I also did the most recent L1 course, and although been maintaining for 500hrs plus, found it useful and open enough to share experiences of different types and methods.
Remember an L1 authority allows self maintenance on ALL aircraft not just the one you know or built.
Course exposed me to fabric repair, other braking systems, taildraggers, IO engines and other things I would have never dealt with otherwise - BUT technically had the rights to service and repair if required
If nothing else, it provided reality check on self abilities and the need to NOT repair something you don't understand or get help.
If you reckon any std CFI is up to this level of training think again. Goes well beyond daily checks.
More people no longer maintain cars and less frequently see problems so assuming they can look after an aircraft properly or know what a healthy engine sounds like is unrealistic. For many it would be the first carb fed engine they have ever started.
Yes a bit of it is about responsibilities and the required paperwork but rest was practical and hands on. Nice book on it all too.
The current situation with the online course being adequate is temporary until many more courses have been done and framework out there to conduct training.
In time, to maintain your own aircraft you will need BOTH online and practical courses. Likely also to need currency or upskilling records too. As per many other competency based training.
There was apparently promised, to CASA, in writing, from a way former RAA chief that RAA would conduct practical training to keep the LAME maintenance exemption going.
It hadn't been doing any seriously, no records (and no one knew about it) so pressure is there to do it.
