Autopilot failure on ILS approach

[robs2107]

This Royal Flying Doctor Service PC-12 had flown from Alice Springs and was on an ILS approach into Adelaide when the Autopilot gave up. The plane would have had single pilot (after the Autopilot failure definitely a single pilot). I don't know if they had a patient in board but if they did, I'm sure the alarms would have caused them some concern.
