A Chennai-bound Air India plane carrying around 120 passengers on board from New Delhi's Indira Gandhi International Airport made an emergency landing in Chennai this afternoon due to a technical problem.

However, all passengers on the Airbus 320 aircraft were deplaned safely on landing of the flight at 1519 hours, sources said.

"The Chennai ATC (Air Traffic Control) received a call from the commander of Air India flight A1-142 at around 1430 hours asking for emergency landing of the flight due to hydraulic failure," the source said.

The flight landed safely at 1519 hours, six minutes ahead of its scheduled time, he said.

An Air India spokesperson in New Delhi said the six-and-a-half-year-old aircraft made the emergency landing due to a hydraulic failure.
