As always a very informative and clear AAIB report. As they say themselves, many questions remain, I was thinking about the following items not mentioned in the report:
- what was the impact of the high air humidity during the approach? (intake through vents?)
- could the fuel temperature in some more exposed parts of the pipework (ex. the pylon) be considerably lower than the temp measured by the single main tank probe, where I assume the temps are influenced by the great mass of fuel, even in the coldest areas of the tank. Could this have caused icing or even waxing of the fuel in those cold spots downstream of the boost pumps?
