Not even close to the truth. The NPRM didn’t go far enough. SWA wanted inspections on ALL fan blades over 18 months instead of once in a 12 month period. SWA decided to do ultrasonic inspections on all fan blades in 2017 and exceeded CFM’s recommendations. The new FAA AD issued on all CFM56 engines and CFM directive; SWA meets and exceeds these.
SWA checks every fan blade every 3000 cycles which exceeds any directive from CFM and the FAA.
Sounds like you may have close intel.
What is your take, as to the cause of the blade malfunction ... or cause of engine explosion/failure?
Thanks.

Thanks. I flew on two American 737’s with those engines yesterday. I asked both Captains about it. The first one was just inspected this week and the second was going to the hanger today for the inspection. It wouldn’t of bothered me to get on an SWA plane but I already had tickets on AA. The high bypass jet engine is a marvel of engineering and production quality. Many have thousands and thousands of hours of run time with an incredible track record of reliability.
