Detailed examination of both the left and right engine high
pressure fuel pumps revealed signs of abnormal cavitation
on the pressure-side bearings and the outlet ports.
Would cavitation not have to build up over a period of time in order to be described as 'abnormal'? I appreciate that if solids peppered the bearings and ports then there would be increased pitting, but to such an extent in one flight leg?
What pressure (psi/bar) is the fuel entering/leaving this device?
