Faulty 737 sensor from Lion Air crash linked to US repair shop

A faulty sensor on a Lion Air 737 Max that’s been linked to the jetliner’s deadly crash last October and a harrowing ride the previous day was repaired in a US aircraft maintenance facility before the tragedy, according to investigative documents. Accident investigators in Indonesia, home of Lion Air, and the US have been examining the work that a Florida repair shop previously performed on the so-called angle-of-attack sensor, according to briefing documents prepared for Indonesia’s parliament. Erroneous signals from that sensor triggered the repeated nose-down movements on the Oct. 29 flight that pilots struggled with until the jet plunged into the Java Sea. Documents obtained by Bloomberg show the repair station XTRA Aerospace Inc. in Miramar, Florida, had worked on the sensor. It was later installed on the Lion Air plane on Oct. 28 in Bali, after pilots had reported problems with instruments displaying speed and altitude. There’s no indication the Florida shop did maintenance on the Ethiopian jet’s device. The Indonesian National Transportation Safety Committee is seeking data “from repair station in Florida” where the unit was worked on, the investigative agency said in a briefing to parliament last November and contained in a presentation. Nurcahyo Utomo, lead investigator at the Indonesia NTSC, said the US NTSB was conducting a review of the work performed on the sensor, but hasn’t yet reported back on its findings.<br/>
