Thanks MechEngr. I was thinking that the initial problem was some considerable years ago, plenty of time for a fix to have been developed.
I suspect that the report into this event is going to be uncomfortable reading for someone or other.
One thing does occur though. If the fix has been available for 5, 6 years and hadn't been installed, there's been enough time for this behaviour to have occured 7 or 8 times by now if the aircraft hadn't been routinely de-powered in all that time.
