John / Kolbers -
Thanks for all your thoughts and comments on this topic.
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.

Hi John/kolbers,
Way to go, John!!!
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.
FrankD
