The following is the ACARS messages received by Air France. They are time stamped plus annotated FLR (Fault Report) and WRN (Warning).



This is a breakdown of the ATA listings for the relevant messages:

34-22-25 - INDICATOR - ISIS (INTEGRATED STANDBY INSTRUMENT SYSTEM)
34-43-00 - TRAFFIC AND TERRAIN COLLISION AVOIDANCE SYSTEM
34-12-00 - AIR DATA/INERTIAL REFERENCE SYSTEM (ADIRS) ((ADIRU & CDU))
34-10-00 - AIR DATA/INERTIAL REFERENCE SYSTEM (ADIRS)
27-90-00 - ELECTRICAL FLIGHT CONTROL SYSTEM (EFCS)
22-83-34 - FMGEC (FLIGHT MANAGEMENT, GUIDANCE AND ENVELOPE COMPUTER)
22-62-00 - FLIGHT ENVELOPE COMPUTATION
22-30-00 – AUTOTHRUST
27-23-00 - RUDDER AND PEDAL TRAVEL LIMITING ACTUATION
27-93-00 - FLIGHT CONTROL PRIMARY COMPUTER (FCPC)
34-11-15 - PROBE – PITOT
27-93-34 - FCPC (FLIGHT CONTROL PRIMARY COMPUTER)
21-31-00 - PRESSURE CONTROL AND MONITORING
27-91-00 - OPERATIONAL CONFIGURATION (F/Ctl Altn law)

Here is the list of faults in the order they occurred: Not official this, it's from a LAME however.

02:10Z:
Autothrust off
Autopilot off
FBW alternate law
Rudder Travel Limiter Fault
TCAS fault
Flight Envelope Computation warning

02:11Z:
Failure of all three ADIRUs
Failure of gyros of ISIS (attitude information lost)

02:12Z:
ADIRUs Air Data disagree

02:13Z:
Flight Management, Guidance and Envelope Computer fault
PRIM 1 fault
SEC 1 fault
02:14Z:
Cabin Pressure Controller fault (cabin vertical speed)

Informed speculation on the thread is that the A/C may have suffered a triple ADR failure, perhaps as a result of icing. This would have caused a loss of all primary flight instruments and for some reason the ISIS (standby instruments) were also affected

The following is a list of affected systems from the loss of all ADR's checklist.

F/CTL PROT (Alternate Law)
ADR 1+2+3
L/G RETRACT
AP 1+2
A/THR
RUD TRV LIM
WINDSHEAR DET
CAB PR 1+2
GPWS

OTHER INOP SYS
FLAPS AUTO RETRACT
ALPHA LOCK
FLAPS LOAD RELIEF
ATC ALTI MODE TCAS

HSLD
