Brief Description: Static air system, A/P servo harness, some firewal
Today I worked on the static system. The AOA probe does not have a static port so installed a static port on each side of the aft fuselage. The ports are made of 3/16” rivets with the mandrel taken out. I ran a T-fitting to join the sides and bring the line up to the AHARS unit. There is another T-fitting to bring the static line to the instrument panel for the backup gauges and an alternate static port. The alternate port is mounted below the right instrument panel. I used a fuel petcock to function as the alternate static source that vents to the cabin when open. I noticed elevator trim cable was running over the right rudder cable. I rerouted this to prevent chafing. I decided to install the wire harness for the future auto pilot servos. I removed the backup slip indicator. I decided this would only become necessary should the EFIS or AHARS fail. In that scenario, the coordination is easy to control on the Sonex by feel. I installed a circuit breaker for the servos and extended the DC bus bar to accommodate this. I plan on putting the autopilot CWS switch just above the throttle quadrant on the panel where it can be activated by the throttle hand easily. I also installed the new fuel cap from Peter Anson in Australia. I replaced the hardened fuel vent line.
