That is a surprise. I would love to see the failure distribution for those engines. I've seen it for the FA20 because I met and discussed the issue with one of our European friends away from the forum in confidence. The data and conclusion of the internal study fit textbook expectations perfectly. I can imagine one or two outliers for such a great number of total failures, though. Based on the ratio of failures to total in service, leaving it alone would still be a solid bet in any case.
