Nobody should expect perfections (no failures) but of course the corrective action were expected to significantly lower the risk of no duals
Post 737max debacle I don’t think it’s premature. I could actually see a reduction in hours for both versions if the failure is the same. Time on the failed engine will of course be a consideration.
