On March 26, a Southwest crew was ferrying a 737 Max 8, without passengers, from Orlando to Victorville for long-term storage. Shortly after takeoff, pilots experienced what was described at the time as a "performance issue" with the No. 2 engine, leading to an engine overheat. The plane returned to Orlando and landed safely and the incident is still being investigated.
Southwest Chief Operating Officer Michael G. Van de Ven said, "The working theory on that particular airplane was that there was coking around the fuel nozzles and it created a variance in the hotspots and cold-spots in the engine."
Southwest CEO Gary Kelly told an analyst he believes this is a "break-in issue" with the new CFM engines.
...Coking, a byproduct of combustion, essentially involves a tar-like gunk that can build up. According to the FAA, coking can restrict fuel flow to some nozzles and causes greater amounts of fuel to flow into nozzles empty of the tar, thus creating a dangerous and uneven heating in the engine.
Those initial findings prompted Southwest Airlines to inspect 12 engines from its fleet of 34 Boeing 737 Max jets parked in Victorville, California since the worldwide grounding.

Boeing doesn’t make the engines, and the customer picks which engine they want.
You seem to be on a campaign against Boeing.
Under its current leadership, you betcha. I fly a lot, and want clean house.
The airlines will be dealing with the engine companies on this matter as well.
As a sidenote though, it’s worth noting Boeing decides where to *place* the engine though, thus affecting the relationship of the engine to the mechanics and aerodynamics of the rest of the plane.
MIT Expert Highlights ‘Divergent Condition’ Caused By 737 MAX Engine Placement
"and the customer picks which engine they want."
That's a new one on me. Which I doubt.
Today’s engines are too complicated for me to really know, but it sounds more like a maintenance issue than deficiency in the engine itself, no?
I used to think airline deregulation was a good thing, but it seems that too many airlines push the envelop with it comes to maintenance.
Unrelated to this article, but important, is that affirmative action and lowering standards for ATC is insane.
All good points Paulie, and to be honest...even before the Boeing MAX fiasco, I was getting ‘icky’ feelings about the general business turns certain airlines (like Southwest’s CEO) were taking and feeling like crises were mounting.
CFM is used in the following Aircraft: Airbus A320neo family,
Boeing 737 MAX, Comac C919.
The first part of your statement is true, but the second part is not. Only the CFM LEAP engine is offered on the MAX. No choice.
With the competing Airbus A320 NEW, and with other Boeing aircraft such as the 747 and 787, you do have a choice of engines. But not with the 737 MAX.
I’ve heard of occasional issues with the LEAP engines on both the 737 MAX and A320neo planes. I believe they have been resolved several months ago (I haven’t heard of issues with the LEAP-1A engines on the A320neo Family planes).
Oops, typo. A320 NEO, not NEW.
Thank you for the info!
You’re many times more likely to die in a car accident.
Based on that, I take it to read that the Max has a specific engine which is what makes it a Max.
That statistic makes sense given all the air flights daily. On the other hand, when multiple aircraft of a specific type crash within a short amount of time, those statistics go out the window if you get on one of those types of planes.

Not true.
Over 100 people die in car accidents every day in the United States. Globally, the number is much higher.
However, you were a lot more likely to die in a 737 MAX in the third world with their lax pilot standards, than in a 737 MAX based in the United States.
Okay. If you say so. Boeing has admitted they released a defective product that they have to fix so I’m not sure why you think they are lying but personally I believe them.
Boeing said they released a safe product, and they are making it safer.
