## Discrepancy

AFTER TAKEOFF,  WHILE TRIMMING NOSEDOWN, RECEIVED AN AMBER "PRIMARY PITCH TRIM FAILURE" CAS MESSAGE.  MX OBSERVED THAT THE LT ELEVATOR TRIM ACTUATIOR WAS MOVING VERY SLOW COMPARED TO THE RIGHT ACTUATOR, WHICH GIVES A SPLIT AND SUBSEQUENT FAILURE MESSAGE.  THIS IS THE NEW AND IMPROVED ACTUATOR THAT WAS RECENTLY INSTALLED.
