Narrative:

On a flight from ft smith, ar, to dallas, tx, we noticed we were losing hydraulic fluid from the green system on our light transport. We declared an emergency and asked for direct to dfw which was approved. We arrived at dfw with no further incidents. After landing we stopped the plane, disembarked the passengers and had the plane towed to the ramp. Upon inspection the mechanics discovered a seal in the left main hydraulic pump leaking.
