soem dood:
Thanks for the links.
That is what i wondered years ago as well, at a time when we were confronted with uncommanded closing of main fuel shutoff valves (MFSOV), also a 28v dc system but on a different aircraft type. At the time only the valve was affected, no other 28 v dc system components. Regarding a scenario: EMI does not necessarily imply an external source, in this case it was generated in the connector itself.
Something to add to the history:

With regards to G-YMMM: without the data it remains a theory, nothing more. I do not intend to twist facts to suit theories, it is beter to twist theories to suit facts.
But since i have had first hand experience with a similar issue (as the above links explain), first time it happened it was also thought an impossible scenario, but happen it did.
