Module 11. Aeroplane aerodynamics, structures and systems

If a redundant structure fails it becomes

  • fatigued
  • safe-life
  • failsafe

Explanation

A redundant (fail-safe) structure is so called because, when one member fails, the remaining load paths still carry the load and keep the structure safe until the damage is found. The structure thus behaves fail-safe rather than reverting to a safe-life or simply fatigued condition.

matth asking:

The answer is FAILSAFE due to if a structure fail other structure (redundant) carry the load.
Safe life depend on LIFE of component. After FH or FC must be replaced... means that the component must be replaced BEFORE FAIL
