Sec.  2.921   Hearing on application.

   Whenever it is determined that an application for equipment authorization
   presents substantial factual questions relating to the qualifications of the
   applicant  or  the  equipment (or the effects of the use thereof), the
   Commission  may designate the application for hearing. A hearing on an
   application for an equipment authorization shall be conducted in the same
   manner as a hearing on a radio station application as set out in subpart B
   of part 1 of this chapter.
