The last few incidents with the MAX series has me on edge with them. I fly planes myself (GA) and am an aviation geek. It's only 3 incidents but it seems like they rushed the MAX out too quickly to compete with Airbus. I could be really wrong.
The MAX 8 series was the one where they had additional software to correct the climb and this caused two accidents of total loss in passenger planes Lion Air Flight 610 and Ethiopians Flight 302.
Between March 2017 and March 2019, the global fleet of 387 aircraft operated 500,000 flights and experienced two fatal crashes, having a fatal accident rate of four accidents per million flights, whereas the previous Boeing 737 generations averaged 0.2 fatal accidents per million flights.
Then we have the MAX 9 that had a door blow off because of a missing door plug. Thankfully, no deaths and only minor injuries.
