So...
Are any details known on the incident at hand yet? Was it during takeoff or landing? And what about the weather?
The few things that are out until now leave me with a big question mark over my head. It seems that YROM has a 1500m runway, so landing would most likely be done with flaps 35. This in turn makes a tailstrike during flare rather unlikely, as the negative pitch during approach with this setting would rather seem conductive to a nose gear landing. Takeoff on the other hand... from my experience, the -400 is not really prone to overrotation, and on a 1500m runway the approaching runway end should still be far enough away not to scare even a low-time colleague into yanking the nose up too rapidly on rotation.
