Hi,
DW
As yet, we don't know which model was fitted to the aircraft in this incident, but it appears that the EAD is causing a review of this new design and a fix should be in the works.
Long ago (you made yourself note) probes are prone to icing or blocking by ice particles and since that time there has been no suitable solution found and I think it will not change until prohibit aircraft from flying in icing environments or equip each sensor with a flamethrower
