Pop quiz, what do we all think the current sanction should be for penning up 757s without actually doing a tool check?
I can't comment as towards how the service would deal with this using today's standards of disciplinary measures, but I can let you know how it's dealt with at my place at least.
Each mechanic or avionic type gets their own personal toolkits with an e-key which become their own responsibility. At the end of each shift, they are responsible for confirming using their electronic certifying stamp that the kit is complete. To back up the e-system, we brought in an integrity check by delegating an independent checker who would confirm to the tool kit owner that all tools are indeed there before the stamp is set.
Every day, the tool kit owner must authorise their e-key and if they hadn't stamped in the system the previous day, their tool kit remains locked. This is then flagged to their team leader who then commands a full tool kit check and reauthorises the e-key. Self discipline soon kicks in with the team leader normally only re-authing the e-key after periods of absence (leave etc).
For persistent offenders, monitoring is performed with a manager overseeing their daily tool checks for a prescribed time frame derived from the quality department of the company. Further transgressions lead to an informal warning, then to a formal warning and potential dismissal.
Lost tools are generally traced very quickly as we can cross refer the job cards allocated to a person with the aircraft and the area they were working in. So it's a system that promotes responsibility and redresses any failures quickly and with little fuss for minor transgressions while providing maximum traceability should a missing tool report occur.
