OIG recommends that the Aviation Governing Board (AGB), in coordination with the Bureau of International Narcotics and Law Enforcement Affairs (INL), revise Volume 2 of the Foreign Affairs Manual (FAM) 800 to clarify that INL is the sole provider of aviation services for the Department of State and any requests for exceptions to, or waiver of this policy, along with a written justification, must be submitted to and approved by the AGB. The FAM revision should include a requirement for a periodic review of the decision to determine whether it remains beneficial.
