GE CF6's had a similar problem last year. I don't recall any posts over that incident and subsequent fleet check. Just because a p-clip chaffed through a pipe it does not mean to say it was poor maintenance. There are problems every day on aircraft which are due to any number of problems. If they have found that many engines with the same problem I would think it is more a design problem than poor maint, unless one man has been very, very busy or all the engineers at CX are poor, which I personally seriously doubt. I believe after most incidents it is also quite often quoted around here to await the official report and not jump to conclusions on a preliminary report, especialy one from the press (South China Post?).
