The Transportation Security Administration (TSA) has failed to identify 73 aviation workers with potential links to terrorism, a report by the US Department of Homeland Security (DHS) has revealed.
The 'TSA Can Improve Aviation Worker Vetting' report follows another DHS investigation where the Homeland Security officials could get banned items passed through security checks.
According to DHS, these individuals, who were working for major airlines, airport vendors and other employers, could not be identified as the TSA does not have access to the complete terror watchlist.
The audit also found that thousands of the required biographical records held by the TSA were either missing or incomplete and it was using data sent by airports to vet more than two million aviation workers.
The report said: "TSA did not have an adequate monitoring process in place to ensure that airport operators properly adjudicated credential applicants' criminal histories."
The files inspected revealed that around 1,500 records contained only first initials of the employees, while 14,000 immigrants had no alien registration number and 75,000 lacked passport number.
The files of around 87,000 employees had no social security number.
DHS has recommended TSA to request and review additional watchlist data, to ensure that airports improve verification of applicants' right to work and revoke their credentials once their right expires.
The department has also asked TSA to improve its quality of vetting data.
