BA038 (B777) Thread

Quote from Swedish Steve:
On the Trent, the Fuel passes through the FOHE first when it enters the engine. So there is a chance that any ice could block the passages in the heat exchanger. In the GE the fuel goes through the pumps first, so there is good chance that any ice will be broken up in the pump.

If memory serves, that's news on this thread. If relevant, would it be practicable to re-position the FOHE, Steve? If so, would you expect the mod to be in the pipeline already (pun not intended).

Quote from Phlap1:
Just as the 747 problem unfolded, they will not acknowledge a known design fault but will piecemeal create a fix.

In the event of that being necessary, let's hope they don't hang about too long in an effort to avoid it being too obvious to potential litigants. If they did, they could end up wasting one of the luckiest breaks in aviation history.

Quote from Smilin Ed:
...it has been conclusively shown that the fuel metering valves moved to the full open position but there was no fuel to move through them. Since the valves opened, how could it be a software problem?

Looking at hypothetical software problems, could the fact that the position sensors indicated and recorded the valves fully open not be part of it?

Considering a given engine: if the valve was indeed fully open, there was certainly a flow restriction elsewhere, as you say. Was that due to a foreign-object blockage (ice, for example), a loss of pressure (and/or suction) to shift it through, or the anomalous closure of another valve?

I've read all the previous 2012 posts. Unless I missed something...

Well... There's a thought.
