As it fell out of the sky.
"Over a time span of four minutes, starting at 02:10 UTC, a series of ACARS messages were sent -automatically- from the plane. The first message indicated the disconnection of the autopilot followed and the airplane went into 'alternate law' flight control mode. This happens when multiple failures of redundant systems occur. From 02:11 to 02:13, multiple faults regarding the Air Data Inertial Reference Unit (ADIRU) and ISIS (Integrated Standby Instruments System) were reported. Then on 02:13 the system reported failures of PRIM 1, the primary flight control computers that receive inputs from the ADIRU and SEC 1 (secondary flight control computers). The last message at 02:14 was a 'Cabin vertical speed' advisory. " Extract from Aviation Safety Net
