At about 1735 hours on Monday 2 June 1997 a loss of separation occurred between an RNZAF Hercules and an Eagle Air Metroliner proceeding in opposite directions on the Hamilton - Taumarunui track. The aircraft were under radar control and the Area Controller had cleared the northbound Hercules to descend from flight level 170 to 10 000 feet after the crew reported a pressurisation difficulty. The aircraft passed approximately 0.7 nm horizontally and 600 feet vertically apart.
No deficiencies were identified in relation to established standard procedures for radar control. However the incident underlined the safety benefit likely to ensue from the installation of a system software modification to provide an on-screen alert to controllers of an impending loss of separation and the importance of appropriate track and profile monitoring to ensure separation standards are maintained.
