Allison Engine Testing Stands by servicemen of the 44th Depot Repair Squadron of the USAAF 81st Air Depot Group; two enclosed engine stands constructed by the Allied Works Council; two open stands of unknown construction; and a concrete pavement area which is the site of former associated buildings. The first Allison Testing Stands were constructed on the eastern side of Schneider Road and the Eagle Farm Aerodrome in November–December 1942 as a consequence of arrangements made for Australia to serve as a stronghold for United States (US) operations in the Pacific during World War II (WWII). The area, however, had previous links with aviation.
