About starting a Business in the Military...?

Well I'm in the Air Force, and I plan on opening my own small business...I've also heard from word of mouth that if I start a small business and I make more than 60% of my base pay, that I could get an honorable discharge and just use my time for my business...If you know anything about this please answer it, or what would be more helpful is if you know an AFI or DOD that states this it would help me out alot. Another thing is that if you could clarify any misunderstandings about this question...Thanks alot
