The Australian Transport Safety Bureau (ATSB) is investigating two separate flight below minimum altitude occurrences 40 km south of Cairns Airport, Queensland. The first involved a Virgin Australia Boeing 737, registered VH-VUT, on 24 October, and the other a Qantas Boeing 737, registered VH-VZA, on 26 October 2022.
In both occurrences, the aircraft were following a standard arrival route (STAR), when they were inadvertently descended below the minimum safe altitude. On each occasion, air traffic control identified the aircraft's descent and alerted their flight crew. The flights in both cases were then completed without further incident.
This one certainly been kept quiet. Looks like similar behaviour in both, ie intercepting HENDO incorrectly instead of 6800. Having a quick look at the archives online, QF approaching HENDO from the east was visual at all times with the terrain, velocity certainly wasn't who came from the south in darkness and low cloud. Listening to that tape replay wasn't a pleasant experience in the VA case.
