In Allied hands
During late September 1943 Lae was captured by the Australian Army and the area was occupied by the Allies whereupon the aircraft was found. Afterwards, this aircraft was disassembled and shipped to Brisbane and transported to Hangar 7 at Eagle Farm Airfield, where the aircraft was reassembled and restored to flying condition by the then Air Technical Intelligence Unit (ATIU) that operated out of Hanger 7 at Eagle Farm Airfield, using parts of the various airframes named earlier. When ready, it was flown and tested as XJ002 at Eagle Farm Airbase, Brisbane, Queensland, Australia.
While being restored, most of the green paint was stripped off to bare metal. After restoration, the aircraft was painted green with U. S. markings and tail code XJ002 in black on both sides of the tail. Later the aircraft was repainted in japanese markings for recognition manual purposes.
On March 17, 1944 this aircraft was test flown by USAAF test pilot Captain William O. Farrior for 25 minutes. On March 18, 1944 test flown for 55 minutes. Afterwards, the fate of this Oscar is unknown.
