The inspections are necessary to identify and replace parts suspected of causing inaccurate AoA indications. The requirement comes from a Feb. 9 airworthiness directive issued by the European Aviation Safety Agency (EASA) after final assembly line testing revealed that AoA data from two different aircraft were incorrect. Flight data analysis confirmed the inaccuracies.
