Kevin Louis Thompson appeals the decision of the Merit Systems Protection Board, which upheld his removal by the United States Department of the Air Force from the position of civilian Air Traffic Control Specialist (Terminal) for failure to maintain an Air Traffic Control Specialist (ATCS) certificate as required by Air Force Instruction 13-203 (AFI 13- *407 208) and 14 C.F.R., Part 65, Subpart B (14 C.F.R. § 31, et seq.). He argues that the board erred as a matter of law because under Subpart B, he is not required to hold an ATCS certifícate, but rather an Ah* Traffic Control Tower Operator certificate (CTO). He also argues that the ATCS requirement in AFI 13-203 is a fabrication counter to law, thus inherently in bad faith and patently unfair. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(9).

This court must affirm a decision of the Merit Systems Protection Board unless the decision is (1) arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law; (2) obtained without procedures required by law, rule, or regulation having been followed; or (3) unsupported by substantial evidence. 5 U.S.C. § 7703(c). Because the decision of the board met these requirements, we affirm.

Thompson does not contest that he lost his ATCS certification. Instead, he argues that AFI 13-203, which required him to have this certification, was in bad faith and patently unfair. At the time of his removal, AFI 13-203 Paragraph 14.1 read: “In accordance with the Code of Federal Regulations 14, Part 65, Subpart B, Air Traffic Control Tower Operators, only personnel holding a current Air Traffic Control Specialist (ATCS) Certificate shall be authorized to perform air traffic control duties in USAF facilities.” It further states: “Additionally, each individual must satisfactorily complete the FAA CTO written test or hold an FAA CTO certification.” Subpart B however requires only the CTO certificate, stating that “[n]o person may act as an air traffic control tower operator at an air traffic control tower in connection with civil aircraft unless he ... [hjolds an air traffic control tower operator certificate issued to him under this subpart.” 14 C.F.R. § 65.31(a). The discrepancy can be accounted for because the Federal Aviation Administration has expressly granted permission to the military to add extra requirements in addition to those stated in Part 65 in FAA Order 7220.1A, chapter 1, paragraph 9. Thus, the Air Force was legally entitled to require Thompson to hold a current ATCS certificate in addition to the requirements of Subpart B, and AFI 13-203 was not a fabrication. Without evidence that the Air Force had acted in bad faith or patently unfairly, the board deferred to the Air Force.
