Boeing issued a safety bulletin to pilots on November 6, instructing crews on how to handle the potential of erroneous data from sensors on its 737 MAX aircraft. The bulletin was issued following the crash of one of the company's planes in Indonesia.

According to news reports, Indonesian National Transportation Safety Committee investigators looking at the crash of Lion Air Flight JT610 have found that one of the plane's "angle of attack" sensors had malfunctioned and provided inaccurate data.

The sensor controls the angle of the airplane's nose relative to oncoming air. If the sensor fails to send correct information, it can confuse both the plane's computer and its pilots, potentially causing an aircraft to take a sudden dive.

The Lion Air plane hit the water 13 minutes after departing Jakarta at 6:20 a.m. on October 30. All 189 people on board were killed.

The "angle of attack" sensors on the plane had been replaced the day before the fatal flight, the Associated Press reported. Additionally, airspeed indicators malfunctioned on the three flights leading up to the fatal crash, as well as during the last flight, Indonesian investigators have said.

The Federal Aviation Administration will require all U.S. airlines that use the 737 MAX aircraft to follow the corrective actions laid out in the bulletin. Around 200 of the planes are in use worldwide.
