Rib #1 on the left wing. The paper is the template which is used to line up the aileron and flap cables on each rib. Without a proper template, it would be difficult to keep the holes straight and prevent binding.
The Pitot/Static tubes are fitted on rib #6 of the left wing. They will be epoxied in place and held tight with safety wire.
Our Escapade will be fitted with a Strobe/Nav light system. With these lights, N370WD will be fully legal to fly at night.
The strobe box is fastened to the outer rib on the left wing. There is only a small area where it will fit on the rib and all the holes will line up.
