Fit hinge to elevator per plans. Drill bottom mini-rib holes while ensuring trailing edge alignment per plans.Dissasemble trim tab and dimple bottom skin holes and bottom mini-rib holes. Squeeze 426-3 rivets attaching top skin to mini-ribs. Used MK-319-BS blind rivet in last hole.Reassemble trim tab with clecos and check alignment again.Squeeze hinge to trim tab and elevator.Attach bottom of trim tab skin to mini-ribs with MK-319-BS blind rivets while ensuring alignment.
