I've never actually seen an AVA stem fail, although I'm sure it has occurred. I think the AVA bars failed more often than the stems. I do have a pair of AVA bars with some nasty hairline cracks. My theory is that the horror stories about alloy parts failing suddenly and catastrophically are greatly exaggerated. In my own experience over 30+ years of cycling, alloy parts have always shown visible cracks on regular inspection long before actually failing. It seems that the hard hammering racer types usually report the sudden failures, but these are also generally the types least prone to properly and regularly inspect equipment. I think most "sudden" failures of alloy parts are actually the result of failure to inspect equipment and thus continuing to ride with clearly visible cracks. I ride Lambert "death forks", and AVA "death stems" and "death bars" without great concern, but I do inspect such parts regularly for cracks, as I do Campy NR cranks.
