AO-2023-008 Close proximity incident involving Q300, ZK-NES and Beech 76 Duchess, ZK-JED, near Brynderwyn, 28 August 2023

The reported circumstances were that at about 1000 on 28 August 2023 an Air New Zealand Q300 passenger aircraft ZK-NES, was en route from Whangarei to Auckland, and a Beech 76 Duchess aircraft ZK-JED, was en route from Auckland to Whangarei. 

The two aircraft were on reciprocal tracks when a close proximity event occurred. The crew of both aircraft attempted to coordinate avoiding action and this subsequently resulted in the flight crew of the Q300 receiving a momentary Traffic Alert and Collision Avoidance System (TCAS) Traffic Advisory. 

There was no collision, no damage, and nobody was injured.
