The Air India flight AI2651, operating from Delhi to Bengaluru, was approaching the runway when a Boeing 747, known for its massive size and engine thrust.
The airline said that during the aircraft's final approach to Delhi, the cockpit crew received an alert regarding a fire warning from one of the engines. The alert was later confirmed.
According to a source, the aircraft encountered "wake turbulence" while approaching the runway, following which the pilot decided to carry out a go-around manoeuvre.
