CS 29.619 Special factors ED Decision 2003/16/RM (a) The special factors prescribed in [CS 29.621](#_DxCrossRefBm1513259472) to [29.625](#_DxCrossRefBm1513259471) apply to each part of the structure whose strength is: (1) Uncertain; (2) Likely to deteriorate in service before normal replacement; or (3) Subject to appreciable variability due to: (i) Uncertainties in manufacturing processes; or (ii) Uncertainties in inspection methods. (b) For each part of the rotorcraft to which [CS 29.621](#_DxCrossRefBm1513259472) to [29.625](#_DxCrossRefBm1513259471) apply, the factor of safety prescribed in [CS 29.303](#_DxCrossRefBm1513259401) must be multiplied by a special factor equal to: (1) The applicable special factors prescribed in [CS 29.621](#_DxCrossRefBm1513259472) to [29.625](#_DxCrossRefBm1513259471); or (2) Any other factor great enough to ensure that the probability of the part being under strength because of the uncertainties specified in sub-paragraph (a) is extremely remote.
