This evening I walked through Chapters 26 and 27 to confirm the work that was accomplished at the QB factory. Everything was done with the exception of a few small items like installing Snap Bushings and the installation of the Cabin Heat Selector Boxes...
One note on the Cabin heat boxes. After bolting them on, you have to seal them against the firewall with Proseal. This is done on the inside of the fuselage.
Before you do this, make sure you tape the areas you don't want proseal. This includes the round tube that protudes through the firewall and the firewall itself. Take the time to mask them.
I didn't and mine turned into a mess. From now on, masking tape will always be used with proseal application.....
