Boeing issues advice to airlines on plane sensor after Lion Air crash

Firm sent the bulletin to airlines that fly its planes; Lion Air jet had issue with attack of angle sensor

Boeing Co. is advising airlines on procedures to deal with false readings from a plane sensor that authorities say malfunctioned on a 737 Max jet that crashed off the Indonesian coast over a week ago.

The operations-manual bulletin was issued Tuesday, Boeing said in a statement posted to Twitter, and tells crew to use existing guidelines when dealing with erroneous inputs from the so-called angle of attack sensor. That sensor is intended to maintain air flow over a plane’s wings but if it malfunctions can lead to an aerodynamic stall — which can cause aircraft to abruptly dive.
