Thanks John,
Seems to me the roller is probably secondary - The carrier deformation indicates that tremendous inertial forces were in play which could cause pinion deformation and roller ejection. but it could have gone either way. Early, we postulated that the pinion fractures could be the same reason, but the evidence of fatigue tells us otherwise. You are probably on to something about eccentricity. What is strange about this arrangement is the spherical bearings. They allow the pinion to float, but if the alignment of the sun to ring is held, then why need it. The first stage sun gear wear makes it look like a crown gear, but an ugly crown. It some point prior to SHTF, this gear was not aligned correctly with all of the pinions. It could be that a pinion was tilted so we can't say what one was 'wrong'. That goes back to the roller/ raceway..
Something tells me that, in absence of HUMS record, an acoustic analysis of the CVDR would indicate a rising background noise corresponding to epicyclic origins. AIBN does not have to tell us that yet now do they.
