I don't think that many people here realize how much an experienced A&P can make. The guy that works on our plane is paid as much as the Captains that fly it, and he doesn't have to spend 40 hrs a week to work on it. When he is not working on our plane, he is contracting himself out at $500 day. I personally think he works too much for his own good, as he probably works 6 days a week, but he makes serious money.
I know it is not possible for every A&P to do this. Our guy has years of experience working on biz jets and has a good reputation in a busy area, but I was still supprised by how much he makes.
I personally want to get my A&P, mostly so I could work on a personal airplane. I figure it would be a fun hobby and a good way to cut the cost of ownership, assuming I ever have enough to buy an older airplane. It is kind of hard to fit in the A&P school when you work as a pilot though, so I will probably have to wait until I retire.
