On the damage tolerance
WebDamage tolerance is the ability of an aircraft structure to sustain damage, without catastrophic failure, until such time that the component can be repaired or replaced. The U.S. Federal Aviation Requirements (FAR 25) specify that the residual strength shall not fall below limit load, P L, which is the load anticipated to occur once in the life of an aircraft.
