Reminds me of the LOT 5055 / Il-62 / Soloviev D-30 that AgentJayZ talked about that ended up killing 183 people because the engine manufacturer was low on supply of LP main roller bearings, and so used half as many and sometimes the wrong sizes of bearings. He took apart 5 of them and they were missing these critical components, and some of the engines even wobbled by having a couple of millimeters of play when they should be solid perpendicular to the the shaft.
