While the aircraft was being turned left to line up on a runway situated on a black soil plain, the right mainwheel broke through the runway surface, dropped into a concealed hole beneath the crust and bounced out again. The pilot shut down the engines and after inspecting the aircraft elected to fly it to Alice Springs. On arrival the aircraft was placed unserviceable. An inspection by an engineer revealed that the right maingear had been displaced rearward, the gear support structure buckled and the right engine was found to droop 1.5 centimetres.
