FTA: "As per FlightGlobal, the FAA’s proposal is the latest in a series of regulatory actions that have been taken in response to the discovery of iron inclusion in several types of GE Aerospace engines, including the GEnx and CFM International Leap turbofans. The GEnx powers Boeing 787 aircraft, while the Leap powers Boeing 737 Max and Airbus A320neo-family aircraft."

Seems like the title is a bit deceptive. It mentions multiple airliners from both Boeing and Airbus, that are potentially in need of having engine components replaced, due to defects introduced by GE Aerospace.

I was just about to recommend this podcast. I tend to like most things Jake Hanrahan puts out, as they're usually well researched and interesting.
