to mark its retirement from that base. The last military flight was on 27 April 1959 when CA-16 A20-686 was flown to Tocumwal for disposal. In 1954, Super Spread Aviation, based at Moorabbin Airport, bought two CA-16 Wirraways and modified them to perform aerial application operations. Both were almost brand-new, one having flown 9 hours and the other 12 hours; the modifications included the fitment of a hopper and spraying equipment. In a reflection of much of what was asked of the type during wartime, the two aircraft proved to be inadequate for the task and both were de-registered on 10 April 1956 and later scrapped. Despite the scrapping of these two aircraft and hundreds of others, a healthy number of Wirraways survive today, in aviation museums in Australia, Papua New Guinea and in the United States; and with 10 on the Australian civil aircraft register in 2011; either flying or under restoration to fly as warbirds. A Wirraway being operated as a warbird crashed during an airshow at Nowra in 1999, killing the two occupants. Variants CA-1 "Mk I" Initial contract variant. 40 built.
