That incident was caused by corrosion on the horizontal stab trim control unit (HSTCU). There were several similar incidents, which triggered the AD mentioned earlier in this thread. That AD required replacement of the HSTCU with ones that had a conformal coating on the circuit board, to prevent such corrosion. Thus this accident should not have been caused by the same problem.
