Interesting date on the prelim but here it is at last:

The section most discussed by actual pilots would be:

The flight was initially cleared by ATC on a Lateb 1 D departure from Runway 21. Just before take-off ATC changed the clearance to an "immediate right turn direct Chekka".

The flight took-off at 00:37:08 and just after take-off ATC (Tower) instructed ET 409 to turn right on a heading of 315 degrees and change to Control (ATC) 119.3. ET 409 acknowledged the clearance and heading 315 degrees was selected on the MCP.

ET 409 continued right turn, ATC instructed ET 409 to turn left heading 270 degrees. ET acknowledged and 270 was selected on the MCP. Maximum heading reached prior to left turn was 003 degrees.

ET-409 continued left turn to heading 270 degrees after acknowledgment and continued to a southerly track then on a sharp left turn until it disappeared from the radar screen and crashed into the Mediterranean Sea about 4 minutes after take-off.

The aircraft impacted the water surface at 00:41:30 around 6 NM South West of BRHIA and all occupants were fatally injured. SAR operations were initiated at 00:47:41.

The DFDR and CVR were retrieved from the sea bed and read, as per the Lebanese Government decision, at the BEA facility at Le Bourget, France. The recorders data revealed that ET 409 encountered two stick shakers respectively at time 00:40:01 for a period of 29 seconds and at 00:40:56 for a period of 26 seconds. 10 "Bank Angle" warnings were registered between 00:38:41 and 00:40:54; an over-speed clacker was also registered from time 00:41:25 till the end. The maximum registered AOA was 32 degrees at 00:40:14, maximum registered bank angle was 118 degrees Left at 00:41:14, the maximum registered speed was 407.5 knots at 00:41:28, the maximum registered G load was 4.412 at 00:41:28 and the maximum registered nose down pitch value was 63.1 degrees at 00:41:16.

The DFDR recording stopped at 00:41:28 with the aircraft at 1291 feet. The last radar screen recording was at 00:41:28 with the aircraft at 1300 feet. The last CVR recording was a loud noise just prior to 00:41:30.
