One wonders at possible structural integrity degeneration in Australian registered Shrikes, due to the Australian only VFR and IFR maximum gross weights, which are 10% higher than the original FAA certified maximum gross weight? The FAA and manufacturer did not support the Australian increase in MTOW and the manufacturer is on record opposing any change in aircraft weights.
The increased Australian MTOW was obtained by H C Sleigh Aviation, many years ago, on new airframes, for coastal surveillance purposes.
what about VH-YJB, the last inflight break up of a shrike in Australia with a previous life operating in the USA presumably at the FAA MTOW before flying just under 100hrs here? it was also relatively young with around 4500hrs.
