The torque set on the approach seems surprisingly low to me - is the 24% that it was increased to at 80kts, having previously been just 18%, anywhere near what the crew might have expected would maintain an 80kt 500ft/min approach profile?
Very sadly for the crew, there seems to be no information coming from either this report, or any reported comments from them on the accident, that looks like this was anything other than simple (two) pilot error from a bizzarely very poorly monitored approach. For their sakes I had hoped there might at least been distraction from dealing with some warning captions or other cockpit distraction.
