A heavily modified Chipmunk intended for low-level aerial cattle mustering with metal-skinned wings and powered by a 180hp Lycoming engine. Aerostructures had previously converted three Chipmunks to single-seat cropdusters while retaining the Gipsy engine. It also converted another Chipmunk to a Lycoming engine for aerobatics. While the others received Australian approval, VH-CXZ was rejected and it was shipped to the US where it became N8DW.
