29-04 step 5

Well I just cannot figure out what I am to do with the pair of an426ad3-4.5 rivet holes for the K1000-4 nutplate on the face of the F1202H canopy ribs.

Step five says to machine countersink the canopy rib _flanges_ and to dimple the _an425ad4_ rivet holes. No mention of what to do with the two an426ad3 rivet holes on the _face_ of the canopy rib.

So I think I should dimple them and machine countersink the corresponding two holes on the F1202M doubler. What did folks do here?

Thanks,
Jeff

1. Machine countersink the AD3-3.5 rivet holes in the rib flanges
2. Dimple the rivet holes in face of the rib that take the AD3-4.5 rivets
3. Dimple all the holes that will take flush screws and AD4 rivets
4. Machine countersink the doublers for the AD4-5 rivets

Er yes. And what about the two AD3-4.5 rivets on the face of the rib? These holes are not for AD3-3.5 or AD4-5 rivets and they are not on the rib flanges and they do not take a flush screw. Do I later machine countersink these locations perhaps?

I dimpled those two holes and countersunk the doubler.
