## Discrepancy

THE CREW REPORTED THAT DURING CLIMB OUT AT 3000 FEET THERE WAS A TEMPORARY LOSS OF POWER ON ENG NR 1, N1 APPROX 70%. A FEW MINUTES LATER, A SECOND LOSS OF POWER ON ENGINE NR 1, THIS TIME TO APPROX 60% N1. BOTH TIMES THRUST LEVERS WERE IN THE DETENT / CLIMB SETTING. THE AIRCRAFT RETURNED WITHOUT INCIDENT WHERE MAINTENANCE REPLACED RELAYS K0401 - K0403 - K0405 - K0407. AN OPERATIONAL CHECK FLIGHT AND SYSTEM CHECKS WERE SUCCESSFUL AND THE DISCREPANCY WAS CLEARED.
