Therefore, it is the installer's responsibility to make the final determination of applicability for each individual airplane. Prior to completing the installation, and before returning the airplane to service, the installer must complete and submit a completed Form FAA 337 - Major Repair & Alteration (Airframe, Powerplant, Propeller, or Appliance) to the appropriate FAA Aircraft Registration Branch. The form must include the following: • Description of the autopilot servo installation. • Description of how the autopilot servos interface with existing equipment and systems. • Appropriately approved or acceptable data that demonstrates compliance. Refer to AC 43.9-1G - Instructions for Completion of FAA Form 337 for additional information. 4.1 Pre-installation Information Read and understand the following before proceeding with installation activities. Always install avionics equipment in accordance with the instructions in this manual and the guidance and approved engineering methods outlined the following FAA documents: • AC 23.1311-1C - Installation of Electronic Display in Part 23 Airplanes • AC 43.13-1B - Acceptable Methods, Techniques, and Practices - Aircraft Inspection • AC 43.13-2B - Acceptable Methods, Techniques, and Practices - Aircraft Alterations The technician who will authorize the airplane's return to service should agree with the installation plan (i.e., methods, component locations, wiring harness routing, etc.) before installation activities begin. This will help avoid potential rework should any part of the installation be found non-compliant.

SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 Page | 5-1 5 Control Cable Verification The SkyView Autopilot system for the Beechcraft Bonanza Model 36 series of airplanes is designed to attach to the airplane's original control cables. It is important for installers to verify the condition, rigging, tension, and diameter of the control cables before starting installation activities. The diameter of control cables should be measured in the vicinities where the autopilot servos will be installed. DO NOT connect an autopilot system to improperly rigged and tensioned control cables. This includes control cables that are frayed or do not meet manufacturers' specifications. To inspect the aileron control cable, installers need to access the area under left rear seat near FS118.5 (see Figure 1 for exact location) in accordance with the manufacturer's service manual. To inspect the elevator and rudder control cables, installers need to access the area behind the baggage area near FS207 (see Figure 17 for exact location) in accordance with the manufacturer's service manual. Dynon's bridle cable clamps are designed to meet the requirements below for wire rope as specified by MIL-DTL-83420.

SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 Page | 7-1 7 Initial Servo and Bracketry Installation This section provides instructions for installing the roll, pitch, and yaw servos and bracketry, and then attaching bridle cable assemblies to the aileron, elevator, and rudder control cables. The instructions apply to all Bonanza Model 36 airplanes. These instructions assume that the areas affected by these installations are unmodified from the factory-delivered configuration. Yaw servo installation in not supported in Bonanza 36 models, serial numbers E-1 through E-571. Printing the figures at the end of this document and keeping them on-hand during installation activities is recommended. 7.1 Additional Tools The following non-typical tools are needed to complete the installation: • Nutplate Drill Jig for K1000-3/MS21047-L3 nutplates, • Swage compression tool appropriate for ST2-2 stop swages, • Cutters for 1/16" diameter wire rope. 7.2 Roll Servo Installation The roll servo and bracketry are installed in the fuselage on the forward, left-hand side of the Rear Spar Carry Through near FS118.5 (see Figure 1 for exact location). To install the roll servo, installers need to access this area in accordance with the manufacturer's service manual. See Figure 11 for an example of a complete installation. Remove any previously installed autopilot equipment that may interfere with the new servo installation. Make sure all flight control cables are rigged and tensioned in accordance with manufacturer’s instructions. Always disconnect aircraft battery before starting installation activities. Always