Narrative:
The final steps of the engine trim procedure leaves the part-power-stop (pps) in the stowed position in accordance with the maintenance manual. Our work cards chronologically follow the maintenance manual and then call for the removal of equipment as does the maintenance manual. The next step is to safety the part-power-stop in the standard day position, then close up the engine. This is a wrong statement which will prevent the aircraft from reaching full takeoff power. By following these procedures the aircraft was in revenue service and had to abort takeoff. The problem was immediately idented and corrected without any further incident.
