Narrative:

Loss of left hydraulic system. After takeoff and gear/flap retraction left hydraulic reservoir quantity depleted to zero. Left system pressure lost due to no fluid. Secured electric and engine driven pumps. Notified sju maintenance of problem and that we were returning and asked them to contact dispatch to inform them of problem. Held north of ddp NDB at 6000 ft for approximately 20 mins while accomplishing altimeter, flap, gear extension procedure. Landed straight in sju runway 8 without incident below maximum landing weight. Crash fire rescue equipment met aircraft. Gear pins installed by maintenance and aircraft towed off runway due to loss of nosewheel steering. Cause of malfunction later found out to be burst flex line in left wheel well.
