Recap from 2016: The investigation into the failure on Southwest #WN3472 showed signs of a fatigue crack on one of the titanium alloy fan blades at the front of the engine. Destroyed the cowling/nacelle & sent debris into the airframe. #WN1380 bit.ly/2H6qDBN

Industry officials are concerned the Boeing 737's engine nacelle design constitutes an even larger challenge than just ensuring that all vulnerable CFM56 fan blades are inspected, found and replaced. There are more than 12,000 in service. bit.ly/2qK5X7u #WN1380 #WN3472

Alaska Airlines said it is accelerating inspections of its 737 engines. Been doing inspections since 2016 and #WN3472. "We have been working aggressively to complete inspections sooner than recommended. As of today, we have engines on 25 aircraft left to inspect."

Following #SouthwestAirlines #WN1380 accident (and knowing what happened to flight #WN3472), wouldn't it be a good idea to ground all CFM-powered Southwest B737-700 ?


Thread: #WN3472 was a very similar incident in 2016 where the same CFM-56 engine threw a fan blade and the debris was not contained. In that case, it struck the fuselage, not a window. There is a pending airworthiness directive that would require inspections of CFM-56 fan blades.

As a matter of background, after #WN3472 the FAA proposed an airworthiness directive to perform eddy current inspections on a certain population of CFM56-7B fan blades. Specifically on engines with 15,000 cycles or less since their last shop visit. #WN1380



That is an engine missing one of its front fan blades. Nearly identical to #WN3472 in 2016.

#WN1380, like thousands of 737s produced since 1995, uses a @CFM_engines CFM56-7 engine. (CFM is a partnership between @SAFRAN's @SafranEngines and @generalelectric's @GEAviation.) This is a longstanding and reliable engine, though there are similarities with #WN3472 in 2016.


As you can see, the engine cowling is missing from #WN1380, much as it was from #WN3472 in August 2016. Engines are designed and tested so that, when they fail, the failure is "contained" (not "uncontained") within the engine structure.
