# §73.3578. Amendments to applications for renewal, assignment or transfer of control.

- (a) Any amendments to an application for renewal of any instrument of authorization shall be considered to be a minor amendment. However, the FCC may, within 15 days after filing of any amendment, advise the applicant that the amendment is considered to be a major amendment and therefore is subject to the provisions of [§ 73.3580](/cfr/47/73.3580.md).
- (b) Any amendment to an application for assignment of construction permit or license, or consent to the transfer of control of an entity holding such a construction permit or license, shall be considered to be a minor amendment, except that any amendment which seeks a change in the ownership interest of the proposed assignee or transferee which would result in a change in control, or any amendment which would require the filing of FCC Form 2100 Schedules 314, 315, or 345 (see [§ 73.3500](/cfr/47/73.3500.md)), if the changes sought were made in an original application for assignment or transfer of control, shall be considered to be a major amendment. However, the FCC may, within 15 days after the acceptance for filing of any other amendment, advise the applicant that the amendment is considered to be a major amendment and therefore is subject to the provisions of [§ 73.3580](/cfr/47/73.3580.md).
