The latest set of replacement blades have done over 250 hours and I did a routine servicing and inspection yesterday. As always after removing each blade, I slide the thrust bearing assembly and spacer away from the blade root spigot to reveal the surface of the ferrule and look closely for a witness line caused by the inner edge of the bearing assembly. On one of the ferrules there is no visible line. On the next, scratching back and forth with my fingernail across a faint line all the way around the ferrule circumference doesn't result in any groove being felt. On the third, the line is more easy to see and for about 10% of the circumference my fingernail detects a very slight groove, maybe less than half a millimetre deep. On previous sets of blades, I can recall deeper grooves being seen and felt around much of the circumference on all of the blades. Anyone I've ever asked about this doesn't seem to have anything to offer, by way of an opinion on how much of a groove is acceptable and whether it constitutes a significant stress riser. So who of you has similar observations and what's your feeling about it?
