Because it may be a lot simpler to inspect, check for correct function of, and replace perhaps, a bearing than it is to dismantle a main transmission when the Company in question was damned sure (based on its public utterances) that someone hadn't attached one of the three transmission mounting pins correctly ... which wasn't even the problem.
Put another way, comparing the two accidents the way you are trying to is a category error.
