The reason I initiated this discussion thread with such alarm was because it was ME in Brad's Mark-III Xtra who experienced this rudder pedal failure (not the rudder bell crank), and as you can imagine, I was a bit surprised and shaken to see that this factory-supplied part failed. I was simply looking for input from our Kolb community on whether anyone has seen this kind of failure before and what might have caused it. It was a good discussion. I agree with Hauck, that these Kolbs we fly are designed and built fairly stout - they'll endure quite a bit of abuse compared to other light planes. I still have all the confidence that my own Mark-III will last me for many more years. The rudder bar failure in Brad's Kolb was not due to excessive stomping force on the rudder pedals, as I was just putting enough pressure on the pedal to try to keep the aircraft going straight after landing. Brad plans to send the rudder pedal interlink unit back to Travis for his assessment. We have no insight into what the original builder did - maybe it was left out in the rain for a few weeks before he installed it in the aircraft, and the internal rust began growing from there. We'll share with you all what Travis tells us.

Dennis K: Did in intend to insinuate the failure was from one instance of abuse to the rudder pedal. I believe, without actually seeing the part, the failure was the result of a lot of use over the years, or something else that is not apparent from the photos. I agree, send the failed part back to Kolb and let them assess the problem. john h Rock House, Oregon ---- "KIRBY wrote: > > Hauck wrote: << I've been around Kolb airplanes for a good while.

I am amazed... you are truly taking the saying "live life to the fullest" and making it happen.. A few 8 hour days of flying is no small feat, I find I'm tired after flying my kolb around for an hour or so... A long cross country would be a huge effort for me but you just jump in and go!! Well done.. And I'm only 55.. OK I have a hip implant but still... I think this is a testament to your continual improvement of your bird, you have kept working on it to make it better and I am inspired to do the same, always think of ways to improve and keep it in tip-top condition. I carefully read all of your recommendations and think how I can use that information. Thank you. And thanks Homer, I am happy I have a KOLB which gives me the opportunity to experiment and fly LSA, inexpensively, at the same time.. its a GREAT aircraft for lots of things. Have a great time and a safe trip home. If you come by San Jose/Hollister in California you are welcome at my place anytime.