deburr drilled holes. Unless otherwise specified, torque all fasteners per specifications in AC 43.13-1B, Table 7-1. Include specified friction drag value when torquing screws. Page | 7-2 SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 To install the roll servo: 1. Remove capstan and cable guard from roll servo (see Section 11.5 for instructions). DO NOT loosen or remove the shear screw from the servo disc! 2. Temporarily attach roll servo to plate bracket, as shown in Figure 3. Finger-tighten castle nut, and tighten, but do not torque hardware. Cotter pin and washers not needed yet. Position servo capstan so orientation mark on capstan faces away from servo and is fully seated on servo disc. The capstan has a hole that fits over shear screw head. 3. Temporarily attach forward support bracket and rear spar bracket to plate bracket, as shown in Figure 4. Tighten, but do not torque hardware. 4. Place plate bracket into airplane, as shown in Figure 5 and Figure 6. Make sure aileron control cable is on top of assembly and to rear of servo capstan. Positioning of servo capstan in relation to aileron control cable in height and distance is critical for an airworthy installation. 5. Position rear spar bracket on forward face of Rear Spar Carry Through so flanges on bracket span lightening hole (see Figure 5), and then clamp in place. 6. Loosen bolts securing forward support bracket and rear spar bracket to plate bracket (with roll servo). 7. Using slots in plate bracket, adjust and position assembly so aileron control cable is 1/4" aft of cable guard and tracks (inboard and outboard) down center of capstan (see Figure 6), and then secure in place. Tighten, but do not torque hardware. 8. On outboard side of lightening hole, use pilot holes on rear spar bracket as guides to match drill up to #30 holes through front side of spar web only (see Figure 7), and then temporarily fasten in place. 9. Use pilot holes on forward support bracket as guides to match drill up to #18 holes through bracket and floorboard stringer, as shown in Figure 7. 10. Remove forward support bracket and plate bracket. 11. Use pilot holes on rear spar bracket as guides to match drill up to #20 holes through bracket and front side of spar web only (see Figure 8). 12. Permanently rivet rear spar bracket to spar web, as shown in Figure 9. 13. Permanently fasten support bracket to floorboard stringer, as shown in Figure 10. 14. Remove capstan from roll servo. 15. Permanently fasten roll server to plate bracket, and then safety wire roll servo bolts (see Figure 11 for example). SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 Page | 7-3 16. Permanently fasten plate bracket assembly to forward support bracket and rear spar bracket, as shown in Figure 12. To attach the roll servo to the aileron control cable: 1. Secure ailerons in center of travel. 2. Insert bridle cable's engagement swage into capstan's engagement hole. 3. Start from swage engagement hole and wrap bridle cable 1/2 time in each direction around capstan, as shown in Figure 13. Securing (e.g., taping) the bridle cable to capstan grooves prevents cable from unraveling when handling. 4. Temporarily attach capstan to roll servo (see Figure 13). Finger-tighten castle nut. Cotter pin not needed yet. Position servo capstan so orientation mark on capstan faces away from servo and is fully seated on servo disc. The capstan has a hole that fits over shear screw head. 5. Determine where inboard bridle cable clamps should attach to aileron control cable: A. If bridle cable clamps fit on outboard side of the turnbuckle (see Figure 14), use the 5/32" clamps. B. If bridle cable clamps fit on inboard side of the turnbuckle (see Figure 15), use the 1/8" clamps. 6. Make sure aileron control cable where bridle cable clamps will attach is clean and free of dirt and grease. Roll servo installation kit contains bridle cable clamps for 5/32" and 1/8" diameter control cables, ensure correct clamps are used per determination in Step 5. 7. Use bridle cable clamps to loosely connect inboard and outboard bridle cable ends to control cable, as shown in Figure 14 or Figure 15. 8. Position bridle cable clamps so that: • Capstan is positioned as shown in Figure 14 or Figure 15. • Clamps are located as shown in Figure 14 or Figure 15. • Clamps are positioned to avoid contacting any structure. 9. Mark locations for swage stops on bridle cable at outside edges of bridle cable clamps. 