VH-AVS was one of several Aerostars used to deliver documents from Sydney to rural bank branches. The ability to safely remove satchels from the baggage locker of an Aerostar without shutting down the engines was an advantage in the quick turnarounds needed. In the late afternoon the aircraft retraced their route collecting the day's business papers.

Reregistered VH-WRF in 1997

Stalled and crashed turning final at Lismore, NSW, March 3, 1986

The Aerostar was designed by Ted Smith whose company was taken over by Piper in 1978. BSL / MLH is a strange airport, with miles of fencing separating Swiss and French facilities and roads because Switzerland is not in the EU.
