The instructor pilot was being checked by the club chief flying instructor (CFI). After completing some work in the local training area the aircraft was returned to the circuit area where the CFI took over the controls so that the instructor-under-check could demonstrate his instructional technique. As the aircraft approached the ground for the first landing the instructor told the CFI to "round out and hold the aircraft off". The CFI pulled back on the control column but the rate of descent was not fully arrested and the aircraft touched down heavily and bounced. The CFI pushed the control forward and the aircraft touched down again and bounced. The control column was again pushed forward and the aircraft again bounced after touching down. The aircraft then landed in a nose-down attitude and the left landing gear leg failed. The aircraft slid about 10 metres before coming to rest. This accident was not the subject of an on-site investigation.
