I'm with you Horatio, It doesn't need to be this difficult.
When we first became a Part 142, I ended up putting in a Significant Change Request to change the process for making Significant Changes! The process to make what we would normally call a "small" change required a full on risk assessment, a formal assessment of the risk assessment by the change management committee, send off the change to CASA and wait for them to approve the change. Minimum turn around was about 4 weeks with one change taking just on 12 months for a change of address. Yes a change of address is considered a Significant Change requiring CASA approval before you can pack up your desk and move to the new building you are probably paying rent on waiting for CASA to approve....
Over and out.....
