Window, fairings, latch, antenna, etc

The left triangle-shaped window was installed.  A very thin gasketing was applied to the inside before screwing on the window to help seal it.

Two fiberglass fairings were installed.  These were previously painted white, and these fairings clean up the area between the windshield and wing root.  A large hole was also drilled in the top of the pieces to accommodate the wing's clevis pin (This pin is removed to fold the wings back).

The sensor for our bingo fuel indicator was glued to the header tank in a position that is about 1/3 down from the top.  This is our best guess for position and we may move it up or down later based on later testing.  We don't want it placed too near the top or else we can get false triggers if a wing tank becomes unported during descents and/or turns, but we don't want it too low as we want to have ample time to respond to a low-fuel condition.

We are going to remake the rear baggage walls as the ones previously made don't fit well (holes no longer line up after fabric shrinking), and we want to make the sides a little bit longer.  Some planning was done for this, and we're now waiting for some parts to arrive before fabricating this.

We had an issue when installing the door latch for the left door.  The position of the door latch was 180 degrees off when drilled, and it couldn't be rotated 180 degrees because the drilled hole was slightly off-center.  So to fix this part, the holes in the two parts were filled using a TIG welding machine, and then redrilled with the latch in the correct position.  These parts will be painted black before installation.

Two inspection plates were previously painted, but had tons of dust in the paint coat, so these were polished up to get rid of the blemishes.

We are adding an inspection hole and plate in the bottom floor of our baggage compartment.  This allows for easy inspection of the lower antenna (for ADSB), and the battery vent ports.  We had previously thought that we could just remove the floor to inspect these, but found that it is impossible to do this without also removing some flap pulleys in the fuselage.  So adding this inspection port will make inspections much easier in the future.

The com antenna (with its base now painted) was installed in the (newly painted) turtledeck.  Hours:

A few cover plates are in the process of being made.  Each plates will close off part of the opening for each pulley in the wings.  Hours: 25
