14 CFR §121.905

1. (a)Each certificate holder that claims that AQP information or data it is submitting to the FAA is entitled to confidential treatment under 5 U.S.C. 552(b)(4) because it constitutes confidential commercial information as described in 5 U.S.C. 552(b)(4), and should be withheld from public disclosure, must include its request for confidentiality with each submission.
2. (b)When requesting confidentiality for submitted information or data, the certificate holder must:
   1. (1)If the information or data is transmitted electronically, embed the claim of confidentiality within the electronic record so the portions claimed to be confidential are readily apparent when received and reviewed.
   2. (2)If the information or data is submitted in paper format, place the word “CONFIDENTIAL” on the top of each page containing information or data claimed to be confidential.
   3. (3)Justify the basis for a claim of confidentiality under 5 U.S.C. 552(b)(4).
