Maybe if CASA would allow a company to send over a LAME's licence number and have them confirm his licence might help a great deal, however they dont and wont do that due to "privacy issues".
Anybody with a scanner, PC, printer and time on their hands can easily fake a licence, when they bring in Photo licences and allow cross referencing through CASA then things will change.
Blaming management is one thing, but how many people actually knew and worked with these fake's, and why didn't they know he was full of it. Hell after 30 years in the industry I knew what courses all my mates were doing, what they had done and where they stood, to have any one of them suddenly announce that they were a LAME would have surprised everybody. Where was the vigilance on the hangar floor? as opposed to the Managers sitting inside Aircon offices who wouldn't know the guy from a bar of soap.
Just a though for what it's worth
