I was thinking more of the ADIRU manufacturer?
BTW FlyBoy, as you've decided to pollute this discussion, you might like to know that your dogmatically chosen manufacturer of choice has had similar problems....
Boeing 777 loses vital flight air data, SAARU, ADIRU, Australian Air Safety Investigation, B-777 fly-by-wire
but don't let a complete lack of knowledge about aircraft, computer systems, theory and practice of safety-critical systems, piloting stop you from making stupid, brain dead commments...
