Panel to review approval of Boeing 737 Max flight controls







DETROIT – A global team of experts next week will begin reviewing how the Boeing 737 Max's flight control system was approved by the US Federal Aviation Administration.

The FAA says experts from nine international civil aviation authorities have confirmed participation in a Technical review promised by the agency

Former National Transportation Safety Board Chairman Chris Hart will lead the group, which will also have experts from the FAA and NASA. They'll look at the plane's automated system including the way it interacts with pilots. The group will meet Tuesday and is expected to finish in 90 days.

The Boeing jetliner has been grounded around the world since mid-March after two crashes killed 346 people. Investigators are focusing on anti-stall software that pushes the plans down based on erroneous sensor readings.

In a statement Friday, the FAA said aviation authorities from Australia, Brazil, Canada, China, the European Union, Japan, Indonesia, Singapore, and the United Arab Emirates have agreed to help with the work, called a Joint Authorities Technical Review. The group will evaluate the automated flight control design and determine whether it complies with regulations. It will also decide if changes need to be made in the FAA's approval process. In October, the crash crashed into the coast of Indonesia and a March crash in Ethiopia, a faulty sensor reading triggered by MCAS and pushed the plane's nose down, and pilots, unable to recover.

even know about MCAS until after the October crash. They then received computer training that described the system and how to respond when something goes wrong with it. Muilenburg said test pilots flew 120 flights totaling 203 hours with the new software. The company is expected to conduct a crucial certification flight with an FAA test pilot on board, possibly next week.

'' We are making steady progress towards certification 'and returning the Max to service, Muilenburg said in a video posted by Boeing.

Muilenburg also said he went on a test flight that day, Wednesday, and saw the software update 'operating as designed across a range of flight conditions.' '

The video was filmed at Boeing Field in Seattle.
