I read a story on this today in ATW news. The short version is that the house of reps adjourned it's session without resolving the FAA funding issue and won't be back until September. The Senate can authorize a stopgap measure if they desire, but this measure would automatically cut funding to essential air service appropriations favored by many senators. Gridlock in congress...
Meanwhile, some 4,000 non-critical FAA employees remain on furlough and an estimated 70,000 government contract workers involved in airport improvement projects are idled. Additionally, the FAA is no longer authorized to collect airport fees and taxes estimated to total a Billion dollars a month.
ATC and safety inspectors continue to report for work.
The Senate may vote on another stopgap by the end of the week. The FAA has been operating on stopgap funding since 2007.
