DevX:
SeenItAll, surely the report means HP Turbine, not HP compressor? In over 30 years of engine development test I've yet to see an uncontained HP compressor failure. In fact the only uncontained failures I've witnesed have from HP & IP turbine discs.
No, there is historical precedent for compressor disc or spool failures. Probably much less common than turbine disc episodes. And the previously cited AD raises the suspicion further in this case.
