Section 20-30-00 Painting Maintenance Practices The following procedures should be used to touch-up paint flaking, scratches, nicks, and gouges. Warning: Cleaning solvents and epoxy primer are flammable. Cleaning solvents, epoxy primer, and alodine can cause burns and irritation when skin is contacted. Vapors are harmful and caustic to eyes; Goggles must be worn for eye protection. Cleaning solvents and alodine are poisonous.
Section 20-40-00 Corrosion Control Maintenance Practices 1. Corrosion Control The G500H mounting components are fabricated primarily of aluminum. All components should be inspected regularly for any signs of corrosion. The following procedures should be used for removing corrosion and treating affected areas. 2. Corrosion Removal Remove corrosion by either chemical or mechanical means. a) Paint Removal, Chemical Caution: Do not use chemical paint stripper on composite materials.
(8) Rinse with demineralized water. b) Paint Removal, Mechanical Caution: Do not sand into or expose composite fibers. Do not remove more material than necessary. Do not use aluminum oxide abrasive materials on epoxy/graphite materials. Use abrasive flap wheel, abrasive disk, abrasive paper, or plastic media blast to remove paint. c) Corrosion Removal Note: Aircraft shall be electrically grounded during corrosion removal operations.
b) If damage is through the paint surface prepare area for paint touch-up using following methods. Note: On high strength steel, do not use power tools other than a flap brush or mandrel with abrasive mat; overheating and notching may occur. (1) Remove defect using flap wheel, abrasive disk, abrasive paper, or plastic media blast. (2) Using 320 grit sandpaper, blend edges of paint surrounding repair area to create a smooth transition. (3) Apply aluminum surface treatment if applicable. (Ref. Item 4. Below).
Section 20-50-00 Mechanical Fastener Sealing Methods Seal mechanical fasteners as shown using the following: 1. MTC-20-01-01-310 Use of Sealing Compounds, and 2. MCT 20-05-01 Sealing Figure 20-02.
Section 20-90-00 Dye Penetrant Inspection Methods Warning: solvents can cause burns and irritation when it contacts skin; proper gloves should be worn. Vapors are harmful and caustic to eyes; Goggles must be worn for eye protection. Vapors are harmful to life or health; work should be performed with proper ventilation and / or respirators should be worn while working with Solvents. Solvent cleaners are flammable. Use the following steps to perform dye penetrant inspection: 1.
CHAPTER 31 Section 31-00-00 Instruments 1. Description and Operation The Garmin G500H Flight Display System consists of an instrument panel mounted GDU 620 display and remote mounted LRUs which provide data to the display. The GDU 620 provides controls for the G500H system and a PFD and MFD in the pilot’s primary field of view. The remote mounted LRUs include one GRS 77H AHRS, one GMU 44 Magnetometer, one GDC 74H ADC, and one GTP 59 OAT probe. The G500H system depends on electrical power to function.

Unscrew the three screws that hold the GMU 44 to its mounting rack. 3. Carefully lift the GMU 44 from the rack. 4. Disconnect the wiring harness. ii Installation 1. Visually inspect the connectors to ensure there are no bent or damaged pins. Repair any damage. 2. Connect the wiring harness to the GMU 44. 3.
4. Carefully remove the unit from its mounting location. ii Installation 1. Position the unit and fasten using the four (4) screws. 2. Connect the pitot/static plumbing. 3. Inspect the connector and pins for damage. Repair any damage. 4. Connect the connector to the unit, ensuring that each jackscrew is secured. Original GDC 74H is Reinstalled If the original GDC 74H is re-installed, then no software loading is required.
3. Visually inspect the connectors to ensure there are no bent or damaged pins. Repair any damage. 4. Connect the connector to the GRS 77H, ensuring that each slidelock is secured on both sides. Original GRS 77H is Reinstalled If the original GRS 77H is reinstalled, then no software loading is required. This does not include units that were returned for repair as their software and configuration files are deleted during the repair testing process.
4. Install the six mounting screws into the bezel of the GDU 620. NOTE: The installation configuration settings are stored in the configuration module and will be retained when the GDU 620 is replaced with a new unit. User settings, such as map orientation preferences, are stored internally and will be lost when the GDU 620 is replaced with a new unit. Original GDU 620 is Reinstalled If the original GDU 620 is reinstalled, then no software loading is required.
