I spent a little more time tonight trying to diagnose the servo issue without any luck. I put that aside and decided to fabricate a clip to keep the upper cowl to firewall hinge pins from sliding out. It’s just a simple piece of 1/16″ angle with one leg cut down and some notches filed in each end.
The hinge pins need a few bends to make them run parallel to the firewall and to provide a handle to use to pop these pins in and out of the retaining clip.
