    Redressal of replacement of electrical fuel pump(s) for ROTAX (SB-051522)

    Aircraft may suffer poor fuel pump performance resulting in a MAIN and/or AUX fuel pump failure. Signs of poor fuel pump performance can be detected audibly on the ground before engine start after the Master Switch is turned ON. In addition, any illumination of the FUEL PRESS annunciator panel caution light, even momentary illumination, would be an indicator of poor fuel pump performance.
