This procedure is intended to apply to any aircraft fuel pump which supplies liquid hydrocarbon fuel either directly to an aircraft engine or to another pump mounted on an aircraft engine@ except that it is not intended to apply to a fuel pump mounted in a fuel tank. The procedure will be defined in terms of a recommended test set-up and a recommended testing method. PURPOSE: This recommended practice defines a procedure for testing aircraft fuel pumps for the purpose of evaluating and comparing their resistance to deterioration in endurance running under cavitating conditions. The procedure recommended herein is based on experience gathered by a number of laboratories conducting component qualification tests to MIL-E-5009A. It is intended to produce a uniform@ reproducible@ cavitating condition similar to that which is prescribed by paragraph 4.3.2.3.6 of MIL-E-5009A. The procedure recommended herein is not intended to provide a test for the purpose of compliance with MIL-E-5009A. Since the test defined herein does not provide for operation at (simulated) altitude conditions@ this test cannot establish altitude performance of the article tested.
