This looks terrifying. I wonder if anyone knows more about this. From the rough translation from Google I understand that they lost (all?) instruments and (some?) controls and that F16s intercepted them to assist with a landing at Beja airport. They were even considering ditching at some point?
From the maneuvering in the picture below I am amazed how they even regained control of the aircraft. The passengers must have experienced some serious Gs.
Mayday call at 3:57: http://archive-server.liveatc.net/lppt/LPPT-App-1191-2-Nov-11-2018-1330Z.mp3
I trimmed out the audio and used high-pass filter on parts with loud low frequency noises. It is clear now that they could not control the airplane. Cred to the pilots for not crashing after 2 minutes! Here is the audio:
Would they not normally take the Mayday to a discrete frequency?
Maybe they lost everything and could not change frequency? Or simply the ATC didn’t want to overload them.

My understanding (from another forum) is that ATC switched everyone else to another frequency. In any case – this must have been some horror ride ! Amazing job by the pilots, glad they made it down safely.
Scary event. Glad they made it.
Claims on PPRuNe that the aileron controls were reversed.

If that is the case, it could have been spotted with proper preflight checks. I always stop for a couple of seconds and think of which direction should my ailerons turn during the preflight checks. I started doing this after reading about a fatal GA accident due to this, cannot find reference right now.
I don’t think the pilots can see the control surfaces from the cockpit.
However, is this a FBW aircraft? If so, it would perhaps have some position feedback from the control surfaces. Or maybe it is totally open-loop? That would surprise me…
There are videos of reversed control surface crashes (on non-FBW aircraft) and they usually happen immediately after takeoff.
