A mate of mine was in there recently, judging by his photos you found just about all there is still to find from the plane wreck. There was also the remains of a propeller, just the hub if that's the right word, as the blades are long gone, which I imagine could be walked right past without recognising what it is
Yeah from reports apparently the propeller hub and maybe a wing are closish to the engine. But anything more...might need a whole day and very good searching skills!
Still was a fun trip, and satisfied my curiosity :)
