Two aircraft made contact with each other on two separate occasions, 15 February 2019 and 9 July 2019, during a pushback manoeuvre. The ISMS partners investigated the accidents. We have set up a task force to develop any possible measures to prevent this type of accident in the future. The task force has implemented two measures to prevent pushback accidents in the future by changing the long pushback procedure and the responsibilities of the ground controllers and the pushback drivers. The specific pushback risks have been brought to the attention of the drivers and controllers and we are currently developing and implementing additional measures.
