On February 15 and July 9, 2019, two aircraft had a collision during a pushback manoeuvre. ISMS partners jointly investigated these pushback accidents. The task force has implemented two measures which prevent pushback accidents. The long pushback procedure was refined and the responsibilities of the ground controllers and the pushback drivers were clarified. Further mitigations are considered. A possible adjustment in the pushback procedure is investigated, with the new roadmap item 38. Fixed pushback release points. The implementation date above refers to the safety improvements which are currently being implemented. For the safety improvements which are currently in study, the implementation date might be updated.
