The ATR 72 600 is a twin-engine turboprop, short-haul regional airliner has been involved in 66 aviation accidents and incidents including 39 hull losses, resulting in 440 fatalities since its inception in 2007.
Interesting point is that the aircraft is capable of flying for around 2 hours with only one engine performing. So this could most likely by pilot error with an instructor in the left hand seat.
There was a call from the aircraft according to the article, and another I found, that said the pilot was requesting a runway change in what appears to be downwind position. The reason was not identified where I can find it discussed.
There are current orders for 50 of these aircraft from FEDEX for their US based fleet.
