Seats, cowling, fuel site tube

 We replaced the lower cushion foam on the seats with memory foam to make them more comfortable (the factory seats are a common complaint among builders).  3 layers of foam were cut to shape, glued together, and then stuffed into the existing fabric seat covers.  This foam does weigh more than the original foam, but figured that the extra comfort was worth the weight penalty.

Some epoxy with flock was added around the fuel door to close up a gap near the hinge and make it look a bit nicer.

Quite a bit of sanding and filling work (using 3M lightweight filler) was done on all three cowl pieces to shape and smooth them out.  Some lightweight filler was also added around the NACA duct to smooth the transition areas.

A protective guard around the fuel site tube was completed, painted black, and installed.  The site tube has a striped pattern behind it to help visualize the fuel level.  Refraction causes the pattern to change when fuel is in the tube.  We also have an electronic fuel bingo sensor that indicates when fuel is low.  This was tested and verified to be working, but we will do some testing before setting the level at which it triggers.

We also started some work on the right (passenger) door.  The lexan sheets that form the doors were trimmed to fit better against the fuselage.  We still need to do the same for the pilot side door.  Hours: 21
