I have been busy packing and getting ready to fly up to Oshkosh, I leave tomorrow by Cherokee 140. I did get a little more done on the rear bulkhead alteration, one can see the nature of the cutout to allow an annual condition inspection without removing the fuel tank and lines. There are many ways to accomplish this, shown is the way I chose to do it. Still got to put in some nutplates, hope to pick up some at Oshkosh to save shippingl.
