Mr. Gollin
The more similar the results at each engine of a fault in ETOPS the deeper the threat to the concept. By this I mean such "identical" EPR's suggest a "single" fault. Moving in reverse, the further back upstream the fault, the more troubling the implication if it can be shown that it caused simultaneous fuel starvation. Conversely, the more individual the result, the safer the format is from criticism. My first reaction to the report of the short landing was, it's Etops, engine failure is nearly impossible, and dual engine failure is out of the question. Simultaneous dual engine failure? The language in this last report also mentions no "excessive" water in the fuel. That isn't exactly encouraging.
Bsieker- The theory about cavitation being "fresh" was offered by the Boeing Safety Pilot (3-14-08): "not long before the incident". Though it is "fresh" as related to AAIB findings.
borgha- I agree the lack of any useful remedial suggestions is troubling.
