Excellent report...
but I don't understand the apparent lack of logic between the prudent requirement for..."interim measures for the Boeing 777, powered by Rolls Royce Trent 800 engines" but only a recommendation that the authorities consider the implication to other engined 777's and aircraft in general.
Maybe they didn't want to get into commercial politics and passed the buck.
Since the specific mechanism is not understood I would have expected whatever interim action is taken on Trent engines to also apply to GE.
How much more efficient are the Trents?
To what extent does this reduce fuel flow in terms of cross sectional pipework terms? Significant?
The two Trent engines were exhibiting different (measured at least) fuel rates anyway!
My interpretation of the report is that the blockage was due to ice in the fuel delivery system prior to the engine unique part of the installation.
My conclusion would have been to consider both engines types equally subject to whatever caused the restriction at least until the exact mechanism is understood.
Comments?
