Boeing crash clues spark questions over why plane cleared to fly

Investigators are slowly piecing together clues of how Indonesia’s worst air disaster in two decades transpired, raising questions over how a near brand-new Boeing jet that had recurring instrument failures was cleared for its ill-fated flight. The Lion Air Max 8 plane’s angle-of-attack sensor was replaced the day before the Oct 29 crash after erroneous readings on a previous trip, the Indonesia NTSC said Wednesday. Faulty airspeed readings plagued the jet on its last 4 flights before it plunged into the Java Sea. The revelations spurred Boeing to alert operators of the 737 Max aircraft worldwide that the airflow sensor can provide false readings in certain circumstances. That warning and the investigation team’s statement suggest the pilots on JT610 may have been battling with the aircraft as its computers commanded a dive. <br/>
