never been needed by any other aircraft in airline service in Australia, to my knowledge
The Dove wing failures were down to the selection of the wrong spec material for the spar booms.Following a wing failure at Kalgoorlie the ARL determined the safe life to be 3,000 hours using the then new 75ST alloy which the Dove employed. Reverting to the 24ST material used in many designs would increase spar life by an estimated three to five times. At the time little was known about fatigue in metal aircraft structures and the Kalgoolie accident was a seminal event in understanding, and the impetus for research. Likewise, the Vickers Valiant bombers early retirement from service was due to fatigue issues resulting from being built from the wrong spec material.
