Comment on An Airbus A320 recently lost all 3 hydraulic systems at the same time. They are supposed to be redundant. How come Airbus hasn't grounded the A320?

  “Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don’t do one.?

    Safety isn’t 100% perfect and this is NOT the same thing.

    A “normal accident” is an emergent disaster, arising from a complex and highly technical system whose components are tightly coupled, meaning that the state of one component significantly affects others. Perrow wrote that in simple mechanical systems, a high degree of reliability can be achieved through the use of independent and redundant components, but as system complexity increases, especially when human organizations are involved, true redundancy among the components ceases to exist, and failures or errors may trigger a “cascade” that propagates through the system until disaster occurs. Cascades are, by their very nature, difficult or impossible to fully predict until they occur.

    Hey, you were told in no uncertain terms, first rule is we do not talk about recalls.
