KUALA LUMPUR, Aug 2 ― A group of pilots are urging the Australian government to keep up its search for Flight MH370's aircraft following the surfacing of new evidence that indicate a larger search zone.

David Booth, the president of the Australian Federation of Air Pilot which represents over 4,500 airline and commercial pilots, said the idea that the Australian government is "not going to search for the airplane to finality is a serious precedent in all aviation”.

"This is critical to me as an aviator … the airplane’s missing, we need to find the airplane.

"Presumably the government doesn’t want to put ― another US$200 million into a search, as well as embarrass the Malaysians,” he was quoted saying to The Australian.

The Australian, Malaysian and Chinese governments have reportedly agreed to suspend the search for the MH370 aircraft when the targeted search zone of 120,000 square kilometres is fully combed unless there is new credible evidence.

Booth said his union decided to make its call following claims last weekend that a flaperon ― a portion of a wing - from the MH370 flight backed theories of a rogue pilot bringing down the aircraft in a controlled ditch or glide.

This new evidence should push the Australian government to pursue the hunt for the MH370 aircraft's final location in a zone that matches the rogue pilot scenario, he said.

"Obviously you can’t spend limitless amounts of money to that end, but where there are reasonable theories pointing to where the aircraft could be, they should be pursued,” Booth was quoted saying.

The Australian said Australian Transport Safety Bureau spokesman Tim Dawson and a spokesman for Transport Minister Darren Chester declined to say if the Australian government knew whether the claims regarding the flaperon are accurate.

The Malaysia Airlines-owned Boeing 777-200ER jet, which was carrying 239 people on board from Kuala Lumpur to Beijing, disappeared on March 8, 2014.

The underwater search in the southern Indian Ocean for the plane has cost almost A$180 million (RM549.54 million).
