Earlier this week, Malaysia Airlines confirmed that Flight MH2664 from Kuala Lumpur to Tawau on April 3 returned to KLIA due to “technical issues'”, with passengers reporting that the plane had suddenly “dived” before returning to the airport.

A Bernama report has also said a passenger “floated” out of her seat when the incident happened because her seat belt was unfastened as the sign was turned off at that time.

“I call on the transport minister to make a public commitment to an independent investigation and for any results to be announced in the near future,” said Loke in a statement.

Stressing that civil aviation safety is a crucial aspect of the national transportation system, the DAP secretary-general said that announcing the results of the investigation would help boost the public’s confidence.

On Tuesday, the Civil Aviation Authority of Malaysia (CAAM) said it would be reviewing Malaysia Airlines’ internal flight data monitoring system that monitors and records all flight data profiles.

Three of the passengers have refused to accept Malaysia Airlines’ account of the incident that the flight turned back due to technical issues and that the technical problems “were compounded by bad weather en route”.

The passengers, Abdul Rahim Awang Nong, 48, Halimah Nasoha, 39, and Chui Ka Wai, 48, lodged separate police reports on the incident yesterday and also want the report of the investigation to be made public.

They claim there was fine weather at the time of the incident.
