Faulty 737 Sensor in Lion Air Crash Linked to U.S. Repairer
(Bloomberg) -- A faulty sensor on a Lion Air 737 Max thats been linked to the jetliners deadly crash last October and a harrowing ride the previous day was repaired in a U.S. aircraft maintenance facility before the tragedy, according to investigative documents. (snip)
Documents obtained by Bloomberg show the repair station XTRA Aerospace in Miramar, Florida, had worked on the sensor. It was later installed on the Lion Air plane on October 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. (snip)
"Our thoughts and condolences are with all those who have lost loved ones in the recent 737 MAX 8 accidents," XTRA Aerospace said in a written statement. The company, it said, "is fully committed to supporting any investigations into this matter." (snip)
It's common for licensed repair stations to overhaul older parts so they can be resold, said John Goglia, a former member of the NTSB who earlier worked as an airline mechanic.
Airlines can save money buying used parts and US regulations require that the parts meet legal standards, Goglia said.
