PETALING JAYA - AirAsia X is conducting an investigation into Flight D7237 that made an emergency return to Perth Airport due to a "technical issue".
"We are currently conducting an investigation into the cause of the incident together with our engine manufacturer Rolls-Royce. We are also cooperating fully with the local aviation authorities," AirAsia X said in a statement on Monday.
Passengers aboard the flight bound for Kuala Lumpur from Perth, Australia on Sunday heard a small explosion on the left wing.
According to reports, the aircraft was shaking like a "washing machine" during the two-hour flight back to the airport.
