As has been addressed before, the Trent/777 does just fine in Suction only regime. Also, prior post (recent) explains that a non uniform Fuel supply (eg entrained air) would prevent cavitation, not cause it. Air/Water/Additives in the Fuel have been addressed pretty much ad nauseum. I think the chances the AD is related to BA038 are quite slim, except as it may apply to the Fleet in general, though not nil. (Consider 7,500 TBI per AD)
My sense of the cavitation problem would require cold Fuel in a tight system, devoid of easily vaporised contaminants, subjected to a sudden throttle slam shock with HP's straining at a volume of Line Fuel that has substantial inertia, creating cavitation, which in turn would inhibit the free flow of Fuel. A perceived restriction/block is in there as well.
