On May 5, 2010, the Department of Homeland Security began requiring aircraft operators to check no-fly lists within a two-hour time frame after changing its no-fly list update policies as a result of the Times Square Plot. The Transportation Security Administration (TSA) will require aircraft operators to check the no-fly list within two hours of being electronically notified of additions or changes. Previously, aircraft operators were required to re-check the list within 24 hours.
Currently, the TSA general aviation principal security inspectors are reaching out to the general aviation community to ensure that aircraft operators are aware of these new policy updates.
