AIRJAE,
The Smart Cockpit link above is your best bet. It will provide you will a scanned PDF format of the ATR FCOM.
As for getting the actual ATR licensed CBT used for teaching Type Rating Courses - forget it. It is very expensive and strictly licensed (at a hight cost) to approved ATR Type Rating Training Organisations (TRTO's).
The CBT is very VERY detailed, so the FCOM is ideal if you just want to refresh your knowledge or do a bit of prep for an Initial Type Rating.
If anyone knows how to get your hands on the actual ATR CBT then I would be delighted to be proved wrong as I would LOVE to get my hands on it!!!
