Short work session but it has been a task I have been postponing for a long time because I couldn't find out a way to drill new holes through the seat ribs using a step drill.
I didn't have any drilling device which would fit between the ribs. It's really narrow in there. The step drills don't fit in my angle drill so that also was no option.
Fortunatly I found a small air drill from a friend that had a similar hex adapter where the back of my needle step drill fitted in.
I drilled the two holes so that I can run the Pitot line and AOA line from the outerbay through 2 ribs to the conduit which runs to behind the baggage area where I have free routing access to the ADAHARS module.
Inserted the nylon tubing through the new holes.
