If . . .

Then . . .

(1) There is sufficient structural redundancy to prevent catastrophic failure of the platform or structure under consideration,

The results of the fatigue analysis must indicate a minimum calculated life of twice the design life of the platform.

(2) There is not sufficient structural redundancy to prevent catastrophic failure of the platform or structure,

The results of a fatigue analysis must indicate a minimum calculated life or three times the design life of the platform.

(3) The desirable degree of redundancy is significantly reduced as a result of fatigue damage,

The results of a fatigue analysis must indicate a minimum calculated life of three times the design life of the platform.

(b) The documents incorporated by reference in § 250.901 may require larger safety factors than indicated in paragraph (a) of this section for some key components.
