The DOT Office of Inspector General plans to begin an audit of the FAA’s initiatives to address ATC staffing levels on September 7. For years, various groups have expressed concern that some ATC facilities are either under- or over-staffed. “However, determining the extent of those imbalances is problematic,” said the IG office, because staffing is affected by a number of issues. “The FAA’s success at achieving a balanced workforce will largely depend on actions it takes to address these factors.” Dealing with ATC staffing issues expediently is particularly critical as the FAA is facing attrition of nearly half its current controller workforce between fiscal years 2005 and 2012.
