I bought my 2001 RV-6A a year ago with 930hrs on the airframe and engine. I did that with the understanding that the TBO for the O-360-A1A engine was 2,000 hrs. This week, I was prompted by an ad I saw to go look at the Lycoming site and specifically at the Service Instructions for TBO. I was surprised to find that there is also a 12-year recommendation regardless of time. At least, that's how I am reading it. Is this accurate? If so, my plane already has 18+ years of service. Last condition inspection was done by Vic Syracuse and all compressions were good, no metal found in oil or filter. Last oil analysis was good. Is this something I need to address in the near future as opposed to what I thought was still several years off?
