Pull two hinge pins at the bulkhead, and it drops down and comes out the baggage door.
If you are slow, maybe 15 seconds??
The two orange things in the photo are flags on the temp hinge pins I am using, they are inserted from the center toward the sides.
I like these
wire markers, used by utility companys and such, they make good test pins, and the flag makes it easy to find them when you drop one on the floor.
