The US Federal Aviation Administration (FAA) warned airlines last week that erroneous inputs from the system's sensors could lead the jet to automatically pitch its nose down even when autopilot is turned off, making it hard for pilots to control.
Even though this was not covered in the manual book provided to pilots, Boeing said last week, after releasing a bulletin that they will continue to investigate and understand all aspects of the incident.
