Pg. 12-10 Step 1: Tapped a sacrificial nutplate 6-32 to accept #6 screw without resistance and used it as my drilling guide. Threaded the #6 screw through the #27 hole in the Tail Cone Assy into the nutplate until snug. Assured that the tabs of the nutplate were parallel with the edge of the Tail Cone Assy. Clamped one end of the nutplate. Step 2: Match-Drilled #40 using a 12" extension drill through one of the nutplate rivet holes. Clecoed then drilled the other. Repeated this operation with the remaining 11 nutplate locations. Step 3: Partially tapped 6-32 the two nutplates located below the Stab Hinges. Marked these nutplates with a dab of paint for identification.
