Most of those were not because of failures, but faster wear of some components that could not be done with the engine on the wing. That is of course not sustainable...
Not just at NK. Supposedly the fix for that is available, but it takes time to produce the parts and swap them out. Apparently a lot of the production of new parts is going to new engines for the factory backlog, the engines in service are having to share availability with new production. Also heard it's not a safety thing, more a mx headache.
