Boeing failed to warn the airline industry about a potentially dangerous feature in its a new flight-control system that is suspected of playing a role in the fatal Lion Air crash in Indonesia last month, The Wall Street Journal reported late on Monday.
That aircraft feature is the automated stall-prevention system found on Boeing 737 MAX 8 and MAX 9 models, the Journal reported, citing industry sources including safety experts, aviation regulators and airline pilots.
Boeing didn't immediately reply to CNBC's request for comment. The company told the Journal that it is "taking every measure to fully understand all aspects of this incident, working closely with the investigating team and all regulatory authorities involved."
The system in question is designed to help pilots avoid raising a plane's nose too high, which can cause it to stall, according to the report. The potential fault in the system is that it can push the plane's nose down "unexpectedly and so strongly" that pilots can't pull it back up even when flying manually, the report said. It added that when that happens, the plane could dive or crash.
Boeing revealed the possible fault in a bulletin to airlines about a week after the Lion Air crash, the report indicated.
Lion Air's new Boeing 737 MAX 8 crashed into the Java Sea last month shortly after taking off from Jakarta's Soekarno-Hatta airport. The plane was carrying 189 people, including crew.
