There are some distinct questions/problems that are legitimate but thrown into a blender.
- Manufacturing problem with the Lion Air original AOA-Sensor and no known to the public measures derived from it.
- Unknown root cause of Ethopian AOA sensor failure (who tried to attribute it so a bird strike? I honestly can't remember.)
- Obvious E/E deficiencies on both new aircraft that could not be diagnosed and sorted out by local maintenance.
- The usual business of manufacturing problems, not only the MAX suffers from.
Maybe the more appropriate headline with regard to those problems would be Boeing - Still not fixed.
No, I don't think the MAX is fixed, but that is due to yet another balcony, another warning, another algorithm and tons of MEL items, Check list entries added to 60ies ramshackle base structure.
