1 question
Which aircraft variant are you troubleshooting?
2 action
Use this maintenance guide to locate the Ethernet harness and connectors that should be inspected for this link fault.
Please read the checklist carefully, refer to the layout diagram and then proceed with the debugging steps below.
Make sure to check Zerp for any recently replaced HW. If any LRU was recently replaced, proceed with inspection or replacement of remaining LRUs in the list.
LRUs to check:
- Hover-SA to Distro flex harness.
- Hover-SA board and connector.
- Distro to Hover-PA flex harness.
- Hover-PA board and connector.
- Distro board and connector.
Please read the checklist carefully, refer to the layout diagram and then proceed with the debugging steps below.
Make sure to check Zerp for any recently replaced HW. If any LRU was recently replaced, proceed with inspection or replacement of remaining LRUs in the list.
LRUs to check:
- Hover-SA to Distro flex harness.
- Hover-SA board and connector.
- Distro to Hover-PA flex harness.
- Hover-PA board and connector.
- Distro board and connector.

4 question
Inspect the hover SA flex, is there any visible damage?
5 action
Swap the hover SA flex and proceed to the next inspection steps.
6 question
Inspect the hover SA motor (especially the connector), is there any visible damage?
7 action
Swap the Hover Stbd Aft motor, proceed to next inspection steps.
8 question
Inspect the hover PA flex, is there any visible damage?
9 action
Swap the hover PA flex and proceed to the next inspection steps.
10 question
Inspect the hover PA motor (especially the connector), is there any visible damage?
11 action
Swap the Hover Port Aft motor, proceed to next inspection steps.
12 question
Inspect the distro (especially the connector), is there any visible damage?
13 action
Swap the distro board, proceed to next inspection steps.
14 question
Was anything swapped due to damage?
15 action
Invisible damage is most likely in one of the flexes. Swap both implicated flexes (make sure the replacements have the foam covering). Notify and ship the removed flexes to Avionics-HW-on-call POC (and include Joseph Katz). Try a redocking flight.
16 question
Is the issue resolved?
17 reference
The Aircraft may return to service.
18 escalation
Escalate to P2 Avionics Hardware On Call.
