Boeing issued a special bulletin on Wednesday addressing a sensor problem flagged by Indonesian safety officials investigating the crash of a Lion Air 737 that killed 189 people last week.
The planemaker said local aviation officials believed pilots may have been given wrong information by the plane’s automated systems before the fatal crash.
“The Indonesian National Transportation Safety Committee has indicated that Lion Air flight 610 experienced erroneous input from one of its AOA (Angle of Attack) sensors,” the warning said.
“Boeing issued an Operations Manual Bulletin directing operators to existing flight crew procedures to address circumstances where there is erroneous input from an AOA sensor.”
