Recently I was quietly celebrating my rapid accumulation of flight hours so far this year. Annie, our Commander 114B, and I have done a lot of traveling. I might even score my first 100-hour year, I thought. I realized it was also time for an oil change.
The maintenance manual says every 50 hours, but most of my pilot friends say that interval is too long. As a result, conversation in the hangar community revolves around how often you change yours and what that number says about you as a pilot—or so it seems.
