A results of an onsite investigation into the performance of the low pressure fuel system for two Macchi-Viper Jet Trainer aircraft are presented. Data analysed indicated little difference in the pressure drops in the fuel systems of both aircraft. However induced or suction pressure drops during engine accelerations can have a marked influence on pressure levels at the high pressure pump inlet. The low pressure pump in Aircraft A7-097 was significantly low in performance, resulting in illumination of a warning light. Australia.
