The AS1282 incident in 2024 won't occur again with this new door plug. Here's how, and why was this change necessary?

Boeing and the FAA have improved training and processes since 2024 incident, according to the NTSB, but board officials said both organizations need to better identify manufacturing risks.

The National Transportation Safety Board investigation over the past 17 months found that four bolts securing what is known as the door plug panel were removed and never replaced during a repair as the Boeing 737 Max 9 aircraft that lost the panel after takeoff from Portland International Airport was being assembled.
