Finding a CASA LAME in Europe?
MAEHHH,
For private operations, there is nothing fundamentally stopping you.
I am aware that, in several cases (in which I have been involved) CASA has approved the use of a EASA Part 145 to carry out maintenance on a small VH- registered aircraft, based "temporally" in an EC country, and CASA gave approval for the owner/operator of the aircraft to produce and issue the Maintenance Release.
This was pre the McCormick era, so I am not so certain CASA would now be as accommodating, in exercising a sensible interpretation of their own rules.
Tootle pip!!
