CFM Fixes Leap Turbine Shroud Coatings
CFM began delivering new Leap engines with the permanent CMC environmental-barrier coating fix in June.
Turkish carrier Pegasus Airlines was the first operator to put the LEAP engine into commercial service, on an A320neo in the summer of 2016.

As of June, all new-production CFM International Leap-1A and Leap-1B engines delivered to Airbus and Boeing incorporate the permanent ceramic matrix composite (CMC) fix developed by CFM International. The fix mitigates an environmental barrier coating degradation issue that affected the CMC shroud surrounding the first high-pressure turbine stage of in-service examples, according to Gaël Méheust, president and CEO of the CFM joint venture.
