There is no track record for the "Stub Pipe" issue, and since RR "Sprung" the Stub Pipe issue on everyone, in hopes of diminishing the severity of the Powerplant issue, The 75 cycles is related to the Splines, the AD's, and the 972. 75 cycles is about ninety days for Qantas, as I reckon it, and the AD has not been satisfied. The Oiling issue is new, at least as far as RR would have it.
That's certainly my interpretation based on what little I know of such matters.... Back to lurking now!
Cheers,
