Two men were killed and three injured when one of No. 4 SFTS's Ansons crashed after colliding with trees after takeoff at a satellite airfield on 21 July 1943; one of the injured died later without regaining consciousness. Four occupants of an Anson were killed on 1 November, when a wing disintegrated after the pilot apparently became disorientated in cloud and the plane went into a high-speed dive. By the end of the year, flying at No. 4 SFTS had begun to taper off, and it was reduced still further in 1944. Training at the school concluded in December that year, under a reorganisation of EATS establishments in Australia. No. 4 SFTS began disbanding in January 1945, as part of a general reduction in RAAF flight instruction owing to a surplus of trained aircrew, and the task was complete by May. It had graduated over 1,000 pilots—among them Dave Shannon, awarded the Distinguished Service Order for his part in the Dambuster raid by No. 617 Squadron RAF in May 1943—and established, according to the RAAF Historical Section, "an enviable safety record".
