If the court orders the appointment of a trustee or an examiner, if a trustee or an examiner dies or resigns during the case or is removed under
section 324 of this title, or if a trustee fails to qualify under
section 322 of this title, then the United States trustee, after consultation with parties in interest, shall appoint, subject to the court’s approval, one disinterested person other than the United States trustee to serve as trustee or examiner, as the case may be, in the case.
