Since I didn't have the build instructions for the Super Chipmunk, (remember, I bought the plane assembled), I downloaded them and got to look at how the landing gear block was assembled.
I have decided that the best way to fix it is to perform surgery and replace the block. Might as well do the other side of the wing at the same time and prevent possible future block failure there.
This will prevent future collateral damage to other parts of the Chipmunk because of the other wheel folding under on another hard landing. (I tend to rip landing gear out of a lot of planes
, AKA "Crash Bill"))
