of overhaul and test work on the Rolls-Royce Kestrel engine. His duties were expanded with his March 1941 promotion to include the overhaul, inspection and testing of both the Kestrel and Rolls-Royce Merlin aircraft engines. In August 1941, McAloney was posted to the Directorate of Equipment at RAAF Headquarters, Melbourne. In this capacity he advised on the procurement of equipment and spare parts for RAAF aircraft. He was further tasked with compiling a register of aeroplane equipment at RAAF flight training units and operational bases throughout Australia. The latter entailed McAloney visiting several Air Force units in Victoria, New South Wales and Queensland to check equipment stores. On 1 March 1942, he was commissioned as a flying officer. Transferred to the Directorate of Equipment Administration in July, McAloney was made Officer Commanding Technical and Photographic Staffs and served as a liaison between his own directorate and that of Technical Services. Promoted to temporary flight lieutenant on 1 August 1943, McAloney was sent to the Directorate of Technical Services from November as the specialist officer on American and gas turbine jet engines. The following November, he was dispatched to Dutch New Guinea to rectify issues being experienced with Pratt & Whitney engines in operations by aircraft of the 1st Tactical Air Force. He returned to Australia and his position with Technical Services in December, and saw out the remainder of the war in this post. McAloney decided he wanted to remain in the Air Force on the cessation of hostilities, and subsequently sought a permanent commission in the post-war RAAF. Having continued on a short-service commission in the meantime, his application was ultimately approved in September 1948 and he was granted the substantive rank of flight lieutenant. His younger brother, Robert Simpson McAloney, also saw service with the RAAF in the Second World War. He had enlisted in late 1937 and rose to the rank of warrant officer before his discharge in 1946, his final posting being to No. 1 Communication Unit. Post-war and senior engineering officer In mid-1946, McAloney was involved in an investigation into a series of engine failures experienced by RAAF aircraft. The inquiry led him to visit operational and transport units throughout Australia, in an attempt to determine whether the issues were the result of substandard maintenance or defective components. He returned to his duties at the Directorate of Technical Services on the investigation's conclusion. Made squadron
