Taking Apart Two TTSB Crash Reports: Neither Was the Operator's Fault
Only four drone occurrences have entered Taiwan's official aviation safety statistics — because the threshold is 'substantial damage to a drone over 25 kg.' A hobbyist crash never enters the count. The two published investigation reports are the same model, the same manufacturer, and the same agency, and both probable causes were hardware failures: main rotor servo electrical failure in one, a fractured tail rotor pitch link in the other. In both, the flight control computer and the operator were explicitly cleared.
