Think I'd be worried also .. the 737 is an old certification so one should really research the TC basis .. however, for the purposes of your question, the current requirements are probably a good place to start .. check
25.631 and
25.775
Unfortunately, the PC I'm on at the moment has a high security setting so I can't download the TCDS ... but you might check out TCDS A16WE at the
FAA site
