Is bachelors in aircraft maintenance engineering good choice and what can one do after completing in jobs and masters ( MBA ).

Personally, I find that all fields tend to overlap to some degree, and that branching out to other areas of knowledge give you added insight in solving any problems. If you have a degree in engineering and cover the areas of engineering of all types -- electrical, mechanical, computer, chemical, biological -- to any degree beyond what's required -- you'll have a great edge in getting jobs. And since you'll always be concerned with how to facilitate any project or business or entrepreneurial venture or even charity -- an MBA is invaluable. Remember -- you can always get more done in a team, and business is essentially the science of getting people what they want.

The thing you need to realize is the extreme overlap between engineering disciplines. If you can achieve a bachelors in aircraft maintenance, you'll likely be doing a lot of mechanical and computer engineering anyway. Having knowledge of aeronautics and electronics will come in handy as well. You really can't go wrong. Another thing is the continuous evolution of technology, so you'll have to keep up to speed on current developments anyway. This would mean that you could focus on other areas just about anytime and learn more in whatever specialties you're interested in pursuing. Also, many companies will provide more training and education for you to learn about anything that they deem to be required by their particular projects. If you're into engineering in the first place, this will be more fun than a chore. Note I didn't day "than work" -- in my experience, I've found that I would gladly do for fun what I got paid to do at work. If you have an engineering bent, you'll be pretty much unable to resist a lot of very valuable topics. Like the saying goes -- do for work what you'd do for play and never work another day. I've found it to be true. Most of my inventions were originated when I was just "playing around", as it were :-)

Firstly, you need to understand how much overlap there is between engineering disciplines. Your studying in aircraft maintenance or anything in aeronautics or engineering in general will be applicable to any engineering position.
