The ATSB is investigating a separation issue involving a Piper PA-28, registered VH-TAX and a The Airplane Factory Sling 2, registered VH-ZSD, at Moorabbin Airport, Victoria, on 23 July 2020.

While the Sling 2 was on the base leg of an approach to runway 17 left for a touch-and-go, the Piper was instructed to line up on the runway. As the Piper was in the lined up position, the Sling 2 overflew the Piper and landed on the runway.
