I am working on RV 9 horizontal stabilizer and the plans said to not rivet the skin to the inner ribs in 10 locations for the fairing attach. But nowhere is there a mention if these should be dimpled or not. I went ahead and matched drilled the skin to the inboard ribs.
The plans say to add 632 nut plates on sheet 44.
But do I dimple these 10 holes or leave them undimpled? I am inclined to leave them undimpled since it seems easy enough to dimple after the horizontal stab is together. Does the fairing need these holes dimpled in order to have room for the fairing attach countersink screws?
Thanks
