## AMC E 660 Fuel Pump Tests (Turbine Engines for Aeroplanes)

When testing equipment susceptible to cavitation erosion (e.g. Engine fuel pumps) the possibility of such erosion being relieved by dissolved air in the test fluid should be considered and, if appropriate, some testing should be carried out with fuel at the most critical temperature and pressure with regard to cavitation erosion and having the minimum amount of air in solution that is likely to occur during normal operating conditions.
