After overcoming some procedural blocks, the Senate began consideration on Thursday of legislation reauthorizing the Federal Aviation Administration (FAA). Some 100 amendments have been introduced and more are expected, however, it is anticipated that action on the measure could be completed as early as the end of next week. Extraneous issues such as the extension of several expired tax provisions could slow things down but compromises are being worked out to keep the legislation on track. The nearly two-year authorization provides a $400 million increase in 2017 for the Airport Improvement Program (AIP) but does not lift the volume cap on the Passenger Facility Charge (PFC) program. The AIP and PFC are the main funding and financing mechanisms for airport and runway infrastructure projects.
