| Subject: | Bungee tube failure |
Hello Kitfox pilots ,
I had a suprise recently, the morning after an interesting flight
looking at local floodwater [and a good 3point landing] .
I pulled kitfox 2 from hanger over a very slight lip in door way of
hanger and noticed a strange noise .I found a broken tube on the
undercarriage .
The tube takes the strain of the 6 bungee wraps and had failed
completely under the 2nd wrap and had thus been concealed from normal
inspection . I am going to sleeve the tube to prevent another failure.
Needless to say the consequences could have been disastrous had the
failure occurred during landing or takeoff.
The aircraft has had its share of rough landings during training and
has done over 700 hours not sure of number of landings as I am not the
original owner /builder.
I suggest everyone with a few hours on bungee gear attempt to check for
cracking by moving bungeewraps sideways a little ,one at a time to
carefully check for hairline cracking .
regards to all.

That is pretty good advice, particularly since I average about 3-4 landings per
hour logged on my plane and the average of those is certainly not a "greaser".
I definitely plan on checking that out when I get home. Of course I am also
going to replace the bungees so that will aide in a good visual of the area.
Thanks for sharing your experience.

Good work and luck.
I think the earlier model has a 035 wall tube and later .049
big tensile difference.
Check my latest Kitfox Stall video............
how bout a video on the busted landing gear?
Would be great for all Kitfoxers.

| Subject: | Kitfox Corral at Sun-n-Fun |
Hi Sun-n-Fun spring breakers,
Sun-n-Fun is just around the corner at the end of March. I was
wondering if there might be a parking area where some of the Kitfox
builders and owners plan to gather or have gathered in the past? Last
year, I saw a few scattered in the homebuilt section and thought it
might be nice to corral a bunch in one area. What are your thoughts or
recommendations?

I too had experienced gear failure due to use of a thin walled replacement gear.
Luckily, this happened during a slow taxi after landing. If this happened
upon landing, it could have been catistrophic. It appears the thin wall tube
was weakening after each landing and shows a flat area on top of the tube at the
break. There's a lot to be said for a Grove Gear.

PMorel...On your pic, it looks like the weld on the underside was a little cold
and let go allowing the remaining circumference of the tube to oil can and finally
fracture. I agree however that the thick-walled tubing is a good idea, especially
in this highly stressed point.
Curious though. As I recall, most of the stress failures in Model 1's and 2's
were up in the carry through webbing over which the bungees wrap in the cockpit.
In fact, the factory told me when I got mine back in 1991 (ser# 707) that
it was actually a kind of Model 2.5 since they included extra diagonally welded
tubing in this area that would eventually be included in Model 3's and up.
