AMC E 520(a) Strength - High Cycle Fatigue ED Decision 2007/015/R In order to minimise the adverse consequences of Failures due to unpredicted high cycle fatigue it is recommended that, normally, the relative fatigue strengths of the blade/disc are graded such that they lie in the ascending order: blade form, blade root, disc blade attachment, disc rim.
