The 340 sounds like the cvfdr or whatever wasn't fitted correctly, ie the retaining nuts failed to engaged. The other two I would guess at the G switch tripped. Can't remember what value they trip at but on helicopters a good slap would switch off the cvfdr. I would guess it would be less for fix wing.
