I had vents in the D panel and the higher pressure in the back caused
some exhaust getting into the flap slots while going slow to enter the
cockpit. After performing a preflight on a Liberty (certificated Europa?)
I noted 2 openings on the bottom of the fuselage. Each had a reverse
scoop over it. I went back to my Europa. I already had an access door
under the fuselage for the gascolator. I pulled the door off approx 4"
X 5" and fashioned a reverse scoop out of fiberglass. In addition to
this I made better closure of the flap slots using rubber sheeting. The
results were noticeably better, using a CO monitor. I now only get a short
beep once in a while in the pattern rather than exceeding limits.

escape via the rear fuselage (trim tab slots). But now I've read that the
rear fuselage has a higher pressure than the cabin.

rather than trying to pressurize the cabin or to get oscillations in the
air? Any ideas or satisfying implementations?
