Wing Tasks

February 23, 2021 – With the wings on, I started doing various tasks that need to be done while the wings can still come off.

Fuel Tank Attach

After quick verification that the wings were in the correct position from the previous drilling 5 years ago, I drilled the fuel tank attach brackets. This was a simple matter of using a drill bushing to center the hole in the fuselage bracket slot.

When the wings come back off, I’ll install the nutplates for the attach bolts.

Fuel Lines

The next step is the fuel line connections. These are the vent lines and the main fuel feeds from the tanks. The right tank is routed differently because I have a flop tube installed there. The main fuel connection from the left side is a straight shot into the fuselage.

Wing/Fuselage Fairings

There are fairings all the way around the wing root that enclose the gaps you see in the above pictures.

There is a short section underneath where the fuselage skin is attached to the wing skin on each side. I used a hole-finder to start these holes, then enlarged the holes up to the correct size for the screws.

The next part is the large wrap-around panel that wraps around the leading edges of the wings.

These panels have pre-punched holes that match open holes in the wings. Holes do need to be match-drilled to the skins of the fuel tanks.
