Just reported on Aero News Net: Another Cirrus deployed it's chute when ALL
OF THE ELECTRONICS went out leaving the pilot stranded above an overcast...
The article cites recent maintenance of some sort... The issue here is
having all your eggs in one basket... I betcha the factory will say that it
is impossible for everything to fail at once - apparently they never met
Bubba the Mechanic... and just wait till you have your FADEC go poop on
take off...

Once all the magic smoke leaks out of those electronic chip thingies, life
is a bitch... Do not bet your life with a GA airplane that has a total
electronic panel... You still need a few steam gauges, and a spare
nav/com/ils on the back up battery, and at least one vacuum gyro...
