I don't have the statistical data available to disagree, Tdracer. I also agree with you that engine cowls do seem to be going missing rather often - perhaps the material selection of modern engine cowls is part of that. Back in the early days of turbojets, we had hulking hunks of aluminum around them.
That is not to say a well designed inner ring of plastic is not what the doctor ordered regarding fan blade containment, but statistics seem to agree with your observation regarding the cowling itself.
Who is the engine manufacturer? GE?
The majority of the core is manufactured by the American GE, with the French company Safran (formerly SNECMA) manufacturing and designing the fan, some ancillary bits, the nacelle, and the LP turbine and compressor assemblies. It has been among the most reliable turbofans ever placed into commercial service.
