Sec. 22.315  Duty to respond to official communications.

    Licensees in the Public Mobile services must respond to official 
communications from the FCC with reasonable dispatch and according to 
the tenor of the communication. Failure to do so may be considered by 
the FCC to reflect adversely on a carrier's qualifications to hold FCC 
authorizations, and may also create liabilities for other sanctions.
    (a) Any person receiving official notice of an apparent or actual 
violation of a federal statute, international agreement, Executive 
Order, or regulation pertaining to communications shall respond in 
writing within 10 days to the office of the FCC originating the notice. 
If a response can not be sent within 10 days, an acknowledgement shall 
be sent, followed by a response as soon as possible explaining the 
reason for the delay.
    (b) Responses to official communications must be complete and self-
contained without reference to other communications unless copies of 
such other communications are attached to the response.
