## Discrepancy

PILOT WHO WAS ACTING AS INSTRUCTOR FOR THIS TRAINING FLIGHT REPORTED THAT WHILE LEVELING OFF, THE FO NOTED THAT THE ELEVATOR TRIM SEEMED TO BE WORKING BACKWARDS. WHEN THE FO TRIMMED FOR NOSE DOWN, THE NOSE PITCHED UP. THE CAPTAIN TOOK THE CONTROLS AND VERIFIED THAT THE TRIM WAS OPERATING BACKWARDS. THEY RETURNED TO DEPARTURE TO RETURN THE ACFT TO MX. WHEN MX INSPECTED THE ACFT, THEY RE-RIGGED THE ELEVATOR TRIM AND CHECKED IT IAW C402C MM CHAPTER 27.