10. Remove bridle cable clamps from bridle cable, and then remove capstan from roll servo. 11. Slide a swage stop onto one end of bridle cable so it is aligned with mark on bridle cable. 12. Permanently attach swage stop to bridle cable, and then trim bridle cable end flush with outside edge of swage stop. Page | 7-4 SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 13. Repeat Steps 11 and 12 on the other end of bridle cable. 14. Temporarily attach capstan to roll servo, as shown in Figure 13. Finger-tighten castle nut. Cotter pin not needed yet. Position servo capstan so orientation mark on capstan faces away from servo and is fully seated on servo disc. The capstan has a hole that fits over shear screw head. 15. Rotate capstan to locate swage engagement hole on opposite side of capstan from aileron control cable. Make sure bridle cable ends extend from capstan, as shown in Figure 14 or Figure 15. 16. Use bridle cable clamps to loosely connect bridle cable ends to aileron control cable, as shown in Figure 14 or Figure 15. Make sure clamps contact swage stops at each end of bridle cable. 17. Make sure bridle cable does not contact cable guard. The bridle cable will prematurely wear if it contacts the cable guard throughout its travel. 18. If cable guard interferes with bridle cable, adjust cable guard position (see Section 11.6: Cable Guard Adjustment), and then repeat Step 17. 19. Tension and temporarily secure bridle cable to 15–20 lbs. Make sure swage engagement hole is on opposite side of capstan from aileron control cable. The tension on the bridle cable should never exceed the manufacturer's specified tension for the control cable. 20. When satisfied with tension and capstan position, tighten all bridle cable clamp nuts to 35-40 in-lb. 21. Use a feeler gauge to measure gaps between bridle cable clamp halves (top and bottom). Make sure gaps meet the following criteria: • Gap measurements on both sides of clamp are not less than 0.003" and not more than 0.050". If clamp gap measurements do not meet criteria above, measure diameter of control cable, and then contact Dynon Technical Support for a resolution. Out-of-specification cable clamps can slip under load. 22. Permanently attach capstan to roll servo (see Section 11.5 for instructions).

SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 Page | 8-1 8 Servo Electrical Connection Refer to the following documents at dynoncertified.com/docs for complete electrical connection instructions: • SkyView HDX System Installation Manual • SkyView HDX Wiring Diagram - Twin Engine Dynon provides the SV-NET-SERVO Network Autopilot Servo Cable Kit to aid in wiring the servos. Contact Dynon Sales for more information. Servo electrical harnesses must be routed through the airframe structure as outlined in AC 43.13-1B, Chapter 11, Section 3. Servo electrical harnesses must not chafe against airframe structure. after all electrical connection activities are complete, visually inspect all harness routing. Servo electrical harnesses cannot interfere with the airplane's flight controls. After all electrical connection activities are complete, confirm this by moving all controls through full range of motion per manufacturer's maintenance instructions. Terminate servo electrical harnesses with a D9 connector shell with female pins; terminate pigtails on servo electrical harnesses with mating D9 connectors. Power for all servos must be controlled by a switch prominently mounted on the instrument panel labeled AP Power. This provides the pilot the ability to quickly turn off power to the servos should it be needed. Servo power (AP Power) and the pitch and roll servo disconnect (AP DISC) circuits are required to be separate from the power and signal circuits provided over the SkyView Network. The servos should receive power from a common power source with circuit protection sized for the loads associated with all servos. Do not connect the yaw servo disconnect circuit to the pitch and roll servo disconnect (AP DISC) circuit. This will result in a yaw servo calibration test failure. The yaw servo disconnect circuit should only be connected to a Yaw Damper button or left unconnected if no Yaw Damper button is installed. After electrically connecting the Autopilot servos, perform the Servo Calibration Procedure (see Section 11.2: Calibration Procedure for instructions).

SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 Page | 11-1 11 Servo Maintenance This section provides maintenance information for autopilot servos and associated bracketry. See the 103221-000 SkyView HDX General Maintenance Manual for information about troubleshooting the Autopilot system interface. No special tools or facility are required to service autopilot servos and associated bracketry. 11.1 Service Every 12 months (1 calendar year), the autopilot servo components and wiring harnesses should be inspected to ensure continued integrity of the installation (see below). • Inspect for security of servo attachment, which includes visual inspection of brackets and other supporting structures that attach to the airplane. • Inspect for signs of corrosion. • Inspect condition of wiring, shield terminations, routing, and attachment/clamping, along with any airplane penetration points. In the event of system failures, contact Dynon technical support. Always have a properly rated mechanic or qualified facility remove a failed component. 11.2 Calibration Procedure The SkyView HDX Autopilot servo settings are available for download as a configuration file that is loaded into the SkyView HDX display. This file configures the autopilot servo performance settings to meet the applicable certification regulations. Servo calibration cannot be performed without the following: • An ADAHRS module (SV-ADAHRS-200) installed and configured in the SkyView network. • All servos installed and configured in the SkyView network. • V-speeds correctly entered in SkyView HDX. (See the SkyView HDX System Installation Manual document for instructions.) To make a new servo appear on the SkyView HDX display, configure the SkyView network (SYSTEM SETUP > NETWORK SETUP > CONFIGURE). (See the SkyView HDX System Installation Manual document for instructions.) To calibrate the servos, enter the Servo Calibration Wizard (SETUP MENU > HARDWARE CALIBRATION > AP SERVO CALIBRATION > CALIBRATION) and follow the onscreen instructions to calibrate the servo(s). SkyView HDX checks the status of the AP Disengage Button. If SkyView HDX detects that the button is pressed (the input is grounded) upon entering AP SERVO CALIBRATION, the AP Page | 11-2 SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 Disengage Button is assumed to be stuck (or incorrectly installed), resulting in the following message being displayed, and the Autopilot servo calibration is aborted: "The servo disconnect switch appears to be pressed and may be installed incorrectly. The servo disconnect switch should be a type Momentary, Push Button Normal Open (PBNO). Press cancel below to return to the servo calibration menu." If the servo calibration procedure is not successful, inspect the button and servo wiring. (See the 103261-000 SkyView HDX System Installation Manual document for instructions.) If button type and wiring is correct, call Dynon Technical Support. If the servo calibration procedure is successful, SkyView HDX will automatically instruct you to run the servo test procedure. (See Section 11.3 for instructions.) 11.3 Test Procedure The servo test procedure requires a successful servo calibration. The servo test procedure verifies that each servo is configured properly by moving the control surfaces while the installer verifies the correct movement. You may run this procedure on its own at any time after a successful servo calibration. SkyView HDX will not display AP status on the Top Bar until after this test procedure is successfully completed. To run this procedure on its own (after a successful servo calibration procedure), enter the Servo Test Wizard (SETUP MENU > HARDWARE CALIBRATION > AP SERVO CALIBRATION > TEST) and follow the onscreen instructions to test the servo(s). 11.4 Servo Operation Check Complete the following procedures to confirm the autopilot servos are operating correctly. To check the pitch and roll axes: 1. Make sure master power and Autopilot servo power are ON. 2. Center, and lightly hold in place, flight control yoke. 3. Align HDG/TRK bug with current heading. 4.

Servo installation procedures often require the temporary removal and re-attachment of capstans. Unless otherwise specified, torque all fasteners per specifications in AC 43.13-1B, Table 7-1. Include specified friction drag value when torquing screws. Reference Figure 46: Exploded View of a Typical Servo Capstan Assembly when performing the following procedure. To remove and re-attach the capstan: 1. Remove cotter pin that secures castle nut to servo shaft. 2. Mark position of castle nut in relation to servo shaft, and then remove castle nut from servo shaft. 3. Remove wave washer from servo shaft. 4. Removed nylon washer from servo shaft. 5. Remove capstan from servo shaft. The shear screw does not need to be removed from the servo disc. The capstan has a hole that fits over the shear screw head. If the shear screw is loosened, it must be completely removed and replaced (see Section 11.7: Shear Screw Replacement). 6. Place capstan onto output shaft, aligning hole in capstan with shear screw head located in servo disc. 7. Replace nylon washer on servo shaft. 8. Replace wave washer on servo shaft. 9. Finger-tighten castle nut onto servo shaft, and then use a wrench to tighten until slot in castle nut lines up with hole for cotter pin in servo shaft. DO NOT overtighten the castle nut! Tightening the castle nut beyond 4 in-lbs may prevent the capstan from rotating freely in the event of shear screw failure. 10. Install new cotter pin to secure castle nut to servo shaft. SkyView HDX - Autopilot Servo Installation & Maintenance Manual, Beechcraft Series 36, Rev F, 4/14/2023 Page | 11-5 11.6 Cable Guard Adjustment Dynon's autopilot servos are shipped with cable guards installed. The cable guard may need to be repositioned to avoid interference with the flight control cables or the bridle cables during servo installation procedures. The following procedure details the task of adjusting a cable guard. Unless otherwise specified, torque all fasteners per specifications in AC 43.13-1B, Table 7-1. Include specified friction drag value when torquing screws. Reference Figure 46: Exploded View of a Typical Servo Capstan Assembly when performing the following procedure. To adjust the cable guard: 1. Remove capstan from servo shaft (see Section 11.5 for instructions). 2. Remove screws and washers that secure capstan guard to servo. 3. Rotate capstan guard to correct position. 4. Secure capstan guard to servo with screws and washers. 5. Re-attach capstan to servo shaft (see Section 11.5 for instructions). 11.7 Shear Screw Replacement Dynon autopilot servos come equipped with a capstan. The capstan connects to the servo via a frangible shear screw. The shear screw can be broken by the pilot to restore system movement should a servo become jammed. It is possible for turbulence loads acting on the airplane to cause a shear screw to fail, even though the servo never jammed. In the event of a shear screw failure, contact Dynon Technical Support to request a 102991-000 Shear Screw Replacement Kit. Shear screw replacement instructions are provided in the Dynon Servo Shear Screw Replacement Instructions document included in the Shear Screw Replacement Kit.

