So now both accident investigation teams will teardown both accident's engines to determine just what goes wrong in this model engine to leave the fan blades looking so good but resulting in a near total thrust loss nevertheless.
I know for a fact that these engines have a very sharpe leading edge to the fan-blades ( I have cut my hand carrying out an inspection of them) Unlike for example the RB 211 fan. I would suspect therefore that a large quantity of diced bird remains doesn't do the core airflow characteristics much good.
