Officials from the European Union Aviation Safety Agency have told the FAA that the Europeans need to make their own findings on the safety of Boeing's proposed fixes for the aircraft, a USA official said.
Relatives of Canadians killed in the Ethiopian Airlines flight crash also filed a lawsuit against Boeing and Rosemount Aerospace Inc. which designed the sensors used in the 737 MAX 8.
On Wednesday, Air China Ltd and China Southern Airlines Co Ltd told Reuters the pair have added their voices to a compensation request from China Eastern Airlines Corp Ltd announced a day earlier.
According to public information, there were 96 Boeing 737 Max aircraft in use and Chinese companies had ordered 180 more units as of January.
Aviation regulators from 33 countries, including the UK, Europe and China, are meeting in Texas.
A Boeing 737 Max 7 lands at Boeing Field in Seattle after a test flight to evaluate the MCAS software fix.
"It's a great opportunity for the FAA to work on its communications and to get input from overseas regulators about their concerns with the 737 MAX as well as the certification process, which has been pretty much the world standard to this point", James Hall, a former chairman of the National Transportation Safety Board, told China Daily. Among the questions is whether simulators should be required before the planes are allowed back in the air, which would be more expensive and time consuming yet also more immersive, or whether the needed training could be done on a tablet computer.
New details emerge on Huawei’s potential plans to go forward without Google
Still, he stressed that would only happen if the company were completely stopped from using Google's and Microsoft's software. It means you can probably abandon any hope of seeing Android Q on any Huawei devices.
The 737 MAX was grounded following the March 10 Ethiopian Airlines crash, which together with an Indonesian Lion Air crash in October claimed 346 lives and were both blamed on faulty technology in the aircraft.
The aviation world's eyes are on Fort Worth, where USA and global regulators meet behind closed doors Thursday to discuss if the Boeing 737 Max is safe to return to the skies.
"Data is fine but it's something that's right before your eyes", he said, noting that non-US regulators reacted with appropriate urgency. "It's a completely safe aircraft", he said in an interview published Wednesday.
Shanghai-based China Eastern has grounded its 14 MAX planes while the U.S. aviation giant addresses the safety risks, Xinhua reported.
But he said the agency is still waiting for Boeing to formally submit the software upgrade for approval, and emphasised the FAA has not decided on the revised training requirements, including whether to require simulator training.
The anti-stall system on the MAX models has been blamed in large part for the Ethiopian Airlines tragedy.
