installation of SB-0001 (Service Bulleting 0001) regarding the Vertical Stabilizer Bottom Hinge bracket. Drilled out the rivets. Final drilled TO WRONG size the bolt holes. Instead of #8 screw i drilled #10. Asked VANS and VANS replied on March 12 2001 indicating: ...Just heard back from engineering on this and they have approved the larger hardware #10 being used in place of the #8 screws. This will most likely require you to modify a washer in order to keep from having interference with the bend radius on VS-01010-1 Hinge Bracket but it is also acceptable." Following that i ordered NAS1149F0364P (AN960-10) MS21042-3 and AN509-10R11. Installed the hardware. It is not necessary to modify the washer as there is no interference with the radius on the bracket. Torqued the screws at 42lbs/inch (28+14 friction). Marked all nuts with RED marker.
