Washington (CNN)Maintenance of explosive detecting scanners and x-ray machines at the U.S. airport security checkpoints are not being managed properly, according to a new government report. And the Department of Homeland Security can't even definitively say they are all working properly.
- TSA has not given airports guidance on how to track and monitor preventative maintenance;
- TSA relies on self reported data from maintenance contractors and does not validate the data to confirm the necessary maintenance has been completed;
- TSA cannot be certain maintenance has been completed because the contractor provided data report is incomplete;
- There is also no TSA enforced penalty the agency can levy against the contractor if it does not perform preventative maintenance as required.
