EricJ Posted May 24 Report Share Posted May 24 The IO-540 in C182Ts is derated to 230hp, but I don't think it changes the TBO (still 2000 hours on the posted doc for an IO-540-AB1A5). It's partly done just by reducing the redline from 2700 to 2400 rpm. Don't know if it makes them last longer in practice. Quote Link to comment Share on other sites More sharing options...
PeteMc Posted May 24 Report Share Posted May 24 JOHN DEKIN ARTICLES ATTACHED I really don't remember if I got these articles from John or someone else. But there is some good knowledge in them. I'm going to review them again to see what I've forgotten. @mooniac58 I think these are all in public domain now. But pull it if you think there's a copyright issue.
