I found a hole from the interior of the plane into the parachute storage area. And the parachute storage area is not sealed tightly most likely because the top has to blow off. Anyway that little hole in the back of the compartment concerned me that the warm air from the interior of the plane would leak into it and out. So I plugged it. I made sure it is smooth on the inside so the parachute would not catch on it. Not in the pictures below but I ended up adding some filler over top of it and seeing it down to make it super smooth.
