An investigation is under way after dozens of bag-scanning security staff at Birmingham Airport were found to have missed vital training.
At least two managers were sacked by contractor Mitie for "allowing untrained staff" to screen luggage before it was loaded onto aircraft.
The managers were accused of falsifying training records and failing to supervise exams, but one told the BBC he had been made a scapegoat.
Mitie said workers had been retrained.
The Civil Aviation Authority (CAA) is understood to be investigating the allegations, which relate to about 40 out of 120 Mitie staff members.
The ground security operatives, who screen hold luggage that is checked in by passengers, failed to attend refresher training they are required to do every 13 months.
