A system malfunction forced the pilots of an AirAsia X flight from Kuala Lumpur to Jeddah to abort the flight and return to Malaysia today, the AirAsia Group's CEO said.
The incident sparked fresh questions on social media about the Malaysian airline's safety record as it struggles in the aftermath of the loss of Flight QZ8501 in late December with 162 people on board.
"One auto-thrust not functioning properly. Actually okay to fly but we just returning it to base," Tony Fernandes told AFP in a text message, calling it a "minor issue."
He confirmed the plane - operated by the long-haul arm of the AirAsia Group of carriers, AirAsia X - landed safely at Kuala Lumpur's international airport today afternoon.
Flight-tracking websites indicated AirAsia X flight D7172 flew several wide circles over the Strait of Malacca to burn off fuel.
Fernandes called the manouevre a "routine" precaution as the plane was heavily laden with fuel that normally would have been used up during the several-hour flight to the Saudi Arabian city.
"Just burning off fuel as has lots of fuel as was going to Jeddah," he said, adding that the plane would be changed and the flight would continue onward.
"What is happening with Malaysia and airplanes? This is really, really scary," posted one Twitter user.
Flight QZ8501 went down in stormy weather on December 28 in the Java Sea during what was supposed to be a short trip from the Indonesian city of Surabaya to Singapore.
Malaysia Airlines flight MH370 disappeared last March after inexplicably diverting from its Kuala Lumpur-Beijing course. The airliner, carrying 239 people, is believed to have crashed in the Indian Ocean, but no trace has been found.
MH17 went down last July in rebellion-torn eastern Ukraine - believed hit by a surface-to-air missile - killing all 298 aboard. Malaysia Airlines had previously had a solid safety record.
