All Boeing 737 NG To Have Redesigned Engine Nacelles Following Deadly Southwest Incident (msn.com)
The project was launched in 2019, following the conclusion of the investigation into a 2018 Southwest Airlines accident that left one passenger dead and eight injured.

A similar, non-fatal accident was also recorded by Southwest Airlines two years prior when debris from the engine cowl punctured part of the fuselage.
