduciary and appoint a successor to complete the administration of such estate.
