I think way too many people are getting too comfortable with the idea that a bunch of electric motors are completely safe for air travel. That the in lab and test phase failure rate is so low that no need to worry......
I was in hueys (Don should remember this) when the Blackhawks were accepted and they told all us huey guys we had to transition (I was smart and when to Chinooks). Well wasn't a few months in service when we started seeing the yard darts diving in.......yep small electrical problem with the stabilator going full down on it own un-commanded. Couldn't stop it either. Well no one could admit to design flaw, lots of excuses about radio, radar, microwave etc interference causing the problem.
So the fix, well a trigger that kills power to the stabilator trim system. No fix because they never really knew why it happened.
Airbus installed a real system reset, did not fix their problem either.
The more complicated, they more sub-system controllers, they more loaded digital controlled systems they more they miss and they more problems show up totally unexpected when the un-tested scenarios finally show up and scare the total shit out of the operator or kill him.
The fix, well as history shows it will be a KILL switch or a RESET button.
