I finished SB 18-02-02 and yesterday finally had warm enough temps to allow reinstalling the Stabilator. I followed KAI Page 11-03 instructions for attaching the Stabilator Assembly to the Tail Cone Assembly which details gluing the AN960-416 (OR -416L) washers to the Stabilator Assembly Hinge Brackets. I chose new -416 thin washers and scuffed the surfaces before gluing with super glue.
I had a problem trying to guide the Hinge Brackets over the Pivot Bearings. In my case the bearing inner race would dislodge one of the four washers with each try. The top and bottom U-shaped stiffener plates added to the new hinge brackets severely restrict access for hand placing these washers during reassembly.
My solution was to substitute a larger washer with more surface area for gluing. McMaster-Carr has a 316 Stainless Steel washer 1”OD x 0.281 ID x 0.040 thick. Hole diameter for AN960-416 is 0.265 so this larger washer has hole oversize by 0.016 so you need to center the washer over the hole in the Hinge Bracket when gluing. The new washer clamps the bearing inner race when tightening the assembly so no problem there. You will have to file two flats on the Stainless Steel washers for the outboard Hinge Brackets to clear the T-nut rivets.
A lot of folks have said that installing the Stabilator is a royal pain. With four of these large Stainless Steel washers glued to the Hinge Brackets the Stabilator slide onto the Pivot Bearings like a charm.
My 12 is licensed ELSA so substituting these washers is at my discretion. SLSA will need to follow the SB to the letter.
