Concerned with the FAA’s recent history of cost and schedule overruns in acquiring equipment to update ATC, as well as shortfalls in that equipment’s performance, DOT’s inspector general (IG) is auditing the agency. The objective of the IG’s investigation is to ensure that Congress and the agency are able to meet the growing demand for air traffic services and get the most bang for the taxpayers’ buck. The IG is particularly concerned now with the FAA’s ability to meet demand because it has requested less money for ATC modernization than it did last year, and has canceled or deferred several projects.
