One in Nov and one in May. So what? I'd be more interested in the hours flown and cycles. Having said that the Nov. incident the motor had only been on a couple of weeks!
I am a bit suprised that QF had not incorporated the SB's to alleviate a potential problem. A failure of the HPC stg1 blade is often caused by a failure upstream in the IPC, of one of the tails of the locking clips. If it unfortunately hits the blade at the root it can be a matter of about 80cycles before it parts company. No real big deal the blade is only 2.67ins x 1.72ins its just that it trashes everything aft!
