I am assembling an RV-9 QB and have a few questions that I can't find answered in the drawings or build manual. The questions might have been answered there and I overlooked them.
I have a few parts that I am unsure where they are used. I've searched the fuselage drawings and manuals but cannot find where they are called out. In the inventory they are listed
AN Spacer, 4D 4 ea
AN837-4D 45 degree Bulkhead Fitting 3 ea
Does anyone know where they are used? I repurposed two AN837s for the unions used for the fuselage fuel tank vents. My RV-6 uses AN833-4D for the vents and they look nice mounted without the expose wrench flats that the unions have. This would be a nice place to deploy the AN Spacer, 4D.
Also, there are a number of rivet locations that have temporary rivets or unriveted locations around F-718R longeron and F-709 channel. I want to paint the interior soon and wondering when is the right time to pound these rivets.
