KUALA LUMPUR, June 29 — Datuk Seri Dr Liow Tiong Lai's maiden task as Transport Minister should be to form an independent body to investigate the mystery surrounding MH370, which has been missing for almost four months now, PKR's Nurul Izzah Anwar said today.

She said the investigation panel should consist of air crash experts from around the world, pointing out that Malaysian officials have yet to come up with any plausible theory or explanation with regards to the missing Malaysia Airlines flight.

“One of the main responsibilities of the minister is to form an independent investigative body for the MH370 incident,” she said in a statement here.

Liow must also reveal details of the audit done by the International Civil Aviation Organization (ICAO) on the newly-built KLIA2 terminal and the Subang Airport, the Lembah Pantai MP said, pointing out that the Subang Airport had experienced a flight radar failure back in September 2012.

A thorough disclosure of the ICAO's audit report on both airports and their flight radar systems will allow “improvements” to be made to avoid another tragedy like MH370 from taking place again, Nurul Izzah added.

“The former acting transport minister Datuk Seri Hishammuddin Hussein has stated that the ICAO will conduct an audit on the safety of the KLIA2.

“The scope of this audit is still unknown. Has this been completed? If so, I ask that the minister reveal the contents of the report immediately,” she said.

Beijing-bound Flight MH370 vanished from civilian radar on March 8 slightly more than an hour after departing from the Kuala Lumpur International Airport.

Malaysian authorities said radar data indicated that the plane with 239 people on board had diverted from its intended path and headed towards the southern Indian Ocean, which is where the Boeing 777 is believed to have ended its flight.

Putrajaya and Malaysia Airlines have been heavily criticised domestically and abroad for  handling of the disaster, with critics pointing to the government's slow response and lack of coordination in the search and rescue operations.

The plane's disappearance has been touted as civil aviation's greatest mystery.
