July 2th. Steps 3 to 7 29iS/U-07 we started the canopy rib assemblies, to step 4 we used a guide bar to made the countersink #40 to avoid enlarging the hole, because the part was very thin.
July 3th. We continued on this page, step 8 and 9 were completed, in step 9 it was necessary to change the indicated rivets by shorter ones (AN426AD4-4 to the F-1202M-L and AN470AD3-5 to F-1202Y), because when we tightened the rivets, they ended up with the shape of the shoes.
July 4th. Today we did the step 10 repeating the previous process.
