There are ongoing inspections on the GE90's 3rd and 4th stage compressor toggles, with the reinspect time dependant on the wear found, with some engines down to 25 cycle reinspects. The tolerances are continually updated as more information comes available, I would expect the limits to change again in the light of the two IFSD's recently. Many more shut downs and I would think that the ETOPS approval will start to be called into doubt.
