Status: Active
Investigation in progress


The Australian Transport Safety Bureau has commenced a transport safety investigation into a flight below minimum altitude involving a Beech Aircraft Corp 95-B55, registered VH-ALR, that occurred on approach to Parafield Airport, South Australia, on 12 August 2022.

At about 1300 local time, the pilot of VH-ALR was conducting an RNAV (GNSS) approach for runway 21R in instrument meteorological conditions. The aircraft descended below the segment minimum safe altitude (3,000 ft) as it approached the intermediate approach waypoint.

The approach controller responded to a system-generated minimum safe altitude warning and coordinated with the tower controller to issue the pilot a safety alert. The pilot initiated a climb to correct the profile and then continued the approach. The aircraft landed without further incident.

Should any critical safety issues be identified at any stage during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate safety action can be taken.
