Tony Webster filed this request with the Federal Aviation Administration of the United States of America.


From: Tony Webster

To Whom It May Concern:

This is a request under the Freedom of Information Act. I hereby request the following records:

(1) Any and all lists of aircraft blocked, hidden, or limited from any data feeds;
(2) Any and all requests to hide, block, obscure, or limit access to aircraft registration records, location data, ASDI feeds, ADS-B data, or air traffic control feeds;
(3) Any current, or the most recent, list of aircraft on the Block Aircraft Registration Request (BARR List), also known as FAA Source Blocking; and
(4) Any current, or the most recent, list of aircraft on any Aircraft Situation Display to Industry (ASDI) or National Business Aviation Association (NBAA) subscriber-level blocking lists, also known as ASDI Block or NBAA Block.

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 20 business days, as the statute requires.

Good Morning Mr. Webster,

I am the coordinator that will be responding to your FOIA request #2017-004706. After reviewing your request, I feel that clarification is necessary.

1. The FAA only has one blocked at industry and blocked at the source block lists (Formerly the BARR, now the ASDI Block). This means you will be getting 1 list as you are essentially asking for the same thing three times (1, 3, and 4). You also need to specify whether you want the blocked at industry list or blocked at the source. If you want both, the blocked at industry has both industry and source blocks.

2. The FAA does not limit access to aircraft registrations as they are publically available on the FAA's website when you search by aircraft N number.

3. If you want the FAA to search email or letters for requests to block an aircraft, please be advised that you will accrue fees for the amount of time it takes to search and review every record. This could mean a 5-10 hour search time. 2 hours would be free, after that you are responsible for all search and review fees at the rate of $63 per hour. You will have to agree to pay this before search is initiated or you can amend your request to specify a specific date range. Please note, the larger the date range, the larger the search and review time.

4. We can provide you with generic information for requests to be added to the block list such as company, date requested, date added and date removed for a specific time frame. This will likely fall within the 2 hour search range and you will not accrue fees.

Please let me know by the 15th whether you would like to amend your request, withdraw your request, or proceed with the original request with acknowledgement and acceptance of the fee estimate.

Thank you,
