Thats very good of you, being prepared to get your hands dirty, however you might be a spanner monkey for longer than you think, having a basic ticket without type ratings means you will have to start as a grubby mechanic (providing of course you can get a job ) and be prepared to monkey about for quite some time before you get type rated, sadly even when you reach the dizzy heights of a type rated engineer you will especially if you want to work on the line be expected to do your own spanner monkeying, ...welcome to the real world
