AMC E 520(d) Strength – Local Failures
ED
Decision 2018/014/R
Local Failures of the Engine casing may include localised cracking. For
any casing design that allows for residual crack growth:
(a) it
should be demonstrated that the condition of the casing, including the maximum
predicted crack size, will not lead to a Hazardous Engine Effect;
(b) if the Failure of the casing, for instance as the result of ultimate crack growth, could result in a Hazardous Engine Effect, then the part should be classified as a Critical Part in accordance with CS-E 510(a)(2) and be in compliance with the Integrity Specifications of CS-E 515.
