Software Fix Addresses Cabin Smoke Concern On Boeing 737 Max

GE Aerospace is working to introduce a software update for the Boeing 737 Max’s CFM International Leap-1B turbofan to address cabin-smoke risks arising during engine failures. The update, which is currently in the certification process, is expected to enter service this year. The software fix was developed in response to two Southwest Airlines 737 Max flights in 2025, where a large bird was sucked into a Leap-1B, causing fan separation and potential smoke in the cabin. According to GE vice-president Carlos Perez, the update is intended to minimize smoke by closing a valve more quickly. This development was first reported by FlightGlobal.
