Lewy you go for it bonny lad I am a qualified motor technician and also a full unrestricted easa b1 licensed eng and I know that I would be rather doing aeroplane work than scrabbling around cars most machanics earn about 20,000 whereas if you become a licensed eng you could earn about 50k a year. I made the switch about 16 years ago and would never go back, but it`s a lot of hard work
