I'm not knowledgeable on the ERJ series of aircraft but I'm curious if they are possibly susceptible to the same inner turbine icing that the JT15D-5's on the Beech 400A experienced. If I recall the Beech Jet's suffered some dual engine flameouts back in the early 2000's while operating in the vicinity of convective buildups. It was found that ice crystals thrown off by the buildups would cause the icing and lead to engine failure.
Someone correct me if I'm wrong, it's been a while.
