Not a great audio file as the radio kept switching between frequencies during the incident. However, it's something that happened at Victoria, which is pretty rare (thankfully). I've edited the file to only those involved in the incident.
From the CADORS...

The occurrence aircraft's engine was equipped with a single spark plug per cylinder.
