I would argue that this doesn't fall under the same category.It's how it works, you advance from the accidents with the new found knowledge. A lot was learned from the first commercial jet airliner for example https://en.wikipedia.org/wiki/De_Havilland_Comet
There was a boeing 737 issue with hard rudder locks resulting in fatal crashes, the flight data recorder data was insufficient to determine the cause. BA however had more advanced logging equipment installed on their planes and with the info they supplied the NTSB the cause was isolated to a design defect. The advanced logging equipment is not a mandated requirement and airlines did not install it due to costs.
