Lots of nutplates to rivet. All straightforward, but needed to be careful to select and confirm the correct type!
My technique for this type of nutplate attachment is to cleco them on, and prior to squeezing the rivets screw in the relevant screw to ensure proper alignment. This also acts as a check that the nutplate threads are fit for purpose and will accept the screw.
I find that Boelube on the screw thread helps.
