Investigation of missing Malaysia Airlines Flight MH370 took a turn when an unidentified object was discovered washed ashore on southwestern coast of Australia. The object was immediately secured and taken for careful examination by the experts. The update is that the object that was initially thought of possible debris from missing airplane is most likely not from MH370, according to an official as reported by Sydney Morning Herald.

On Wednesday, metal piece with rivets was discovered 10 kilometers east of Augusta, which is near Margaret River, in Western Australia. The material that instigated speculations has been examined by the officials of The Australian Transport Safety Bureau. But chief commissioner of ATSB Martin Dolan confirmed that the metal sheet is not linked to MH370 while speaking to ABC radio on Thursday.

"We've carefully examined detailed photographs that were taken for us by the police and we're satisfied that it's not a lead in the search for MH370," Martin Dolan revealed.

"From our point of view, we're ruling it out," added the officer.

According to the report, the person who discovered the metal sheet on the beach took it to Busselton Regional Airport for examination. The object is described as "alloy type of metal" which is "2.4 meters high and half a meter wide."

This is not the first time when object which appeared to be possible debris from MH370 has been located, but none has proven to be coming from Boeing 777.

Missing Malaysia Airlines flight MH370 disappeared on March 8 with 239 passengers on board while travelling from Kuala Lumpur to Beijing. Search for the missing jet has entered day 46, still there is no clue.

MH370 search mission resumed on Thursday and up to 11 ships and 11 military aircraft will reportedly investigate the search area of 49,567 square kilometers, approximately.

Meanwhile, Australian PM Tony Abbott has assured that Australia will continue the search mission even if there is no debris related to missing Malaysia Airlines flight MH370 is located, according to News.com.au.

"Australia will not rest until we have done everything we humanely can to get to the bottom of this mystery," PM Tony Abbott said.

Australian PM vowed that they won't "abandon the families of six Australian citizens that were on the plane." He also assured that they "won't let down the families of the 239 people on the plane by lightly surrendering while there is reasonable hope of finding something."
