## Discrepancy

DURING TAKE OFF, THE CREW RECEIVED A TAKE OFF CONFIGURATION WARNING ON THE RED WARNING PANEL AND ABORTED TAKE OFF.  MAINTENANCE INSPECTED AND THE HIGH PRESSURE PUMP WAS ALLOWING FLUCTUATIONS OF THE PROP BLADE ANGLES.  MAINTENANCE THEN REPLACED THE HIGH PRESSURE PUMP IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 61-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
