Brief Description: Installing Stall Warning System
Final-Drilled #31 the holes in the VA-195E Mount Plate and VA195B Keeper Plate that are used to mount the ES E22-50K Microswitch. Machine countersunk VA-195E for the head of a #40 screw. Final-Drilled #19 the hole in the VA-195E Mount Plate and VA-195 that holds the #8 screw on which the VA-196 Vane pivots. Machine countersunk this hole in the mount plate for the flush head of a #8 screw. Machine countersunk both sets of the nutplate attach holes in the VA-195E Mount Plate. Deburred all holes and edges on the mount plate and the VA-195B Keeper Plate. Radiused the sharp corners on the VA-196 Vane. Primed the parts. Riveted the nutplates onto the VA-195E Mount Plate. Assembled the VA-195E Mount Plate, ES E22-50K Microswitch, VA-195 Vane, and VA-195B Keeper Plate along with the hardware necessary in order to create the Stall Warning Subassembly. Insured that the stall warning vane rotates freely. Placed a dab of Torque Seal in each of the three nuts/screw combination. Made the ground wire by cutting approximately 3 1/2" lenght of #18 wire and attached the terminal fittings according to plans- Figure 1. Attached the Ground Wire to the N.O. (normally open) terminal on the ES E22-50K Microswitch.
