**Read Full FAA Rule Release...Tracking


With respect to the procedures for aircraft owner and operator requests to block and unblock aircraft from inclusion in the FAA’s ASDI data feed, the FAA concludes as follows:

1. Requestors. The FAA will honor each written request of an aircraft owner and operator, submitted in accordance with paragraphs 2 and 3 to block or unblock their aircraft’s appearance in the FAA’s public ASDI data feed. Aircraft owners and operators may submit their request on their own behalf, or they may do so through a legally authorized agent, including an attorney or an aircraft management company with a fiduciary duty to carry out the owner’s or operator’s express wishes with respect to the aircraft.

2. Substance of Requests. To assist the FAA in processing aircraft owner or operator requests promptly, all requests related to an aircraft’s ASDI blocking or unblocking must include the following information:

  • The name of the requestor;
  • the registration number(s) of the aircraft to be blocked or unblocked;
  • a certification that the requestor is the owner or operator of the specified aircraft or is a legally authorized representative of the aircraft owner or operator;
  • a telephone number or electronic mail address to which the FAA can direct any questions about the request; and
  • for a request to block one or more aircraft, a statement indicating the requestor’s desired level of ASDI blocking—either at the FAA source or at the ASDI subscriber level.

3. Addresses. The FAA’s primary electronic mailbox for all aircraft blocking and unblocking requests and for related inquiries directed to the ASDI blocking program is The FAA also will accept aircraft block and unblock requests submitted by regular mail at: FAA ASDI Blocking Request; ATO System Operation Services, AJR-0; Wilbur Wright Building, Room 3E1500; 600 Independence Avenue SW; Washington, DC 20597.

4. FAA Monthly Implementation. The FAA implements the ASDI block list updates on the first Thursday of each month. As a result, requests that the FAA receives on or before the 15th of the preceding month are likely to be processed in time to take effect in the month after the FAA receives them. However, it is possible that the volume of requests in a given month, a requestor’s timeliness, or issues with the completeness and accuracy of the information that the FAA receives could preclude the FAA from processing some requests in time for them to take effect in the month following their submission. In that event, the FAA will process all requests in the order in which the FAA receives them, to the extent that it is possible.

5. FAA Treatment of Aircraft That Are Currently Blocked. Any aircraft that is currently on the ASDI block list, either by virtue of a certified security concern submitted after June 3, 2011, or a request submitted under the FAA’s interim ASDI block policy, will remain indefinitely on the ASDI block list when the policies in this document take effect. It is not necessary for the owners or operators of these aircraft to resubmit their requests, unless they wish to change the blocking status of their aircraft or amend the level at which their aircraft is blocked.

Issued in Washington, DC, on August 14, 2013.

J. David Grizzle,

Chief Operating Officer, ATO.
