Narrative:

Flew this aircraft on 3 successive legs. Required 4-5 units of left rudder trim in climb, 3-4 units in cruise, and 1 1/2 - 2 units in approach to keep wings level. Wrote up twice. Maintenance checked it and found everything ok. Something is wrong with aircraft. Wonder about trim available in engine out scenario.
