Pilots of an Air India flight operating from Delhi to Indore on Sunday declared "mayday" which was later downgraded to a “pan pan” call before landing back at the originating airport after reporting a fire indication in the right engine, sources said.

According to the airline, the flight returned to Delhi after the cockpit crew received a fire indication for the right engine of the aircraft and the landing was done safely following standard procedure.
“Flight AI2913, operating from Delhi to Indore on 31 August, air-returned to Delhi shortly after take-off, as the cockpit crew received a fire indication for the right engine. Following standard procedure, the cockpit crew elected to shut down the engine and returned to Delhi where the flight landed safely. The crew had initially made a MAYDAY call to the air traffic control, but later downgraded it to PAN-PAN to indicate urgency rather than an emergency. We confirm that the flight did not make an emergency landing at Delhi. At Air India, the safety of passengers and crew are our top priority,” said the Air India spokesperson.
The Air India aircraft – operated with an A320 neo aircraft under callsign AI2913 – landed back in Delhi on Sunday after being airborne for over 30 minutes as the pilot received a "fire indication" in the right engine of the aircraft.
