BEECHCRAFT DUKE 60 SERIES MAINTENANCE MANUAL
Beechcraft 60 Duke · Avionics Manual
Overview
This document is a maintenance manual for the Beechcraft Duke 60 Series, detailing the communications systems and static discharging practices. It is intended for maintenance personnel and pilots who need to understand the operation and maintenance of static wicks used to dissipate electrical charges that can interfere with avionics. The manual provides specific procedures for the removal and installation of static wicks, including differences in practices based on the aircraft's serial number. It emphasizes the importance of maintaining proper static discharge to ensure safe operation and prevent equipment interference.
- Static wicks are crucial for dissipating electrical charges during flight.
- Prior to serial P-581, two static wicks are installed on each wing tip, elevator, and rudder; three are used for serial P-581 and later.
- Installation torque for static wicks (P-581 and after) is 4.7 inch-pounds.
- Static wicks must be maintained to prevent interference with avionics systems.
- Proper cleaning and preparation of surfaces is essential for static wick installation.

Static Discharging - Description and Operation
This section explains that static electrical charges can accumulate on the aircraft during flight, potentially causing interference with radio and avionics systems. To mitigate this, static wicks are installed on the aircraft's flight surfaces. Prior to serial number P-581, two static wicks were installed on each wing tip, elevator, and rudder. For serial P-581 and later, three static wicks are used on each of these surfaces.
Static Discharging - Maintenance Practices
This section outlines the maintenance practices for static wicks. For aircraft prior to serial P-581, static wicks are bolted on, while for later models, they are screwed into bases riveted to the surfaces. Detailed procedures for removing and installing static wicks are provided, including cleaning and preparation of the surfaces, and specific torque values for installation.
Safety notes
- Static electrical charges can cause interference with avionics and pose a danger to personnel.
- Dissimilar materials must be protected against electrolytic corrosion during assembly.

This electrical charge, if retained, can cause interference in radio and avionics equipment operation. It is also dangerous to personnel disembarking after landing and to personnel servicing the a irplane . Therefore, static wicks are installed on the trailing edges of the flight surfaces and wing tips to aid in the dissipation of the electrical charge. Prior to serial P-581 two static wicks Iare installed on each wing tip, two on each elevator, and two on the rudder. At serial P-581 and after three static wicks are installed on each wing tip, three on each elevator, and three on the rudder. "END" A15 23-60-00 Page 1 Jun 13184 BEECHCRAFT DUKE 60 SERIES MAINTENANCE MANUAL STATIC DISCHARGING - MAINTENANCE PRACTICES Prior to serial P-581 static wicks, two on each wing tip, two on each elevator, and two on the rudder, are bolted to the flight surfaces. Each of these ten static wicks are removed and installed in the same manner. Starting at serial P-581 and after, there are three static wicks on each wing tip, each elevator. and the rudder. These fifteen static wicks are screwed into their bases which are riveted to the flight surfaces. These bases should not need to be removed in normal service. I STATIC WICK REMOVAL (Prior to P-581) a. Remove the two screws and lock washers securing the wick to the surface. b. Remove the wick from the surface. I STATIC WICK INSTALLATION (Prior to P-581) Clean around the static wick area by: a. Remov ing all anodic film, grease, oi l, paints, lacquer, metal finishes or other high resistance properties with Minnesota 3M No. 600 grit sandpaper, or equivalent, and solvent (41 , Chart 201 , 91-00-00). The mating surfaces must be smooth and contoured so that maximum surface area is in actual contact. A15 NOTE Acceptable substitutes for the preceding may be used in accordance with MIL -8-50878 or the surface may be prepared in accordance with MIL-M-3171 C. NOTE Dissimilar materials are not to be used in i ntimate contact unless suitably protected against electrolylic corrosion. Whenever it is necessary that any combination of such metals be assembled, an interposing material compatible to each should be used. b. Install the wick, using the two screws and lock washers. c. Refinish the surface area around the wick attachment point with the original finish or a clear laquer conforming to MIL-L-6806. STATIC WICK REMOVAL (P-581 and after) a. Unscrew the static wick from the base. b. Remove the static wick and lock washer. STATIC WICK INSTALLATION (P-581 and after) The threads must be clean and free of grease, oil and paint. a. Install the static wick and lock washer. b. Torque the static wick to 4.7 inch-pounds. 23-6()-()() Page 201 Jun 13/ 84 IDETAIL A 23-60-00 Page202 Jun 13/84 DET A IL A BEECHCRAFT DUKE 60 SERIES MAINTENANCE MANUAL NOTE The static wick installation shown is for airplanes prior to P- 58 1 with static wicks installed in groups of two (ten per airpl an e) .
