Figure 4-3 Front and Rear Mounting Bracket
Electrical bonding must be carefully considered when installing the mounting bracket to the instrument
panel, as this is the primary grounding mechanism for High-Intensity Radiated Fields (HIRF) and lighting
protection.
The mounting bracket must remain un-painted and be bonded to the aircraft frame (or equivalent for
composite aircraft) with a resistance of 2.5 milliohms or less. This can be achieved by cleaning and/or
removing paint from the rear side of the instrument panel where the retaining nuts make contact with
the panel structure.
