Turbulence intensity applies to the air around the aircraft. The sustained load factor applies to the aircraft itself. These are apples and oranges, one cannot be directly compared to the other. In a simple model of a high-G turn, the air remains stationary, and the aircraft increases its lift N times. Thus its wings have to be designed to carry a load of N*...

My question boils down to: how an aircraft can withstand very high momentary forces but not very high sustained forces. From your question one can gather the maximum manuvering load factor has remained the same, and the turbulence intensity for design criteria has almost doubled. How is it possible? Fiber reinforced composites. These materials can ...

At this point in the video it says about a the verification of all the modifications done to a plane would be verified by an independent third party. Similarly in this website from Stirling Dynamics, I could find: Any changes to the original aircraft require a detailed analysis of the proposed changes and the presentation of design evidence to the ...

Generally no the aircraft will not need to be re-certified however the aircraft will likely need an updated weight and balance. Aircraft have their official weight and balance numbers measured as they are currently configured. If an airframe has its interior pulled out and some reinforcement done to the airframe it will need a new weight and balance drawn up....
