The NTSB has released the FINAL REPORT on the uncontained engine failure in flight suffered by SWA Boeing 737-7H4 N772SW (CN 27880, LN 601) on April 17th, 2018. The failure resulted in the rapid decompression of the cabin, and the unfortunate fatality of a passenger. Lots of great info and images in the article.

"On Dec 12th 2019 the NTSB released their final report concluding the probable cause of the accident was:

The National Transportation Safety Board determines that the probable cause of this accident was a low-cycle fatigue crack in the dovetail of fan blade No. 13, which resulted in the fan blade separating in flight and impacting the engine fan case at a location that was critical to the structural integrity and performance of the fan cowl structure. This impact led to the in-flight separation of fan cowl components, including the inboard fan cowl aft latch keeper, which struck the fuselage near a cabin window and caused the window to depart from the airplane, the cabin to rapidly depressurize, and the passenger fatality."
