Recorded during the middle of 2001, a Kendell Airlines CRJ 200 registered VH-KJF (callsign Kilo Juliet Foxtrot) operating a flight between Melbourne and Tasmania declares pan following the failure of a hydraulic system over Bass Straight.
Several weeks earlier another Kendell CRJ 200, registered VH-KJG flying a similar route also made a midair return to Melbourne after a temperature probe heater became unserviceable.
I've attached both audio files separately.
