Table 4-10 Gea 24 Weight And Size; Figure 4-43 Example Support Structure - Garmin GI 275 Installation Manual

If installing the GEA 24 on the avionics shelf or the instrument panel, ensure the new fastener holes
maintain a minimum of 2D edge distance and 3D spacing from existing holes. Additionally, ensure the
combined weight of the GEA 24 and existing equipment remain within the established weight limit of the
shelf or instrument panel.
If an avionics shelf or suitable platform for the GEA 24 is not available, a support structure can be
fabricated. The support structure must:
• Be electrically bonded to the airframe per Section 4.3
• Be made from 2024-T3 aluminum per AMS-QQ-A-250/5, minimum 0.040 inches thick
• Be protected from corrosion by applying conversion coating per MIL-DTL-5541 Type II or
MIL-DTL-81706 Type II and primed with epoxy primer per MIL-PRF-23377, Class N
• Be fabricated in accordance with methods outlined in AC 43.13-2B chapters 1 and 2 and
AC 43.13-1B chapter 4
• Allow a minimum clearance of 3.0 inches between the connector end of the GEA 24 and any
structures for proper wire harness routing
• Maintain a maximum load capacity of 3.0 lbs
An example of the support bracket for a GEA 24 is shown in Figure 4-43.
