BEIJING (Reuters) - Boeing Corp. (NYSE: BA) has discovered 2017 faults in its 737max system warning systems due to a software error a year before the deadly Lion Air crash, Boeing said on Sunday.
But the company confirmed that senior officials did not know anything about it before the tragedy of the Indonesian plane.
Boeing said in a statement: "In 2017, several months after the start of the delivery of 737 Max aircraft, Boeing engineers concluded" there is an imbalance in the alarm system. These warnings are intended to alert pilots to some problems.
In the Lion Air incident, which killed 189 people in late October 2018, a specific system was found to have continued to produce false data.
The company pointed out that the audit conducted by engineers did not find that this defect may have a "negative impact on the safety of the aircraft."
The Boeing 737 Max fleet has been shut down since mid-March, following another crash on Ethiopian Airlines on March 10 that killed 157 people in similar circumstances to the Lion Air accident.
