Boeing has issued a bulletin to airlines on the subject of erroneous data from angle-of-attack sensors on its Boeing 737 Max aircraft.
The bulletin comes in response to the initial investigations into the Lion Air 737 Max crash in Indonesia last week that killed 189 people.
Boeing says the bulletin, which was released yesterday, directs operators to existing flight crew procedures to address circumstances involving erroneous angle-of-attack sensor information being given.
The Seattle-based air-framer adds that issuing bulletins such as this one is a normal process as the investigation into the Lion Air crash continues.
In a statement Boeing said: “Boeing continues to co-operate fully and provide technical assistance at the request and under the direction of government authorities investigating the accident”.
Indonesia’s National Transportation Safety Committee (NTSC) has already indicated that it believes the Lion Flight received incorrect data from its angle-of-attack sensors and this could have also occurred on the four previous flights before the accident.
Lion Air Flight JT610 crashed into the sea shortly after taking off from Jakarta’s Soekarno-Hatta International airport on a flight to Pangkal Pinang.
The Boeing 737 Max has received nearly 5000 orders and is already in service with several European airlines including Norwegian and the TUI Group.
