The CFM56 family of engines frequently receives praise for its long on-wing time, which keeps extending with the introduction of new models. At MRO conference sessions or during interviews about engine reliability, the venerable powerplant often comes up.
So should I be surprised by CFM's news today that a CFM56-7B powering a TUIfly Boeing 737-800 logged more than 50,000 hours without a shop visit? 50,000. CFM says "this record is equivalent to driving the same car for 16 years with nothing more than oil changes and tune ups, or flying 20 million miles with no engine removal."
At this point, you're probably wondering why the engine couldn't keep flying. TUIfly and CFM say the powerplant was performing well and showing good EGT margins, but they had to remove it to replace life-limited parts.
