The Transportation Security Administration (TSA) intends to propose new regulations to revise and standardize the procedures, adjudication criteria, and fees for most of the security threat assessments (STA) of individuals for which TSA is responsible. The scope of the rulemaking will include transportation workers who are required to undergo an STA, including surface, maritime, and aviation workers. TSA will propose fees to cover the cost of all STAs. TSA plans to improve efficiencies in processing STAs and streamline existing regulations by simplifying language and removing redundancies. As part of this proposed interim final rule (IFR), TSA will propose revisions to the Alien Flight Student Program (AFSP) regulations. TSA published an interim final rule for AFSP on September 20, 2004. TSA regulations require aliens seeking to train at Federal Aviation Administration-regulated flight schools to complete an application and undergo an STA prior to beginning flight training. There are four categories under which students currently fall; the nature of the STA depends on the student's category. TSA is considering changes to the AFSP that would improve the equity among fee payers and enable the implementation of new technologies to support vetting.
