On my two visits to Bankstown I saw a Skyvan registered as VH-IBS but they were different aircraft. Registered as G-AYZB before delivery to Pelita Air Service as PK-PSA in 1971. To Royair International in 1986. Sold as N8189J in 1989. To International Aviation as 9M-BAM in 1998 then to Horizon Airlines as VH-IBS in 1999. Sold in 2004 then sold as 4X-AGP in 2012.
