Could I get in trouble for this?

I was looking around on the net and found a free download of the ATSG A-500/42RH manual. If I share this information in a public forum, will that get me into legal trouble? There are many more trans manuals and info there, but if this is copyright protected info, I don't want to get thrown in jail trying to help out my fellow automotive enthusiasts.

To be clear, I never put this info there, I just found it. Not sure if I'm even going to download it. Any thoughts?

You are in big trouble, young man. Consider yourself grounded!
That's about all the trouble you can get into.
