4.5 System Status Page
The System Status Page on the MFD provides LRU health status by means of a green
check mark or red X indication (see Figure 4-3). Software versions are listed for installed
LRUs, along with other database versions and dates. If a red X is shown for an LRU,
refer to the associated troubleshooting information in Section 4.7.

4.6 Visual Inspection
Conduct a general visual check of all LRUs and associated wiring harnesses to ensure
continued installation integrity. Inspect all LRUs for security of attachment, including
visual inspection of mounting rack and other supporting structure attaching the rack to
aircraft structure. For installations using countersunk fasteners, verify the fastener heads
are in full contact with unit mounting rack holes.
Re-torque mounting fasteners to aircraft specifications if required. Inspect for signs of
corrosion. Inspect condition of wiring, shield terminations, routing, and attachment/
clamping. Inspect any bonding straps for corrosion, loose connections, or signs of
lightning damage. Rework as needed. Ensure the appropriate circuit breakers are
closed.
Perform a visual inspection of avionics fan operation. Check fan wiring. Visually inspect
integrity of the system antennas, antenna fasteners, and antenna sealant for damage. If
required, check and re-torque antenna fasteners 20 to 25 in-lbs, and remove and replace
antenna sealant. Perform any Periodic Maintenance visual inspections listed in Section
8.
