I read that article, and another that gives the same content, plus a lot more background material:
https://interestingengineering.com/b...roblems-to-faa
One whistleblower reported to the FAA that they had seen damage to the electrical wiring connected to the plane’s angle of attack sensor from a foreign object, which feeds data to the MCAS system so it can determine whether it needs to engage to prevent the plane from stalling.
Neither article gives sufficient detail to interpret properly, in the context of the detailed system understanding of MCAS and the cutoff switches discussed elsewhere. The stories seem to muddy the waters, create uncertainty, and may or may not be relevant.
