SASLESS your back, I have not seen a post from you in a very long time.
Is it not possible the engine failure ( eruption) was after the aircraft impacted the water??
Looking at the pictures of the engine most if not all of the bolts that hold on the power module were gone, indicated they broke. Which could have occurred post crash.
As SAS mentions is quite hard to believe two totally different failures happen at the same time in flight.
