My airplane is still down for maintenance, and in this video I explain that the problem is lifter spalling and what we're doing to repair the airplane. There were some shipping delays and other reasons. In doing research for this video and the repair, I'm finding this is not an uncommon issue on CM engines, and there is a "Service Information Directive SID05-1B" from 2005 and updated in 2016 that explains how to inspect the engine for this sort of abnormal wear
