On 10 November 2023, an Airbus A320 inbound to Delhi going around from an approach to runway 29L came into close contact with a Boeing 787-8 which had just taken off from the closely-spaced parallel runway 29R whilst they were on different frequencies. Two successive TCAS RAs occurred and were followed which prevented a collision. Prior to that point, both aircraft had been flown in accordance with their clearances. The conflict occurred because the aircraft flight paths as cleared created a collision risk. Inadequacies in related ATC procedures and practices and in controller performance and support were assessed as causal.