The roll servo and bracketry are installed in the fuselage on the forward, left-hand side of the Rear Spar Carry Through near FS118.5 (see Figure 1 for exact location). To install the roll servo, installers need to access this area in accordance with the manufacturer's service manual. See Figure 11 for an example of a complete installation. Make sure all flight control cables are rigged and tensioned in accordance with manufacturer’s instructions. Always disconnect aircraft battery before starting removal and installation activities. Unless otherwise specified, torque all fasteners per specifications in AC 43.13-1B, Table 7-1. Include specified friction drag value when torquing screws. To remove the roll servo: 1. Disconnect D9 cable harness connector from servo. 2. Mark locations of bridle cable clamps on aileron control cable. Securing (e.g., taping) the bridle cable to capstan grooves prevents cable from unraveling when handling. 3. Loosen bridle cable clamps. 4. Unfasten hardware that secures roll servo bracket assembly to forward support bracket and rear spar bracket (see Figure 12). Retain hardware for installation. 5. Remove capstan (with bridle cable) and cable guard from roll servo (see Section 11.5 for instructions). DO NOT loosen or remove the shear screw from the servo disc! 6. Remove safety wiring from roll servo bolts. 7. Unfasten hardware that secures roll servo to plate bracket (see Figure 3). Retain hardware for installation. 8. Remove roll servo from plate bracket.

Finger-tighten castle nut, and tighten, but do not torque, other hardware. Cotter pin and washers not needed yet. Position servo capstan so orientation mark on capstan faces away from servo and is fully seated on servo disc. The capstan has a hole that fits over shear screw head. 5. Place roll servo bracket assembly into aircraft, as shown in Figure 5 and Figure 6. Make sure aileron control cable is on top of assembly and to rear of servo capstan. Positioning of servo capstan in relation to aileron control cable in height and distance is critical for an airworthy installation. 6. Secure roll servo bracket assembly to forward support bracket and rear spar bracket, as shown in Figure 12. 7. Rotate capstan to locate swage engagement hole on opposite side of capstan from aileron control cable. Make sure bridle cable ends extend from capstan, as shown in Figure 14 or Figure 15. 8. Make sure aileron control cable in area where bridle cable clamps will attach is clean and free of dirt and grease. 9. Use bridle cable clamps to loosely connect bridle cable ends to aileron control cable at marks made during removal process. Make sure clamps contact swage stops at each end of bridle cable, as shown in Figure 14 or Figure 15. 10. Make sure bridle cable does not contact cable guard. The bridle cable will prematurely wear if it contacts the cable guard throughout its travel. 11. If cable guard interferes with bridle cable, adjust cable guard position (see Section 11.6 for instructions), and then repeat Step 10. 12. Tension and temporarily secure bridle cable to 15–20 lbs. Make sure swage engagement hole is on opposite side of capstan from aileron control cable. The tension on the bridle cable should never exceed the tension on control cable. 13. When satisfied with tension and capstan position, tighten all bridle cable clamp nuts to 35-40 in-lb.
