WASHINGTON (AP) — The Transportation Security Administration is tightening security rules for aviation workers months after a baggage handler in Atlanta was accused of smuggling guns aboard commercial aircraft.

Homeland Security Secretary Jeh (jay) Johnson says new security measures will include real-time, recurring background checks for aviation workers, including airline workers. It will also include a fingerprint-based check of criminal history records every two years for airport employees who hold Secure Identification Display Area badges.

Airport and airline workers traveling as passengers will also have to go through TSA screening before boarding a flight.

Johnson says the changes follow a 90-day review of aviation security in the wake of the arrest of an airline baggage handler accused of helping smuggle guns onto passenger jets to New York City.
