TRENT
Which is more likely? A TRENT shakes loose an oil couple, (be certain the P/R release includes "External" oil line), or Fuel Stalls in the FOHE due itinerant resonant frequency??
Or are we again up against the dolt who cannot line up a bias on a drill bore?? Times "X"?
How many duff pipes are aboard, Clive?
Look, a safety rollback of an operating powerplant is not cute. It is especially worrisome when it results from "unknown" (unspoken?) problems in a powerplant that has a long history of problems staying in one piece. The trail of failure leading to the uncontained burst includes the current issue, without exception. An institutional mandate exists to ignore the AD, shuffle "blame" around without cease, and act as if nothing is ongoing.
In an engine without a history of breaking, the oil loss and subsequent shutdown would be remarkable, but in this case, the lack of apparent concern is breathtaking.
Is quiet supposed to be a substitute for competence?? As I recall, "Low Oil" on the ECAM, displays with a sensing by the EEC of four quarts left.
