Sec. 2.939  Revocation or withdrawal of equipment authorization.

    (a) The Commission may revoke any equipment authorization:
    (1) For false statements or representations made either in the 
application or in materials or response submitted in connection 
therewith or in records required to be kept by Sec. 2.938.
    (2) If upon subsequent inspection or operation it is determined that 
the equipment does not conform to the pertinent technical requirements 
or to the representations made in the original application.
    (3) If it is determined that changes have been made in the equipment 
other than those authorized by the rules or otherwise expressly 
authorized by the Commission.
    (4) Because of conditions coming to the attention of the Commission 
which would warrant it in refusing to grant an original application.
    (b) Revocation of an equipment authorization shall be made in the 
same manner as revocation of radio station licenses.
    (c) The Commission may withdraw any equipment authorization in the 
event of changes in its technical standards. The procedure to be 
followed will be set forth in the order promulgating such new technical 
standards (after appropriate rulemaking proceedings) and will provide a 
suitable amortization period for equipment in hands of users and in the 
manufacturing process.
