Sec. 25.116  Amendments to applications.

    (a) Unless otherwise specified, any pending application may be 
amended until designated for hearing, a public notice is issued stating 
that a substantive disposition of the application is to be considered at 
a forthcoming Commission meeting, or a final order disposing of the 
matter is adopted by the Commission.
    (b) Major amendments submitted pursuant to paragraph (a) of this 
section are subject to the public notice requirements of Sec. 25.151. An 
amendment will be deemed to be a major amendment under the following 
circumstances:
    (1) If the amendment increases the potential for interference, or 
changes the proposed frequencies or orbital locations to be used.
    (2) If the amendment would convert the proposal into an action that 
may have a significant environmental effect under Sec. 1.1307 of this 
chapter.
    (3) If the amendment specifies a substantial change in beneficial 
ownership or control (de jure or de facto) of an applicant such that the 
change would require, in the case of an authorized station, the filing 
of a prior assignment or transfer of control application under section 
310(d) of the Communications Act, provided however, that the change 
would not be considered major where it merely amends an application to 
reflect a change in ownership or control of the station that had been 
previously approved by the Commission.
    (4) If the amendment, or the cumulative effect of the amendment, is 
determined by the Commission otherwise to be substantial pursuant to 
section 309 of the Communications Act.
    (c) Any application will be considered to be a newly filed 
application if it is amended by a major amendment (as defined by 
paragraph (b) of this section) after a ``cut-off'' date applicable to 
the application, except under the following circumstances:
    (1) The amendment resolves frequency conflicts with authorized 
stations or other pending applications but does not create new or 
increased frequency conflicts;
    (2) The amendment reflects only a change in ownership or control 
found by the Commission to be in the public interest and, for which a 
requested exemption from a ``cut-off'' date is granted;
    (3) The amendment corrects typographical, transcription, or similar 
clerical errors which are clearly demonstrated to be mistakes by 
reference to other parts of the application, and whose discovery does 
not create new or increased frequency conflicts; or
    (4) The amendment does not create new or increased frequency 
conflicts, and is demonstrably necessitated by events which the 
applicant could not have reasonably foreseen at the time of filing.
    (d) Any amendment to an application shall be signed and submitted in 
the same manner, and with the same number of copies, as was the original 
application.
