Summary

Perth ATS assigned the aircraft an altitude of FL330 on descent from FL370. However, the radar mode C display of the aircraft showed the aircraft descending through FL330 to a final level of FL323. When the air traffic controller queried the crew, the pilot verified FL330. The mode C readout then showed the aircraft climbing and then maintaining FL330. When the aircraft descended below FL330, a Fokker F28 was at FL310, and positioned 4 NM away.
