20 Pa. C.S. § 3183
The court on its own motion may, and on the petition of any party in interest alleging adequate grounds for removal shall, order the personal representative to appear and show cause why he should not be removed, or, when necessary to protect the rights of creditors or parties in interest, may summarily remove him. Upon removal, the court may direct the grant of new letters testamentary or of administration by the register to the person entitled and may, by summary attachment of the person or other appropriate orders, provide for the security and delivery of the assets of the estate, together with all books, accounts and papers relating thereto. Any personal representative summarily removed under the provisions of this section may apply, by petition, to have the decree of removal vacated and to be reinstated, and, if the court shall vacate the decree of removal and reinstate him, it shall thereupon make any orders which may be appropriate to accomplish the reinstatement.
