    Subject: Re: Allegro 2000, cracked gear leg.
    From: "Thom Riddle" <riddletr@gmail.com>
    Hello Theo, We replaced both main gear legs on our Allegro. It turned out to be less trouble than I had expected. We did NOT remove any material from the sockets where the gear legs fit into the fuselage. All the material removal was from the gear legs themselves where they fit into the sockets. We used a powered belt sander for this work and it went more quickly than I had anticipated. I suggest you do the work carefully, removing equal amounts of material, as required, from opposite sides and opposite edges. Sand and test the fitting, then sand some more and test again. Do not remove more material than necessary to get the leg to fit. Once you have them fitting nicely, I suggest you put a piece of thin rubber (like the material that a tire inner tube is made of) above the leg where it contacts the outboard part of the fuselage socket. Without this rubber, the bending leg makes contact with that sharp edge at the top of the socket putting unnecessary and undue amounts of stress on the upper part of the gear leg. The strip of rubber, perhaps 3-4 cm wide and the full width of the socket, should be glued in place on the upper surface of the gear leg or to the inside of the socket in that area. It does not have to stick outside the socket, which would be ugly, but it must come close to the outside edge of the socket to absorb the stresses of the bending gear leg. After replacing the gear legs in this manner we flew the airplane more than 300 hours with no more gear leg trouble, before selling the airplane last month. -------- Thom Riddle CFI-SP Power Plant Mechanic N1208P RANS S6S, Tailwheel, 912UL N197BG FS1/447 -------------------- Scratch any cynic, he said, and youll find a disappointed idealist.
