Factor of Safety of 1.5
Bill,
This factor of safety is also used on the components and systems of the aircraft build-up.
Hydraulic pipes and cables are proof tested 1.5 times the normal operating value, wings are over bent to demine wing loading and fuselage pressure cycled such that when you fly your aircraft the whole 'component' has been well and truly proof tested to cover your normal flying plus.
Don't ask about the computers please......
