Sec. 23.28  Special temporary authorization.

    (a) Requests for special temporary authority must be accompanied by 
a showing that interference will not be caused to the fixed public or 
fixed public press service for which the station is primarily licensed; 
and, in addition, such requests must be accompanied by the following:
    (1) A statement of the call signs, location, and frequencies of the 
transmitting station; The call signs, location, and frequencies of the 
received station; and the type or types of emission to be employed by 
both stations.
    (2) A statement as to whether the frequencies are to be used for 
contact control purposes only.
    (3) A statement of the period for which the temporary authority is 
desired.
    (4) A statement describing the service which is to be rendered.
    (b) Temporary authorizations of operation not to exceed 180 days may 
be granted under the standards of section 309(f) of the Communications 
Act where extraordinary circumstances so require. Extensions of the 
temporary authorizations for a period of 180 days may also be granted, 
but the renewal applicant bears a heavy burden to show that 
extraordinary circumstances warrant such an extension.
    (c) Each application proposing construction of one or more new 
antenna structures or alteration of the overall height of one or more 
existing antenna structures, where FAA notification prior to such 
construction or alteration is required by part 17 of this

chapter, must include the FCC Antenna Structure Registration Number(s) 
for the affected structure(s). If no such number has been assigned at 
the time the application(s) is filed, the applicant must state in the 
application whether the owner has notified the FAA of the proposed 
construction or alteration and applied to the FCC for an Antenna 
Structure Registration Number in accordance with part 17 of this 
chapter. Applications proposing construction of one or more new antenna 
structures or alteration of the overall height of one or more existing 
antenna structures, where FAA notification prior to such construction or 
alteration is not required by part 17 of this chapter, must indicate 
such and, unless the structure is 6.10-meters or less above ground level 
(AGL), must contain a statement explaining why FAA notification is not 
required.
