Perhaps it doesnt receive the same attention as it operates mostly cargo based flights now ?
From the maintenance standpoint...hardly likely.
Perhaps the problem lies with the crew trained to fly the airplane....the MD11 clearly requires a high level of crew attention/experience, perhaps the latest idea of dumbing down crew with minimal training and/or experience is beginning to take its toll.
Wait for the final report...it will tell the tale...in the mean time, all other scenarios are simply guesswork...including this one.
