I don’t think the report said this Titan It may of said it contributed to the catastrophic failure of the tail.
American Airlines say that they were never . . .informed by Airbus that they could not do double rudder reversals in the A-300 ..
If you did it in say a Boeing- 767/777 under the same circumstances, I do not think the same thing would happen – aircraft break up.
The reason Airbus adopted Carbon fiber tails is - to save weight and the airlines can carry more passengers. It is a “Commercial” not a engineering consideration.
