This is news. About 6 months ago, a Lancair tech rep was emphatic that the NOSE gear cylinder be setup as Scott describes in order to react the loads internal to the cylinder. Issue, as was discussed here, was that the nose gear tunnel could crack. When I asked about the mains, I was told this is not a problem because of the way loads are reacted at the main cylinder attach points. And in fact, the inboard supports for the main cylinders do look "beefy". The problem of a bent cylinder rod as Scott reports may or may not have anything to do with bottoming out the cylinder internally. What would bend that (very strong) rod? How would the forces be applied to accomplish this? I ask these arcane questions because I wonder if the rod impacted the inboard linkage attach - the one the manual warns us about. Or, if it's a misallignment during the stroke that was the culprit then changing the bottoming condition won't help. Obviously, first thing I will do when I get to the shop will be to re-inspect my installation. Ed de Chazal, Rochester, Michigan.
