Narrative:

I landed at mkl from a routine flight from sik. A normal landing was made, but when I applied brakes, the left gear collapsed and soon thereafter all 3 gear gave way. Upon inspection of the left gear, it was discovered that a pin had sheared and this appeared to be the cause of the gear retraction. I don't know of anything that could have been done to prevent the accident, however, in future annuals, I will have all the pins in the gear examined and perhaps replaced.
