Act of 1934, as amended (47 U.S.C. 312).
    (a) Expiration. Authorizations automatically terminate, without 
specific FCC action, on the expiration date specified therein, unless a

    (1) Authorizations do not terminate while a timely filed application 
for extension of the construction period is pending (see

    (2) If a timely filed application for extension of the construction 
period is dismissed or denied, the authorization automatically

action dismissing or denying the application for extension of the 
construction period.
    (c) Service discontinued. Authorizations automatically terminate, 
without specific FCC action, if service is permanently discontinued as

terminate, without specific FCC action, at the end of the period 
specified therein, except as provided in paragraph (d)(1) of this 
section, or upon failure to comply with the terms and conditions 
therein.
    (1) STAs do not terminate while a timely filed request for an 
extension of the STA term, in accordance with Sec. 22.125(b), is 
pending.
    (2) If a timely filed request for extension of the STA term is 
dismissed or denied, the STA automatically terminates, without specific
