Twelve Chinese families with relatives aboard missing Malaysia Airlines flight 370 have filed a lawsuit in a Beijing court, one day before the deadline for pursuing litigation against the carrier.
The plane disappeared on March 8, 2014 with 239 people - including 153 Chinese citizens - on board while travelling from Kuala Lumpur to Beijing. Under international agreements, families have a two-year window to sue following an air accident.
Speaking outside a transportation court in Beijing, the group's lawyer Zhang Qihuai said on Monday the families are seeking a range of damages but the ultimate goal of the lawsuit is "to find out the cause of the accident and those who are responsible."
Several relatives said they hope to use the case to obtain more information from the airline, which they said has not been forthcoming.
"If we lose this opportunity, it might become even more difficult," said Zou Jingsheng, a professor whose 27-year old son, Ling Annan, was studying in Malaysia and was on the flight.
"We will find out the truth through legal means, and we'll look into the responsibilities that Malaysia Airlines failed to fulfil."
The lawsuit also named Boeing and jet engine manufacturer Rolls-Royce among the defendants. The court will decide if and where to hear the case. Malaysia Airlines did not immediately respond to an email requesting comment about the case.
After two years, the fate of the Boeing 777 remains one of the biggest mysteries in modern aviation. The Australian-led search effort is to continue until June, having already spent more than $A175.47 million looking through a vast area of the Indian Ocean nearly 6.5 kilometres deep.
Investigators believe the plane flew far off course and ran out of fuel in the middle of the southern Indian Ocean. One confirmed piece of wreckage has been recovered, a part of a wing that washed up on an Indian Ocean island last year, and two other possible pieces have been found in the past week.
Victims' kin in China, Malaysia and Britain have urged authorities to continue to search until the plane is found.
Zou's wife, Ling Xiaonan, teared up as she spoke about the case.
"In the two years since the accident, they repeatedly come up with certain news, such as the plane has crashed, then they go on and deny these reports.
"We, the families, can't stand this," she said.
