I don't work with Pavehawks, but I do work with Army Blackhawks. I can get you some pictures of what is underneath the Pilot and Co-Pilot seats if you post your e-mail. I can't imagine there is too much of a difference. I can tell you that on the Army Hawks this area is typically covered with a thin black plastic material to prevent debris from getting in the area, however this plastic often ends up falling down into the area itself.
