People should note that the problem SEEMED to affect both engines to a similar extent, but at slightly different times.

The latest report states that they have tested the fuel and it conforms to the required specification.

The debris was different in each wing tank and somehow would have had to have the same effect within 7 seconds on each engine (!)

The fuel metering valves were stated to have moved to the correct fully opened position and the filters filters were clean, as for the Fuel Oil Heat Exchangers one was clear and one had slight debris - the high pressure filters were clear.

It SEEMS very unlikely that the fuel was to blame, and the debris could not cause the same effect on the different engines.

-------------

I cannot see that two separate pumps with whatever minor damage could possibly both fail within 7 seconds of each other (whether or not they subsequently showed no fault).

I have no idea about what caused the problem, but would like to know more about any flowmeters that are in the system. Also about what could cause fuel aeration.

However, it gets annoying when people don't think about what the report says before posting. Anything that occurs must be able to affect both engines within a very small timescale.
