Manufacturing defect either material or user error maybe?

  Many manufacturing defects affect whole batches of units. People serious about preserving data with redundant arrays, tend to be careful to avoid using multiple drives from the same batch. I vaguely recall a cloud backup provider losing customer data because they failed to do this. Annoyingly I can't find it on google.

  Even in this case, after a failure of one engine, the other engine(s) are set to a higher thrust, which increases likelihood of their failure.
