Boeing yesterday issued an operations manual bulletin (OMB) to 737 Max 8 operators about air data sensors 8 after an investigation into the crash of the Lion Air flight JT610 in Indonesia which killed 189 passengers and crew.

The US aircraft manufacturer said the Indonesian National Transportation Safety Committee (NTSC) has indicated the Lion Air flight JT610 experienced erroneous input from one of its AOA (angle of attack) sensors and media reports claim the NTSC believes it was operating with airspeed indicator faults on its last four flights.

AOA information is critical to avoiding the onset of stall conditions.

Boeing said: “On November 6, 2018, Boeing issued an Operations Manual Bulletin (OMB) directing operators to existing flight crew procedures to address circumstances where there is erroneous input from an AOA sensor.

“The investigation into Lion Air flight 610 is ongoing and Boeing continues to cooperate fully and provide technical assistance at the request and under the direction of government authorities investigating the accident.

“Boeing is providing support and technical assistance to the Indonesian National Transportation Safety Committee and other government authorities responsible for the investigation into Lion Air flight JT610.”

The Lion Air 737 Max 8 crashed into the sea on Monday 29 October shortly after taking off from Jakarta Soekarno–Hatta International Airport, and was heading for Pangkal Pinang in the Bangka Belitung Islands, killing all 189 on board.

As of 6 November, 186 body bags containing human remains have been recovered from the search area.
