South Korean authorities said they would probe the latest incident, which comes a day after 179 people died in the country’s worst civil-aviation disaster.

The plane’s crew discovered a signal warning of a malfunction in the plane’s landing gear after take-off from Seoul, a spokesman for Jeju Air said at a briefing today.

Although the pilot managed to get the gear to work after communicating with the airline’s maintenance centre, the decision was made to return to the airport for a check-up, the spokesman said.

The plane landed safely at 7.20am according to Flightradar24 tracking data.

Passengers were booked on alternative flights.

The Jeju Air spokesman didn’t confirm what model the plane was.

Yonhap News had earlier reported the aircraft was a Boeing Co 737-800, the same type of aircraft involved in yesterday’s crash.
