Narrative:

Following regaining of control on taxiway, was instructed to proceed on taxiway V, cross runway 16R to west ramp. After doing so, I requested to taxi back to east side of airport. Tower or ground controller (cannot recall which) cleared me to cross runway 16R on taxiway V, hold short of runway 16L. I almost reached runway 16L when controller told me to stop. I realized I had crossed the hold line for runway 16L. After an aircraft landed on runway 34R (runway 16L), I was cleared to cross runway 16L to the east ramp. In fairness to myself, I was still somewhat shaken up by the first incident. The controller's alertness kept me from proceeding further towards the runway. Still, it made me again aware of the need to be extremely careful of clrncs and, in particular, when 2 parallel (runway 16R/16L) runways are involved, how easy it is to confuse the two.

Title: A C421 PLT, SHAKEN AFTER A RWY EXCURSION, TAXIED PAST THE HOLD LINE OF A RWY HE WAS TO HOLD SHORT OF.

Narrative: FOLLOWING REGAINING OF CTL ON TXWY, WAS INSTRUCTED TO PROCEED ON TXWY V, CROSS RWY 16R TO W RAMP. AFTER DOING SO, I REQUESTED TO TAXI BACK TO E SIDE OF ARPT. TWR OR GND CTLR (CANNOT RECALL WHICH) CLRED ME TO CROSS RWY 16R ON TXWY V, HOLD SHORT OF RWY 16L. I ALMOST REACHED RWY 16L WHEN CTLR TOLD ME TO STOP. I REALIZED I HAD CROSSED THE HOLD LINE FOR RWY 16L. AFTER AN ACFT LANDED ON RWY 34R (RWY 16L), I WAS CLRED TO CROSS RWY 16L TO THE E RAMP. IN FAIRNESS TO MYSELF, I WAS STILL SOMEWHAT SHAKEN UP BY THE FIRST INCIDENT. THE CTLR'S ALERTNESS KEPT ME FROM PROCEEDING FURTHER TOWARDS THE RWY. STILL, IT MADE ME AGAIN AWARE OF THE NEED TO BE EXTREMELY CAREFUL OF CLRNCS AND, IN PARTICULAR, WHEN 2 PARALLEL (RWY 16R/16L) RWYS ARE INVOLVED, HOW EASY IT IS TO CONFUSE THE TWO.
