Training Done and Back at It!

Time: 1 Hour

Flew back to Chicago today after finishing up my 6 month training. I’m happy to say I passed once again. This was my 18th time down in Tucson for my Flight Safety training. It’s always fun but challenging.

After taking care of some housework I got out to the hangar for a little bit. First order of business on all the ribs is create some holes for future wiring and piping. You have to do some planning for your future plans. Here are my goals for each wing:

Left Wing:
– LED Landing Light – Left Wing-Tip
– LED NAV Light – Left Wing-Tip
– LED Strobe – Left Wing-Tip
– Pitot Tubing – Left Lower Wing
– AOA Tubing – Left Lower Wing
– Pitot Heat Wiring – Left Lower Wing

Right Wing
– LED Landing Light – Right Wing-Tip
– LED NAV Light – Right Wing-Tip
– LED Strobe – Right Wing-Tip
– Auto-Pilot Servo Wiring – Right Lower Wing

In each wing I will place a 3/4″ CPVC pipe that will run from the outboard most rib to the inboard most rib. This will allow for wiring runs from inside the fuselage out to the wing tip for lighting. It will also have a cut out between a couple of ribs to allow for the pitot heat wiring and the auto-pilot servo wiring. In the leading portion of the aft ribs there are a few holes that are already drilled from the factory. One is a 7/16″ hole made for the pitot tubing. The others are holes left from the machining process. The plan is to drill the machining holes to 3/8″. This will give me two 3/8″ holes and one 7/16″ hole for all the ribs except the last 3 outboard ribs. In each hole I will put a snap bushing that will leave a 1/4″ ID hole. This will give me two places for the pitot tubing and AOA tubing. The third hole will be for extra or future runs, this is easy to do now. So I made a template out of sheet aluminum to mark all the ribs for the 3/4″ pipe. This hole will be 7/8″ OD when done.

With this template I drill a small hole that I could slip a sharpie through and mark the rib for drilling.

So I chucked up the UniBit in the drill press and hit all the left wing ribs.

Tomorrow I will get a good days work done in the hangar and drill the right wing ribs. Then the fun deburring work begins!
