At 2316:44 UTC
Auto Pilot (A/P) and the Auto-thrust (A/THR) disengaged.
Flight control law reverted from Normal Law to Alternate Law.
The aircraft started to roll to the left up to 54° angle of bank.
Nine seconds after the autopilot disengaged, the right side-stick activated.
The aircraft roll angle reduced to 9° left and then rolled back to 53° left.
The input on the right side-stick was mostly pitch up and the aircraft climbed up to approximately 38,000 feet with a climb rate of up to 11,000 feet per minute.
2317:18 UTC
The stall warning activated and at 2317:22 UTC stopped for 1 second then continued until the end of recording.
The first left side stick input was at 2317:03 UTC for 2 seconds and at 2317:15 UTC another input for 2 seconds, then since 2317:29 UTC the input continued until the end of the recording.
The right side stick input was mostly at maximum pitch up until the end of recording.
The lowest ISIS speed recorded was 55 knots. The ISIS speed recorded fluctuated at an average of 140 knots until the end of the recording.
2317:41 UTC
At 2317:41 UTC the aircraft reached the highest ISIS altitude of 38,500 feet and the largest roll angle of 104° to the left. The aircraft then lost altitude with a descent rate of up to 20,000 feet per minute.
At approximately 29,000 feet the aircraft attitude was wings level with pitch and roll angles of approximately zero with the airspeed varied between 100 and 160 knots.
The Angle of Attack (AOA)5 was almost constant at approximately 40° up and the stall warning continued until the end of recording.
The aircraft then lost altitude with an average rate of 12,000 feet per minute until the end of the recording.
2320:35 UTC
The last data recorded by FDR was at 2320:35 UTC with ISIS airspeed of 132 kts, pitch 20° up, AOA 50° up, roll 8° to left, the rate of descent 8,400 ft/minute and the radio altitude was 118 feet.
My Initial Simple Summary:
Systems malfunctions led to FO conducting unintended zoom climb to LOC, then held full back stick all the way down.
Verdict:
AF-447 Mk2
