BEIJING: US accident investigators arrived in China on Saturday to help authorities look for clues into what caused last month’s crash of a Boeing jetliner with 132 people aboard.
The seven-member team from the National Transportation Safety Board will participate in the Civil Aviation Administration of China’s investigation of the March 21 crash of a China Eastern Airlines Boeing 737-800.
As part of that assistance, the plane’s cockpit voice recorder is being downloaded and analyzed at a U.S. lab in Washington, federal officials said Friday.
Investigators hope the recording will explain why the plane went into a nosedive from about 8,800 meters (29,000 feet) over a mountainous region in southeastern China.
Chinese officials have said that air traffic controllers were unable to get a response from the pilots while the plane was descending.
The cockpit voice recorder would pick up voices and other sounds from microphones worn by the pilots and another stationed over their heads.
The NTSB said its investigators will limit contact with people outside the investigation so that they can start their work immediately without going through a quarantine period.
The impact caused by the crash in China created a 20-meter- (65-foot-) deep crater, set off a fire in the surrounding forest and smashed the plane into small parts scattered over a wide area, some of them buried underground.
The 737-800 has an excellent safety record and the Chinese airline industry has had relatively few mishaps in recent years.
Before last month’s accident, the last fatal crash of a Chinese airliner occurred in August 2010, when an Embraer ERJ 190-100 operated by Henan Airlines hit the ground short of the runway in the northeastern city of Yichun and caught fire, killing 44 people. Investigators blamed pilot error.
