What the record shows
The MAX 9 has zero fatal accidents in 1.8M flights. The MAX 8 had two fatal crashes (2018-19) caused by a flawed MCAS system, that system was completely redesigned before the MAX 9 entered wide service. A 2024 door plug event (zero fatalities) prompted fleet-wide inspections and strengthened Boeing quality oversight. Today's MAX 9 flies with all post-crisis fixes, enhanced FAA scrutiny, and mandatory pilot training on the redesigned systems.
Engine programme: CFM LEAP-1B, no systemic engine ADs. The MAX's 2018-19 accidents were flight-control (MCAS), not engine-related.
