Not sure if this is the time or place for this, but…. According to the ATSB report, the most likely cause of the Tasair accident is that the PIC had received insufficient training, on the part of the operator, on the various types of autopilots TASAIR had installed on their Aero Commanders. As a result it wasn’t disengaged correctly and resulted in a trim runaway type situation. The end result was a negative G overstress. It will be interesting to read the preliminary on this accident.
Condolences to all those affected by this accident.
