According to Afriqiyah, the crash took place at 4:00 UTC
Afriqiyah Airways ,Announce that our flight 8U771 had an accident during landing at Tripoli International airport at 04:00 UTC. (06:00 AM Tripoli time) Today Wednesday 12 May.
The active metar at that time was
Hllt 120350z Vrb01kt 6000 Nsc 19/17 Q1008
or even
Hllt 120250z 35003kt 6000 Skc 19/17 Q1008
So the crew was expecting with high probability a visual approach, unless warned otherwise by TAF, experience, approach, tower, previous landing traffic or haze visible from above and afar (in darkness).
Does anyone have the active TAF of that moment?
Under above active metar, the choice of runway 09 wasn't all that crazy (apart from sunrise to be expected) if ATC preferred that direction.
This further contributes to my speculation that this was an unexpected instrument approach gone sour.
Niner Mike.
