After all, the Laudair accident was - in fact, not opinion - a FADEC accident so the theory of steel cables and the dumb Boeing vs. Airbus argument went out the window decades ago.
I think the 1991 Lauda air crash in Thailand was the result of an uncommanded inflight reverser deployment. The EEC on the left engine went to idle as designed with the T/R deployment. Not sure how you would call it a FADEC accident.
There was some controversy about the electrical control of the T/R's on the PW4060 engines compared to the earlier JT9D's with hydromechanical control. Is this perhaps what you are referencing?
