JAKARTA—A crucial sensor was replaced on a Lion Air jet the day before it plunged into the Java Sea, and that sensor replacement may have exacerbated other problems with the plane, Indonesian investigators said Wednesday. That sensor, known as the “angle of attack” sensor, keeps track of the angle of the aircraft nose to help prevent the plane from stalling and diving. Investigators examine engine parts from the ill-fated Lion Air flight JT 610 at a port in Jakarta on November 7, 2018, after they were recovered from the bottom of the Java sea. “We will.” Boeing, which manufactured the Lion Air plane, issues safety-related bulletins, and had previously circulated instructions about what flight crews should do if sensors fail. Lion Air is one of Indonesia’s youngest airlines but has grown rapidly, flying to dozens of domestic and international destinations.
