| Executive Summary: | An Air New Zealand B737 was on final approach to runway 16, at Wellington Airport when a Piper PA38 Tomahawk was cleared to cross from Wellington City to Petone, maintaining visual separation. The aircraft converged until a loss of separation occurred. Both aircraft were flying in visual meteorological conditions (VMC). The pilot of the Tomahawk attempted to take evasive action. The aircraft passed in opposite directions with about 350 m between them. None of the 68 persons on board the aircraft were injured. [...] This airmiss resulted from a system of ATC clearance with visual separation which was not in accordance with the Manual of Air Traffic Services, but was approved by the Airways Corporation. Had the prescribed procedures been followed, the pilot of the Tomahawk would not have had the opponunity to make an erroneous judgement that he could pass safely in front of the airliner on final approach. Contributing factors included inadequate surveillance of the Airways Corporation's operations by the Air Transport Division, and lack of specific review and preventive action following earlier airmiss incidents. |
