In a way, I'm with DERG on this. Time to call in ye old pump engineer. Tell to bring his cavitation check list. Go down it item by item. One of them hasn't been looked at hard.

Well, I’ve followed the thread from the start. In my opinion, the current theory is not compatible with the known parameters of the flight. The mystery of what really happened to BA038 continues.

Slush - NOT

Fuel /ice slush? Think about this. At the point where the pump goes into cavitation, the fuel pressure at the pump inlet falls to near zero. And the near zero pressure will extend back through the...

hero status

Getting that plane down in one piece demonstrated the exceptional skills of the pilots. But that was all it was; some damn good flying.

A hero is one that knowingly places himself at risk to come...

If the oil heat exchanger is located in the pipe network of only one side, then the separate systems are not mirror images of each other. Similar resonance to dis-similar systems at about the same...

I'm already on record for a theory. I'll go a bit more.

The permanent fix is to change the gear ratio for a reduction in pump speed and an increase in pump size to maintain the flow capacity.

pump cavitation

Pump output can be greatly diminished by cavitation and would give the results seen in this case.

The HP gear pumps show evidence of cavitation. Two of the principle determinants for the point at...

Sometimes it can be useful to take a theory and review it. If found to violate a known fact, it can then be eliminated as a possibility.

With that in mind, I'll take up the supposition that the...
