The Air Force Has Not Compared Costs of Alternative Ways To Replace CT-39 Aircraft

Pursuant to a congressional request, GAO attempted to verify: (1) the projected cost savings associated with the lease of replacements for CT-39 aircraft, (2) the cost to phase out the existing CT-39 fleet, and (3) the personnel savings from converting to contract maintenance. Further, GAO commented on the prudence of leasing replacement aircraft in lieu of purchase.
