Lonewolf #1672, as yet we do not know what trouble shooting was performed or rectification completed, save a report of a new AoA sensor.
My post #1650 raised questions about AoA malfunction indications, where some aspects could direct maintenance toward AoA and Airspeed vice trim and control. These aspect or similar would support previous pilot reports of airspeed problems and maintenance logs relating to AoA, vice an (unidentified) trim problem.
It might even be possible for an intermittent AoA fault to remain isolated from MCAS, no trim movement etc; or alternatively with trim problems, no knowledge of which AoA sensor was at fault, save detailed information linking vane side with stickshake side. Plenty of room for ambiguity, engineer-pilot liaison, weak/non existent technical-flight manual information … …

It would be interesting to know what Boeing records show of fleet wide maintenance, fault finding, or component change, in these areas. Similarly to hear of any operator problem in these areas, and how the problem was identified and rectified, presumably without grounding the aircraft.

New AoA vane manufacturer, new part number on the 737 Max ?? Just a thought.
