NOTE:
This inspection procedure is intended to inspect propeller shaft systems with 2 or 3 U-joints only.
Correct phasing of a propeller shaft refers to the relative alignment of the U-joint yoke flanges to each other to provide proper cancellation of the U-joints. The yokes should be directly aligned to within the range specified in this procedure.
