AirAsia X Berhad engineers are taking precautionary steps to check the aircraft forced to return to Perth after it started shaking violently on a trip to Kuala Lumpur.
Flight D7237 departed just before 7am WST (11am NZT) on Sunday for Kuala Lumpur with 359 people on board and was about 90 minutes into the flight when the pilot identified what AirAsia says was a technical issue.
The budget airline was already been under increased scrutiny from the air safety watchdogs over previous incidents and is facing another investigation after a turbine blade in the plane's left engine allegedly sheared off less than two hours into a flight.
The A330 flight PER-KUL landed safely at Perth International Airport a short time ago.
One person posted a video of the plane shaking on Instagram, where the user @maesaya wrote, "I thought I might die".
He said the pilot asked passengers to pray twice. No one was hurt during the incident.
It was a terrifying experience for hundreds of passengers aboard an AirAsia flight.
Dave Parry told ABC that passengers were told to brace for impact on landing.
"I feel fine but a lot of people I've spoken with are really shaken and quite apprehensive about the flight", Stevens said. The pilot shook hands with all of the passengers after the flight was over. "The plane erupted with applause once we landed".
"Passengers were attended to by our ground staff upon landing and were provided with all necessary assistance", AirAsia said in a statement.
