Fuel lines, Painting, Window, Door

Finished up some priming and painting (vestal white) on several parts, including the aluminum turtledeck, two butt-rib fairings, two wing cuff fairings, and the comm. antenna base.  This completes all the painting, minus a few inspection plates that will be done later.


The right side Lexan window was installed (riveted in place).  The left side wasn't installed yet because we were still using the opening for easy access to the fuel lines on that side.

Fuel lines were run from the left wing to the header tank which included a cutoff valve.  This valve will normally be left open, but can be closed when the plane is parked on a slope to prevent fuel from cross-flowing from one wing into the other.  We determined that it is nearly impossible to reach this valve when seated and buckled in as it is directly behind the pilot.  So as a safety feature, we added a control cable for push/pull control of the valve.  This allows the valve to be opened if it is inadvertently left closed prior to takeoff.

The pilot side door was installed.  We found a tiny crack in the Lexan near one of the rivets after installing the door.  A tiny hole was drilled in the Lexan at the end of the crack to prevent it from spreading.  Hours: 30
