“Why was a plane with a faulty AoA gauge allowed to fly 3 more times without being properly repaired?”
Red flag and very disconcerting.
It’s one of the reasons the lots of the blame for the first crash was directed to Lion Air’s maintenance and pilot training. If 3 previous flights had correctly dealt with the trim issue, why don’t all the pilots have proficiency in standard 737 skills Another thing was that the pilots in the flight the day before the crash had not written up a maintenance order for the plane. Ethiopian Airlines is another case. It’s a well respected airline and is part of the Star Alliance along with such airlines as United, Lufthansa, Singapore, Air Canada, Air New Zealand, etc.
