Quotes from link above:
As for the Air France crash, in which it's believed 228 tragic souls perished in the sea off Brazil, the Airbus 330 involved reportedly transmitted warnings to Air France maintenance that its ADIRU was not functioning properly.
Also last year, the U.S. Federal Aviation Administration issued an Airworthiness Directive warning airlines about an "unsafe condition" associated with ADIRU's aboard Airbus 319, 320, and 321 models.
And the fact is, wonky ADIRUs have been identified as the culprits in several recent near-catastrophes. Last year, for instance, authorities blamed the ADIRU after a Qantas Airbus 330 started porpoising wildly while at cruising altitude. There were 51 passenger injuries, ranging from broken bones to spinal damage, before pilots regained control.
