Safety experts recommended Wednesday that the engines on Boeing's troubled 737 Max airplanes be modified quickly to prevent smoke from filling the cockpit or cabin after a safety feature is activated following a bird strike.
The problem detailed by the National Transportation Safety Board emerged after two bird strikes involving Southwest Airlines planes in 2023 — one in Havana, Cuba, and another in New Orleans. The Federal Aviation Administration and Boeing already warned airlines and pilots about the problem and the engine maker has been working on a fix.
The NTSB said that the engines CFM International makes for the Boeing plane can inadvertently release oil into the hot engine when the safety feature, called a load reduction device, is activated after a bird strike or similar engine issue. The resulting smoke feeds directly into either the cockpit or passenger cabin depending on which engine was struck.
Similar engine models with the same safety feature are also used on Airbus A320neo planes and C919 planes made by the Commercial Aircraft Corporation of China. The NTSB urged European and Chinese aviation safety regulators to evaluate those engine models to determine if they could also be susceptible to the smoke problem.
Safety device solved one problem but created another
The new safety device that CFM added to its engines solved one problem by limiting damage when an engine starts to come apart, but created a new problem by releasing the oil that burns and generates smoke.

I don’t fly any more (I used to back in the day for my job) but there is no way, period, end of statement, that I would fly a 737 Max..

If it’s Boeing, I ain’t going!
An unsafe safety feature? Swell!
CFM International is a Franco-American aircraft engine manufacturer. The company is a joint venture between GE Aerospace and Safran Aircraft Engines (formerly known as Snecma) and is headquartered in Cincinnati, Ohio. It was founded in 1974 to build and support the CFM56 series of turbofan engines. CFM is the world’s largest commercial aircraft engine manufacturer, with a 39% market share as of 2020.[1] It has delivered more than 37,500 of its engines to more than 570 operators. The name CFM is derived from the two parent companies’ commercial engine designations: GE’s CF series and Snecma’s M series.
oops
Who put that stovepipe directly into the cabin anyway?
This STUPID DESIGN is easily solved by using the APU to feed air into both the Cockpit and Cabin.
Has anyone ever heard of an APU being damaged by a bird strike ???
It still baffles Me as to why both engines are not capable of running the electrical system and other control systems.
