Boeing limited the involvement of its own pilots in the last phases of the development of 737 MAX flight control system, MCAS, linked to earlier deadly jet crashes, The Wall Street Journal reported on Friday citing its sources.
This reportedly led to the failure to supply the pilots who contributed to the jet's development with briefings outlining the specifics of the control system.
It is noteworthy that previously the company provided a larger role to pilots and used to seek input from them.
The US aircraft producer started to investigate its jets after two Boeing 737 MAX aircraft crashed over the past six months — one in Indonesia in October 2018 and another in Ethiopia in March. In the wake of the latest crash, aviation authorities and carriers around the world have either grounded all 737 MAX series aircraft or closed their airspace to them.
The investigations into the incidents are underway but experts believe that the Maneuvering Characteristics Augmentation System could be responsible for the crashes.
