Risk management decisions are not new to aviation safety and are commonly employed in manufacturer recommendations regarding retrofits and/or maintenance.
The fundamental basis of risk management is the understanding of average risk assumed in the design and operation of the product vs. what additional risk may added on top of the average for a specific flight.
In hindsight, factors of differences exist for individual flights and it is the risk management objective to limit these differences. However the biggest risk contributor has always been the "unknown" risk of problems not yet identified (hidden) which significantly contribute to the average assumed risk. With this in mind typical risk limitations are applied to the individual known contributions depending on their individual severity quotient (incident, or accident, or catastrophe etc.).
In summary, for the known risks there may have been nothing wrong in continuing the flight, assuming the risks were within expected variation levels.
