11. Increased demand on finals sucked (and/or change of attitude from flaps moved) ice particles to inlets causing partial blockage to fuel line inlets from main tanks, exacerbated on right hand main tank by foreign object (scraper).
I mentioned a similar scenario a few days ago, but was shot down in flames....
As mentioned previously:
The scavenge plumbing tubing isn't large. It takes a long time for fuel to be scavenged. I don't think you're going to get a lot of slush through those pipes. Water, maybe, but someone said that even *water* in that quantity is still not enough to affect the engines that much.
To stop (wing) fuel reaching an engine, you'd have to block off both wing boost pump inlets AND the suction feed inlet.
Additional info: Note that the CT fuel scavenge system dumps liquid (fuel or water) well away from wing tank pump inlets (unlike the water scavenge system).
If it's dumping slush.. .it's dumping it well away from the pump inlets.
