Hello nrp,

I realize that this particular failure sounded like a vibration
problem, but a few more isolating and shunting diodes in our
electronics would seem to help reliability a lot.



And some ferrites which can be awesome protection for the electronics in
case you get into that surprise thunderstorm.

When debugging EMI in a composite structure back in the 80's I was
mighty disappointed with the EMI susceptibility of some NAV/COM gear.

Regards, Joerg
