Broke my plane in September with a hard landing. Sheared off the left  

gearleg socket where the aluminum gearleg ends. Got the welding done  

at an FAA Repair Station shop because I have no welding experience at  

all. I did everything else with a little help on painting from my  

local flying buddies. Finished it over Thanksgiving weekend. It turned  

out nice, big thanks to Danny Still in Angleton TX for teaching me to  

finish paint. Here are some pics:

Jimmy:



I did that in 1988 to my FS.



During the repairs, we developed 4130 gear legs, extending them all the way 

in the socket until they bottomed out at the intersection of the two 

sockets.  Never had another gear leg shear the socket again, although there 

have been many hard landings since then.



Old Kolb designed the system that way.  It saved weight and material.  It 

also created a weak gear leg socket.

Jimmy, I think it looks great.  Doing a nice job yields pride of ownership that an "out of the box"owner will never have.  Let us know what you think of those fat tires after flying it for a while.

Jimmy Y:

  

 I don't think I did a very good job of explaining  my most important point of my last msg.  Old Kold designed the gear legs to  end at the midpoint of the socket, the weakest point of the socket.  That  is why it sheared when you landed a little hard.

  

 Didn't take rocket science to figure out pushing  the leg all the way into the socket until it bottomed out would spread the load  through out the entire socket, instead of concentrating it at the midpoint which  is weakest.  Acts like a shear.

Jimmy- Looks great, but how hard did you hit?  Any other damage?  My right leg bent back, but the bend ended at the entry point of the "Y".  No damage to the steel "Y".  I have the old 1" aluminum legs, and I tried to remove the aluminum bushing.  I will probably have to drill or ream it out.

I made a post about 3 yrs. ago about this same thing.  Fortunately,  the socket broke after taxiing about 30 ft. from the hangar.  The other  socket was almost broken, also.  I bought a new cage instead of welding  [glad I did 'cause I got the new style stick].

  

 If you have a FSII kitted before '97 [maybe even later than that], then you  may have the short gear legs & are headed for a major repair if you don't  replace with the longer ones.

I never had a hard landing;  it was just metal fatigue from maybe 1500  landings.

Didn't knock the breath out of me or anything, but I think I was at least 15' over the runway, maybe even more, when I stalled it. Dropped like a rock. I've already beat myself up over all the things I did wrong and what I should have done. I accepted the fact that it's time to get her fixed and lucky I didn't get hurt.No other damage other than I knocked the strobe light off the left wingtip. I hope you are recovering well from your mishap, best wishes to you.I flew the plane today for the first time in 3 months. I was a bit apprehensive during preflight, really took my time and did a triple check of everything. It was a thrill to take off and fly again,  and once I was up about 500', my apprehension turned to the pleasure that flying these great planes is. The plane handled superb, just like it always has. I got in 2.5 hours of flight and 10 landings with perfect flying weather, 60-65 deg. and 5 mph winds.I had put on new wing strut fairings, and I guess I should have riveted them with the tube set to the very front of the fairing instead of right down the middle. I was a good 20 miles from home I suddenly noticed my right side fairing violently fluttering. I grabbed it with my right hand and flew back to the airport holding it the whole way, and found that both fairings had worked their way free of the rivet heads. I just took them off and flew without them. I really didn't notice any change either, but I only cruise about 50 - 55 mph. I'm thinking about putting on my old smaller tires in place of the tundra tires I have. I think they slow me down more than anything else. It was so nice to be back in the air flying, can't wait to go back tomorrow morning and enjoy what should be more great aviating weather.Howard Shackleford wrote:>> If you have a FSII kitted before '97 [maybe even later than that], then you  >>Jimmy- Looks great, but how hard did you hit?- Any other damage?<<
