This may be a stupid question, but why is the AS332L1 not included in the MGB increased inspection requirements? Different design or based on lower power/load requirements?
The GE PowerPoint on ProDAPS was an interesting read. Many areas to be improved e.g. re-tuning sensor baseline data post-maintenance to account for revised quiescent harmonics etc.
JimL, I appreciate your point on the less invasive inspections the better, but in this specific case there does not appear to be any other choice until the root cause failure mode is determined. The only good thing that comes out of these tragedies is increased awareness and focus on preventative actions.
Has anyone considered a possible manufacturing issue with the gears on this specific MGB batch? I would expect QA/QC to be very tight, but will boroscope inspections be enough or will the gears require x-ray etc. to determine serviceability?
