Although I don't know how new this pinion was, I can say that it was making a minor "clackclack" sound before the failure. However, this pinion didn't need any more reason to break, given that it was a 12 tooth made 7075 aluminum and was taking the load of two CIMs.

After replacing it with a steel equivalent, the gearbox has been working great so far. (Fingers crossed)
