Got a pencil?” So began a recent phone call from my airplane mechanic. We were (well, he was) in the middle of a multi-day effort to completely overhaul my airplanes landing gear and other mechanical systems. While theres no Part 91 requirement for such a massive project, those with more experience working on my airplane type-a mid-60s Beech Debonair-strongly advocate doing this kind of service at around 4000 hours. I was slightly more than 1000 hours late. We already had spent a substantial amount of time researching sources and pricing on various replacement parts like rod ends and bearings, as well as refinishing and reusing many of the parts removed for close inspection. In all, the airplane was in good shape. Still, we opted to replace several components. Or tried to, anyway.
