Notification 15-09-15: This is the mechanical push button Spar Pin Switch upgrade. Removed the “old” spar pin switch from the F-1248 Arm Rests. Match-drilled #19 holes (2 on each side) on the flanges of the arm rests. Also drilled a #30 hole through the F-1248B Spar Pin Switch Plate and the Arm Rest on each side. Riveted the #30 holes. Deburred the F-00104 Spar Pin switch Plates and primed and painted them. Also primed the camloc stud for the mapbox and then painted it black. Placed six SB625-8 Snap Bushings in the holes in the F-1206A, F1204D and F-1204A Bulkheads where the stabilator cables pass.
