102-33.435—What CAS cost and utilization data must we report?
You must report the costs and flying hours for each CAS aircraft you hire. You must also report the costs and contractual periods for related aviation services that you hire (i.e., by contract or through an inter-service support agreement (ISSA)). Report related aviation services that you hire commercially in support of Federal aircraft as “paid out” Federal aircraft costs—do not report them as CAS. See the “FAIRS User's Manual,” available from GSA, Aircraft Management Policy Division (MTA), 1800 F Street, NW., Washington, DC 20405 for a complete description of the CAS data elements reportable to FAIRS.
