We know the engine was operational at the time of impact. This is because the prop was not in a freathered position. At least postion of the condition levers may have been in two possibly positions of grd idle of 52% or flight idle of 72% ng. It should be at the later. At in 72% it would not have zero tq. This is the min speed of the N1 if the power lever is brought back to the idle position.
With out oil px the prop will not and cannot stay in fine pitch.
In this case the posibity of auto freather may or may not have worked. Auto freather only purpose is to help the pilot from removing power from the wrong engine if there is a problem. If the engine has a completely lost power from the cold section it will freater its self.
It can be seen from the pics that one of the engines was not in the freathered position. We at this stage ate only think it was the left engine which has had the problem. Astb reports say that both engines internal assy where operational.
