Why can't people accept the Boeing and RR findings and recommendations?
They are no more than interim.
They used non-representative fuel, and unless they are being very odd haven't managed to recreate the problem using representative fuel (anyone know ?)

In addition, the new fuel/ice behaviour needs examination and new rules written - AND all engine/fuel installations need to be examined against the [future] new rules. There may be more aircraft at risk than we know.
