Use this maintenance guide to locate the Ethernet harness and connectors that should be inspected for this link fault.
Please read the checklist carefully 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-PA to Distro flex harness.
- Hover-PA motor and connector.
- Distro to Hover-PF flex harness.
- Hover-PF motor and connector.
- Distro board and connector.
Please read the checklist carefully and then proceed with the debugging steps below.

LRUs to check:
- Hover-PA to Distro flex harness.
- Hover-PA motor and connector.
- Distro to Hover-PF flex harness.
- Hover-PF motor and connector.
- Distro board and connector.
2 question
Inspect the hover PA flex, is there any visible damage?
3 action
Swap the hover PA flex and proceed to the next inspection steps.
4 question
Inspect the hover PA motor (especially the connector), is there any visible damage?
5 action
Swap the Hover Port Aft motor, proceed to next inspection steps.
6 question
Inspect the hover PF flex, is there any visible damage?
7 action
Swap the hover PF flex and proceed to the next inspection steps.
8 question
Inspect the hover PF motor (especially the connector), is there any visible damage?
9 action
Swap the Hover Port Fwd motor, proceed to next inspection steps.
10 question
Inspect the distro board (especially the relevant connector), is there any visible damage?
11 action
Swap the distro board, proceed to next steps.
12 question
Was anything swapped due to damage?
13 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.
14 question
Is the issue resolved?
15 reference
The Aircraft may return to service.
16 escalation
Escalate to P2 Avionics Hardware On Call.
