Title: AoA sensor errors on Lion Air flights JT043 and JT610
It has now been confirmed that the replacement AoA sensor that had a 22° offset on Lion Air flights JT043 and JT610 was a reworked sensor. On 28 November 2018, investigator Nurcahyo Utomo of the Indonesian National Transportation Safety Commission (KNKT) told reporters that the AoA unit that was installed in the ill-fated airplane had previously been fixed by Boeing in Florida. He stated that the team will also visit the Florida maintenance facility to check the procedure that was used to fix the AoA.
