(Larry Cottrell) ________________________________ Message 1 _____________________________________ Time: 07:39:11 PM PST US Subject: Kolb-List: Weak gear leg fitting? From: "Richard Pike" More FSII gear leg problems today. Several years ago we virtually totaled N582EF for a really bad landing where the welded fitting that joins the landing gear leg to the axle failed. Had the fitting not failed, it would have been bad, but not a virtual total. So we rebuilt it. Today Ed landed the FSII in a friends hay field due to a fuel problem. It was a hard landing, but nothing remarkable. It should have been maybe a slightly bent gear at worst, pull the gear leg out and straighten it. Yet the fitting failed in exactly the same fashion as happened several years ago. Once we get the airplane home - hopefully tomorrow - I plan to take the factory fittings and beef them up as much as I can. I no longer trust them, and will be welding some straps or saddles over and around them. Just something for the rest of you guys to think about.

From: Larry Cottrell I may be wrong,( the photo was so small :-) ) but the fitting appeared to be one of the early axles. Those were 60 thousands in thickness. The current models are the 120 thousand thickness. I had the thin ones on my plane and they too caused me a lot of problems. I have since gone to heat treated 4130 because of the problems with the axles and gear legs. I wouldn't go back. I realize that Homer felt that it would prevent damage to the cage to have the gear legs fail first, as a limit to the damage. That has not been reflective of my experience. Failing gear legs and sockets have caused heavy damage to the cage due to the legs failing for what would have been no more than a rough landing with the proper gear legs. for what its worth, Larry On Thu, Aug 14, 2014 at 8:38 PM, Richard Pike wrote: > > More FSII gear leg problems today.
