Installing nutplates on seat ribs
|F-916C spacers (Full size)|
Made these from a piece of aluminum bar.
|Priming seat ribs (Full size)|
Deburred, dimpled, cleaned and primed the seat ribs. I primed them now because nutplates need to be installed before assembling them for skin hole drilling. I also fluted the ribs to make them lie flat.
|Inboard rib removable flange riveting (Full size)|
Those pieces of the flange on the inner ribs are riveted to a strap so they can be bolted in place. Riveted them together with the squeezer.
|Flanges bolted back in place (Full size)|
|Riveting nutplates on ribs (Full size)|
Each of the ribs has 3 nutplates. Riveted those into place with the hand squeezer.
