LAME technically qualifies as a para-professional qualification, trade qualifications are for an AME (CERT IV) (hence the required diploma level qualification for LAME). Interestingly the Diploma in Aeroskills (LAME qual) involves more teaching hours (and thus knowledge) than any other diploma level qualification in Australia, and more than many Bachelor degrees.
Progressive,
Creampuff has dealt with the issue of the standing of the log book statement.
The above may well be true, but, interestingly, the present setup is far lower teaching hours than a number of other countries, and you may be aware of the current criticism of the product of the present system.
Likewise, it is not unusual for unskilled person or tradesmen to earn far more then "professionals".
None of that has any bearing on the industrial classification, which come from the industrial relations system.
Tootle pip!!
