Bearing in mind that neither of the reports have been published yet, it would be safer to say that on the 737 MAX an AoA
indication failure (not necessarily involving a defective vane/transmitter)
may (depending on the magnitude and sense of the resulting error) trigger MCAS.
Out of interest, before the grounding were there any recorded instances of a more benign air data failure on a MAX, obviously without producing the JT/ET result ?
