Boeing 777, G-VIIK, collided with a stationary Airbus A321, G-EUXH, whilst being pushed back from its stand at London Heathrow Terminal 4. Moments earlier, the Airbus had taxied behind the Boeing 777 towards its own stand, but had been unable to park because the electronic stand guidance had not been activated. It stopped short of the parking position, partially obstructing the taxiway behind the Boeing 777, and was not seen by the pushback crew until just before the collision. The accident occurred primarily because the Boeing 777 pushback was not conducted in accordance with the aircraft operator’s normal operating procedures and safe practices. A number of organisational issues were also identified which may have been contributory. Five Safety Recommendations are made
