CH-640 Fuselage Hull - Stage One (36 of 206)




Install the two horizontal panels (640-F-14-1) to the firewall.  NOTE:  the panels are 90 deg. to the firewall.  I could not find anything in the drawings that said what rivet pitch to use.  However the image from Zenair did show 6 rivets so I drilled A5 P20 which worked out nicely.
