Part 4/11:
Before the ill-fated flight on October 29, 2018, ongoing mechanical issues plagued one of Lion Air's 737 Max aircraft. Multiple alarms and faults had been recorded, particularly related to the aircraft's angle of attack (AoA) sensor. Nevertheless, this aircraft was cleared for service, despite technicians' inability to definitively clear persistent faults stemming from the damaged sensor. This situation demonstrated a concerning trend: a culture of reassuring complacency overshadowing critical safety checks.
