Summary

The ATSB is investigating a near collision involving Cessna 210, VH-SYT, and Cessna 206, VH-HPA, 46 km south-west of Darwin Airport, Northern Territory, on 6 December 2017.

The Cessna 206 departed from runway 18 at Darwin Airport shortly before the Cessna 210 departed from the same runway. The aircraft were operating under the visual flight rules. Air traffic control cleared the pilots of both aircraft to track direct to Port Keats at 8,500 ft. About 46 km south-west of Darwin, the Cessna 206 was maintaining a revised cleared altitude of 6,500 ft, and the Cessna 210 was on climb passing 6,400 ft, when both pilots reported losing sight of the other aircraft. The aircraft passed each other in close proximity. Neither pilot took evasive action.   

As part of the investigation, the ATSB will interview the flight crew and air traffic controllers, review air traffic control radar and audio data, and gather additional information.

A final safety report will be released following the conclusion of the ATSB’s investigation. Should a safety issue be identified during the course of the investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.
