Figuring out puzzles continued this week. More work was done cleaning and laying out the complex rudder pedal assembly. Robert continued sorting out wires and connectors, some of which lack a clear indication of what they do. Work also continued on things on or near the interior firewall that need to go in before the rudder pedals can be installed. The parking brake was reconnected. Because four trim pulleys need to be mounted against the firewall, we started figuring out the trim system and its cables. We will be installing new cables.
