Here’s a link to a Seattle Times article with the most comprehensive summary I’ve read thus far: https://www.seattletimes.com/busines...light-blowout/

Three takeaways that I noted:

- This plug design has been in use since the 737-900ER went into service in 2007. This further reinforces Saab’s point that the root cause is likely in manufacturing, not design.

- Only four (4) bolts secure the plugs in place. There’s little (no?) margin for assembly error.

- The incident aircraft had multiple maintenance write-ups for pressurization problems before the plug blew out. With 20/20 hindsight, there were red flags that weren’t adequately addressed by current maintenance procedures. On the positive side, the airline did restrict the aircraft from extended overwater operations per Extended Range Operations (EROPS) / Extended range Twin engine Operations (ETOPS) standards.
