In the wake of the Lion Air Crash in Indonesia last month, the Federal Aviation Administration (FAA) and Boeing Co. are deciding whether to issue a software fix on the 737 Max, after the software caused the plane to aggressively dive without the pilot’s commands, as stated in a Reuters report.
Boeing and the FAA continue to evaluate the need for upgrades to the software or are planning to change the design of the aircraft.
Indonesian investigators said more training was needed for 737 Max pilots after finding out that the scenario was not included in the flight manual.
Investigators first stated that a faulty sensor caused the plane to stall, but now it appears that Boeing didn’t adequately inform pilots how the new feature worked in training and in training manuals.
Information recovered from the jet’s data recorder prompted the FAA to issue an operation warning on November the 7th ordering airlines to incorporate information about the plane and its features into the manual.
They warned pilots that computers on the 737 Max could force the plane to dive, making it difficult for pilots to control.
Pilots could have stopped the plane from acting uncontrollably by pressing two buttons.
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.
It has been reported that pilots on a previous plane experienced a similar sensor problem.
Investigators are planning to prepare a preliminary report on the crash on November 28 or November 27.
